Thorlabs offers multi-position sliders with millisecond switching times enabled by Thorlabs' Elliptec™ piezoelectric resonant motor technology. Each slider is available as a standalone unit as well as in a complete package that include an interface board. Our compact and lightweight multi-position sliders all use the same custom-designed PCB, with the ELL6 featuring one motor and the ELL12 and ELL9 including two. The motors are highly dynamic and have no gearing. As the motor includes no magnets, it is compatible with
The open frame format, versatility, and simplicity of these sliders make them attractive for OEM applications, as they can be customized according to customer requirements and produced in high-volume quantities. Please see our OEM and Manufacturing Capabilities page for more information.
Control
There are multiple options for powering, driving, and controlling these multi-position sliders, which are detailed in the Slider Operation section of the Operation tab. Each slider possesses a 3.3 V serial bus and is designed to be operated with or without the interface board; the Pin Diagram tab provides pin assignments. Thorlabs offers software for our Elliptec products capable of providing full and independent control of the slider. When the interface board is used as an accessory to change the position of the carriage on the slider, the carriage's status in the software is automatically updated. Please note that the dual-position and four-position sliders are not designed for continuous operation. We recommend operation with duty cycles of 40% or less.
Multiple Elliptec devices can be controlled using the ELLB Bus Distributor or by splicing multiple connectors onto one ribbon cable. A single bus distributor can connect up to four Elliptec devices; up to 16 devices can be connected if the buses are daisy chained. This bus can be controlled one of three ways: through an interface board (included with the bundles below) connected to a PC running the Elliptec software, by connecting to an Arduino®2 or Raspberry Pi®3 board, or by wiring the connector pins to a user-supplied control board. Alternatively, up to 16 devices can be spliced onto a single ribbon cord, at which point the devices can be simultaneously controlled by the interface board or selectively controlled by the Elliptec software. See the manual for instruction on how to splice multiple devices onto a ribbon cord and the Pin Diagrams tab for pin assignments when making custom connections.
Application Idea
The multi-position sliders are well suited as filter changers, and the ELL6 is also recommended as shutter. Their carriages feature SM05- or SM1-threaded bores with 3.5 mm deep threads, and four

Handling
Our sliders and interface boards are robust to general handling. An assembled ELL9K bundle with labels indicating key features is shown in Figure 1, and a picture of an interface board is in Figure 2. To ensure reliable operation, keep the surface contacted by the motor free of oils, dirt, and dust. It is not necessary to wear gloves while handling the dual-position or four-position slider, but avoid touching the surface contacted by the motor to avoid transferring contaminants to it. If it is necessary to clean the surface contacted by the motor, it can be wiped using KW32 or similar extra low lint sheets and isopropyl alcohol or mineral spirits (white spirit). Do not use acetone, as this solvent will damage the plastic edge of the slider's carriage.
The open frame format of these sliders can tolerate up to 8 kV of static discharge. ESD precautions should be taken, as an electrostatic discharge can produce an electrical signal that may cause an unintended movement of the carriage. Avoid subjecting the structural PCB to loads in excess of 500 g. If an excessive load is applied the PCB may bend, which will degrade the performance of the slider.
Mounting
These multi-position sliders may be operated with the slider mounted vertically (upright) or horizontally (laying down), assuming certain conditions are met. When the slider is oriented vertically, ensure that the carriage translates side-to-side, rather than up-and-down, as the effects of gravity substantially reduce the maximum load that may be translated. When it is mounted vertically, the slider may be oriented with the motor(s) above or below the carriage. The recommended orientation is with the motor(s) below the carriage, as is shown in Figures 3 - 7, which minimizes the chance of any dust or particulates displaced during operation settling on the surface of the optics mounted in the carriage. When mounting the slider horizontally, ensure that the installation does not bend the PCB. In all cases, do not allow anything to interfere with moving parts of the slider and make sure that the slider and the mounted optics are secure to avoid jostling during motion.
There are several options for mounting the sliders. The ELLA1 Post Mount Adapter, which is available below, fastens directly to the back of the slider's PCB. As shown in Figure 3, the adapter can then be used to mount the slider to a Ø1/2" post. The compact dimensions of the ELLA1 allows sliders to be placed one behind the other while minimizing the space separating them, as shown below. The adapter can also be integrated with Thorlabs' 30 mm Cage System components and/or SM1-threaded components, such as lens tubes. Alternately, 30 mm cage system components alone can be used to mount the sliders. An example of this is shown in Figure 4, in which a CP33 Cage Plate, four ER1 rods, a Ø1/2" post, and a post holder mount and support the assembled ELL6K.
Loading
The maximum total load specification of 150 g refers to the weight of the load mounted to the carriage, and does not include the weight of the slider. For example, the weight of the unloaded ELL6 slider is approximately 22 g, and the maximum allowed weight of the mounted components is 150 g; the combined maximum permitted weight of the slider and mounted components is 172 g. The sliders are designed to be compatible with 30 mm cage system components.
Supplying Power
Using the Interface Board
Even though ultrasonic voltage signals are required to operate the motors, the stage is powered by applying a DC voltage signal to the interface board. The electronics on the board, which convert the applied DC signal to a sinusoidal signal oscillating at the desired resonant frequency, make this possible.
The ELL6 includes one motor and the ELL12 and ELL9 include two. Because of the lower power requirements of the ELL6's single motor, it is possible to supply power to the ELL6 through the Micro-B USB connector on the interface board. A 5 V power supply is not included in the ELL6K bundle; however, if it would be convenient to use a 5 V power supply, the TPS101 is compatible with the interface board. Operation of sliders with two motors requires a 5 V power supply, and one is included in the ELL12K and ELL9K bundles.
An advantage of powering the ELL6 using the Micro-B USB connector on the interface board is that a computer can be used to simultaneously control and power the slider. Laptops can supply the amperage necessary to enable switching between positions on the ELL6 dual-position slider; however, some laptops may not be able to supply the 1.2 A required to perform a search for optimal resonant frequencies, which is described in the following Resonant Frequencies section. When this is the case, and it is necessary to perform a search for optimal resonant frequencies, an alternate power source capable of delivering the needed amperage must be used to supplement the power provided by the laptop.
When the setup includes the ELL12 or ELL9 and an interface board, power is supplied through the 5 VDC power socket. As the Micro-B USB connector does not supply power sufficient to drive both motors, this connector is used only for computer control of the slider.
Without the Interface Board
When these sliders are incorporated into an application without the interface board, the connection with the power source is made using the pins on the Picoflex® connector. A pinout diagram of this connector is included in the Pin Diagram tab, and information on powering and addressing the slider given in its manual and the communications protocol manual respectively.
Operational Principle of the Motor
The Elliptec motors move the carriages on the sliders between positions, and the direction of the translation is determined by the ultrasonic frequency driving motor's piezoelectric elements. For each motor, there is one ultrasonic resonant frequency that will push the carriage forward, and another that will pull the carriage backward. Operating a motor at one of its resonance frequencies causes the tip of the motor to continuously cycle in a tight clockwise elliptical path. When the motor is driven at its other resonance frequency, the tip of the motor cycles through that same path in a counterclockwise direction. Both resonance frequencies are around 100 kHz. The total displacement at the tip of motor is a function of the mechanical load it is driving and the voltage supplied to the piezo element. In the case of no loading and a 5 V maximum driving voltage at a resonant frequency, the tip of the motor expands and contracts no more than a few microns while tracing the elliptical path. Please see The Elliptec™ Motor tab for more information and an animation that illustrates the operational principle of the motor.
Resonance Frequencies
On power-up, the factory default setting instructs the slider to search for the resonance frequencies that will deliver the best performance. During this process, the slider will translate between the forward and backward positions. At the conclusion of this calibration process, the slider is in the backward position. If this movement on start-up is undesirable, it is possible to disable this calibration procedure by using the serial port to initialize the frequencies on power-up. A new search for optimal resonance frequencies may be performed at any time; to maintain optimal performance, it is recommended that new searches be performed after changes in loading and/or ambient temperature. Please see Section Section 4.4 of the manual for details.
Slider Operation
Note that our sliders are not intended for continuous operation. We recommend operation with duty cycles of less than 40% during general use, while operation with duty cycles greater than 60% should be limited to a few seconds.
The movement of the slider's carriage may be controlled by pressing buttons on the interface board, through computer control via the Elliptec™ software package that may be downloaded, or by sending simple signals to digital lines on the slider board. The constant drive power results in a linear speed profile, which enables the motor to accelerate and decelerate in a few microseconds.
The interface board may be used as an accessory while interfacing with the slider through the Elliptec software; all changes in the position of the carriage that occur as a result of pressing buttons on the interface board are registered by the software, and the software may independently control the carriage while the interface board is connected. The buttons on the interface board can be seen in Figure 2.
Multiple Elliptec devices can be be controlled using the ELLB Bus Distributor or by splicing multiple connectors onto one ribbon cable. A single bus distributor can connect up to four Elliptec devices; up to 16 devices can be connected if the buses are daisy chained. This bus can be controlled one of three ways: through an interface board (included with the bundles below) to connect to a PC running the Elliptec software, by connecting to an Arduino® or Raspberry Pi® board, or by wiring the connector pins to a user-supplied control board. Note that if an interface board is used, its on-unit buttons will be disabled. Alternatively, up to 16 devices can be spliced onto a single ribbon cord. The devices can then be simultaneously controlled by the interface board or selectively controlled by the Elliptec software. See the manual for instruction on how to splice multiple devices onto a ribbon cord and the Pin Diagrams tab for pin assignments when making custom connections. The communications protocol manual describes how to use the software to individually address each connected device. A link to download the software and accompanying documentation can be found in the Software tab.
Figures 5 - 7, as well as the animation included on the Overview tab, show the operation of the ELL6 slider using the interface board. By pressing the button on the interface board marked 'FW,' as is about to be done in Figure 6, the slider is sent to the forward position. The slider will return to the home position when the button on the interface board marked 'BW' is pressed.
When using the interface board to control the position of the carriage on the ELL12 or ELL9 sliders, the JOG button is also used. If the slider is facing forward and oriented vertically with motors beneath the translating mount, press and hold the JOG button then press the FW button to move the carriage one position to the observer's right. Press and hold the JOG button and press the BW button to move the carriage one position to the observer's left.

The Components of the Elliptec Motor
Click to Enlarge
The Elliptec Piezoelectric Resonant Motor
The Elliptec™ Piezoelectric Resonant Motor
Thorlabs' Elliptec™ piezo resonant motor, shown at right, is lightweight, with a mass of 1.2 g, and compact: the dimensions of the resonator housing, excluding the spring, are 8 mm x 4 mm x 20 mm.
Components of the Motor
The components that compose the motor are shown at far-right. The piezoelectric element is press fit into the aluminum resonator, which has been precisely designed and machined to produce the desired elliptical motion at the tip and to interface optimally with the driven module. The free ends of the spring are integrated with the resonator housing. The wires, which are soldered to the top and bottom of the piezoelectric element, deliver the voltage signal that induces the piezoelectric element to vibrate at ultrasonic frequencies.
When the motor is built into a system, the open loop of the spring is bolted to a sturdy surface that is stationary with respect to the item to be driven, and the tip of the resonator is placed in contact with the item. The purpose of the spring is to maintain constant contact between the tip of the resonator and the driven item, and the direction of motion is determined by the resonance frequency at which the piezo element is driven.
Elliptical Motion and Comparison with Conventional Motors
The motor is operated by driving it at one of its two resonance frequencies. A voltage signal oscillating at an ultrasonic frequency is applied to the piezoelectric chip, which responds by expanding less than a micron and then contracting back to its original dimensions at the frequency of the driving signal. This rapid-cycling change in the chip's dimensions causes a vibration in the aluminum resonator housing. When the vibration is at one of the housing's resonance frequencies, a pushing motion results at the tip of the motor. When the vibration is at the other resonance frequency a pulling motion results.
As illustrated in the video, the pulling and pushing motions result from the tip of the motor tracing an elliptical path in space when the motor operates at resonance. The selected resonance frequency controls the direction of the cyclical motion. The motor's tip traces one half of the ellipse as it expands and the other half as it contracts. When the motor pushes the driven item, the motor's tip is in contact with the item while the tip expands; the two are not in contact while the tip contracts. The converse is true when the motor pulls the driven item in the opposite direction. The total displacement at the tip of the motor is a function of both the mechanical load it is driving and the voltage supplied to the piezo element. The maximum displacement can be up to a few microns when the peak driving voltage is 5 V.
The motor behaves in many ways like a DC or electromagnetic stepper motor, but it does not suffer from many of the drawbacks of these conventional motors. Unlike conventional electromagnetic motors, which must overcome inertial delays to come to a stop, the highly dynamic Elliptec motor can stop within microseconds. As it has no gears, it does not exhibit backlash. Since it possesses no magnets, it is compatible with use in environments sensitive to electromagnetic interference. The motion of the driven element is continuous and smooth. As the tip of the motor must be in contact with the driven item to induce motion, the motor possesses the safety feature of an inherent friction brake. When in contact with a plastic surface, the motor operates virtually silently.
For OEM applications, the motor can be manufactured in volume at low cost, and it can be driven by inexpensive analog electronics. It does not require microprocessors or software; however it is compatible for use with them.

The Elliptec Piezoelectric Resonant Motor Control Software GUI
Software for Devices Driven by Elliptec™ Piezoelectric Resonant Motors
All devices based on the Elliptec™ resonant piezo motor may be controlled by the Elliptec system software, which features an intuitive graphical user interface (GUI). The source code, in C# format, is included in software bundle available for download, and custom applications can be created in any language. The image at right shows a screen capture of the GUI, and the button that follows links to the download page.
Commands are entered in the Sequencer command / wait order section located at the center-left of the GUI. An example of a sequence of commands that might be sent to the device is "Afw" to move the slider at address "A" to the forward position and then "Abw" to move the slider at address "A" to the backward position. The command "As1" is used to perform the frequency search that will identify the optimal resonant frequencies, for the current operating conditions, for the motor at address "A."

(posted 2021-12-09 11:47:10.013) Short comment:
It would be nice if the device would be "thinner". This could be realised by offering a slider with deeper threads such that a filter may be directly mounted in the slider without the use of additional lense tubes. There is actually a quite large gap betwenn slider and red electronic board.
Best,

(posted 2021-10-22 07:48:52.753) When using ELL6 or ELL9 products (and other USB stages), is it possible to use a USB hub (mains-powered) ?
ELL9 warns against having the component plugged in USB when a computer isn't fully on. What of a USB hub ? Can it be plugged as long as the hub is powered ? Should the cable be disconnected every time beofre we power off the computer or hub ? Under which conditions can we let an ELL stage connected ? cwright
(posted 2021-11-01 11:42:33.0) Response from Charles at Thorlabs: Thank you for your query.
This was an issue with old versions of the USB remote interface board. Version 2 onwards should not have this issue. The issue is backfeeding of current to the USB hub. The way the USB has been implemented within the computer's USB HUB will determine whether or not it is suitable and our engineers found that even within the same laptop you could have some USB ports which are OK and will not be affected and others which are not OK and could have this issue. If using the old board then the only way to be sure is to either power the PC first or to desolder the transistor (labelled Q1 on the old boards). You cannot fix this with an external HUB. user

(posted 2021-08-17 04:28:11.31) I think it should be stated more prominently (maybe on the main product page and not only in footnote (c) on the specs page) that the ELL9 can only be operated horizontally. When mounted on, e.g., a motorized rotation mount (which might be something a lot of customers think of as a possible application scenario), the ELL9 only moves correctly when aligned horizontally. In vertical orientation (rotation stage turned by 90 degrees), the motors are to weak to move even the weight of the slider alone, i.e., without any optics attached. Even though this might be obvious, it might still be a good idea to put a comment on the webpage.
In our case, we found a quick workaround, always turning the rotation mount before changing the ELL9 position, so that the slider motion always occurs in the horizontal direction. But other customers may want to use the slider at arbitrary rotation angles, which won't work out.
Apart from that, these are awesome devices. cwright
(posted 2021-08-18 05:29:28.0) Response from Charles at Thorlabs: Thank you for your feedback. We will consider adding a clarifying note to the web presentation. The behaviour in this orientation is more due to the nature of the motor than its strength. The motor's tip follows an elliptical path when active and in order to advance the moving world it must leave contact with this moving world for a short time each repetition. When used with the slider orientated vertically the effect of gravity would oppose the intended motion of the slider and cause slipping. This motion can be seen in more detail in the video on the following page:

Thank You for the information! cwright
(posted 2021-07-23 06:36:12.0) Response from Charles at Thorlabs: Thank you for your query. You can control both separately. The ELLB is most suitable when you want to have many devices on a single USB port but you can use these two on separate USB ports and they will appear to your computer as two COM ports. I have reached out to you to discuss your application in more detail.
If using Matlab we would recommend you send serial commands according to our communication protocol: https://www.thorlabs.de/Software/Elliptec/Communications_Protocol/ELLx%20modules%20protocol%20manual.pdf Luis Mollinedo

It would be great if the ELL6K (as well as the other units in this line) will be ready to controlled using LabView, in a similar way to many of other Thorlabs products.
This unit is integrated in optomechanical prototypes or setups containing many elements and imaging devices and while the stand alone software is nice, it is not practical for full system integration.
Thank you

(posted 2021-04-26 11:23:16.0) Response from Charles at Thorlabs: Thank you for your feedback. It is possible to use Elliptec devices in LabVIEW either by using the serial commands over VISA or by using the .NET DLL, detailed in the DLL which is downloaded with our software. By default it is found in the following loation: C:\Program Files\Thorlabs\Elliptec. The DLL is 64-bit, so your installation of LabVIEW would also need to be in order to use the DLL. For serial using VISA this is not important.
As you have opted not to be contacted by us please contact technical support if you have questions regarding this. jiang peng
(posted 2021-04-20 12:38:38.79) Some bugs were mainly found. The resonant motor will produce auto-fluorescence after plugging in the USB, about 100kcounts/s, which is detected by APD (Single Photon Counter), which is very fatal for microscopic fluorescence testing and will cover up when scanning imaging. For weak light signals, a single nanoparticle is usually only 15k-40kcounts/s. James Grieve
(posted 2021-03-11 20:38:22.797) When using the ELLB to control multiple stages over serial, is there any way to enumerate connected devices? The protocol manual is silent on this, mentioning only that the default address is '0'. cwright
(posted 2021-03-11 09:51:46.0) Response from Charles at Thorlabs: Thank you for your query. When using multiple stages on the same COM port you will have to change their addresses by attaching one stage at a time. This can be done using the ELLO software through the "Change Address" option at the top of the program window and then saving the change by clicking Save User Data in the "Settings" panel.
Alternatively you can send the commands 0ca1, to change the address of a stage from 0 to 1, followed by the user save command to address 1, i.e. 1us. These are described in more detail in the command protocol document: https://www.thorlabs.com/Software/Elliptec/Communications_Protocol/ELLx%20modules%20protocol%20manual.pdf user

(posted 2019-05-22 00:56:54.707) Can the ELL6 be used long-term upside down? That is, with the bulk of its PC board pointing upwards, opposite to how it is shown in all your images? I should think one concern would be whether any wear particles will slough off of the friction interface, where the "inch worm" drive oscillates. If so these particles might drop down onto the optic being moved. But any other reason this wouldn't work? AManickavasagam

(posted 2019-04-03 04:07:51.447) Hi Thorlabs service Team,
Nice little product. I am using the serial commands in python (pyserial) to access the four-position slider.
The connection is always successful and "0in" always returns the right output. Occasionally however, a "0ma00000000" is unsuccessful and returns a "signal error" - "0GS0A". Once it occurs, I can't move the stage anymore, even when I disconnect with python and connect with ELLO. (0ma attempts always return 0GS0A) Unplugging the stage resolves this issue but do you have any advice on how I could prevent this from happening?
Note: This never happened so far with the ELLO_DLL in python but I would prefer serial commands to keep the script more versatile. user
(posted 2019-04-05 07:13:29.0) Response from Arunthathi at Thorlabs: Thanks for your query. The encoder error (0x0A) returned is a discrepancy between number of count position and requested position. It is generally a mechanical issue: vibration, moving load, stage moved or stopped by hand.
It is recommended to use HOME instead of “ma” to go to the 0 position.
Home resumes the unit from error (caused by vibration) as it resets the encoder to a known absolute 0 position.
If the issue still persists please contact your local tech support team directly for further assistance. Julien PROUST

Translation:
Feedback: I want to finely move the hole positions with ELL9K, but it seems that the 'ma' (move absolute) command can not be used. I'd like for the stage to change such that we can use the 'ma' command.
Response: Thank you for your feedback. I have relayed it to the developers of Elliptec's firmware who will take it into account when planning for future releases. The 'ma' and 'mr' commands can be used on ELL9, but only to switch between the 4 slider positions. Unfortunately, we can't modify this stage's firmware in order to allow these commands to be used for fine translations. This is because ELL9, as opposed to the other Elliptec stages, lacks an encoder. With that being said, we could add a similar command that would allow one to translate the stage for a given period of time. If your stage is not responding to the 'ma' or 'mr' commands, please contact our Japanese office at sales@thorlabs.jp. lvjing

(posted 2018-03-29 14:55:49.94) Is it possible to turn off the LEDs in the interface board?
I'm using this slider to move ND filters and my optical setup is enclosed in a light tight box, because I need to perform measurement at very low light. The flat cable between the interface board and the slider is too short so I have to keep the interface board inside the light controlled box, but the light intensity of the LED on the board is not at all negligible. At the moment I'm covering the LED with black tape, but it's definitely not enough and not very nice.
I couldn't find anything about it in the documentation. It'd be great if didn't have to replace the flat cable with a longer one.

A single bus distributor can be used to control up to four Elliptec devices. The bus can be connected to a PC using the interface board provided with the bundles sold above. Note that the bus is then controlled by the Elliptec software and that the buttons on the interface board are disabled.
- Control and Power up to Four Elliptec™ Devices with One Bus
- Daisy Chain Bus Boards to Control up to 16 Elliptec Devices
- Controlled Remotely Using Elliptec System Software (See Software Tab Above)
- Connect to PC Using USB Interface Board Included with Elliptec Bundles
- Five Jumpers and Four 8-Conductor 28 AWG Ribbon Cables Included
- Compatible with Raspberry Pi® and Arduino® Boards
The ELLB Bus Distributor connects up to four Elliptec™ devices. Connected devices can be controlled with or without the interface board included with the above bundles. When using the interface board, each connected device is controlled remotely by a PC running the Elliptec software package. The interface board connects to the bus's input port labeled REMOTE; once connected, the interface board's buttons are disabled. For control without using the interface board, see the Pin Diagrams tab for custom connections.
Multiple ELLB Bus Distributors can be daisy chained to control and power up to 16 Elliptec devices; simply connect one of the four MODULE outputs to the second board's REMOTE input. Indicator LEDs are provided to show which device is active. The communications protocol manual describes how to use the software to individually address each connected device. A link to download the software and accompanying documentation can be found in the Software tab.
The bus includes a Ø6.3 mm power connector that supports a 5 V supply with a maximum current of 4 A. As more devices are connected, simultaneous control of the units will require more current to be provided by the power supply; please see the Specs tab for the amount of current drawn by each Ellitpec device. Power supply options provided by Thorlabs include the TPS101 5 V, 2 A power supply and the 5 V, 1 A supply included with the above bundles. Depending on the current draw of the Elliptec devices connected, these supplies provides enough current to power two devices simultaneously.
Fourteen control pins, detailed in the image to the right, are included for additional functionality. Four pairs of pins are each shorted with a jumper that, when in place, enables the Elliptec software to receive feedback from connected Elliptec devices. The pair of pins labeled LED is shorted with a jumper that, when removed, will disable the indicator LEDs. The 5V and GND allow an optional, user-provided 5 V, 2 A power supply to be used in place of a source connected to the Ø6.3 mm power connector. The RX and TX pins can be used to control the bus with a Raspberry Pi® or Arduino® board, respectively, instead of the Elliptec interface board.
The board is mounted using the Ø3.5 mm through holes provided in each corner. Four 8-conductor, 28 AWG ribbon cables are included.

The ELLA1 mounts to the back of the slider's PCB using the four 4-40 threaded holes, also compatible with 30 mm cage system components.
- Mounts Directly to Slider PCB
- Front Clearance Slot Accommodates Protrusions on Back of PCB
- Four Counterbores for Use with 4-40 Threaded Screws
- One Counterbore for Use with 8-32 (M4) Threaded Screws
- SM1 (Ø1.035-40) Internal Thread
The ELLA1 Post Mount Adapter securely fastens to the back of the multi-position slider PCB using the four included 4-40 screws. The slider can then be mounted to a Ø1/2" post using the counterbore at the base of the adapter and an 8-32 (M4) screw (not included). A lens tube or other component can be mated to the adapter using the internally SM1-threaded (1.035"-40) bore. The four counterbores can also be used to connect the ELLA1 to a 30 mm cage system via Ø6 mm cage rods.
With overall dimensions of 40.0 mm x 44.0 mm x 14.0 mm and a design that positions the mounting post close to the back of the slider's PCB, the adapter is especially recommended for applications that require placing sliders one closely behind the other. The geometry of the adapter allows the optics mounted on one slider to be positioned above the post used to mount the slider directly in front. These adapters are also convenient single-component mounting solutions for general applications.
