• Lockable for Added Security

This versatile drawer assembly is ideal for general storage. It fits the TFR19 19" rack chassis detailed above and is available in 3 heights: 2U, 3U, and 4U. The drawer is made from 1.2 mm (0.05") thick steel with a black-powder-coated paint finish. It moves on smooth roller bearing runners and features a coupling on the drawer slide, allowing for removal of the drawer from the housing. Each drawer is lockable and comes with two keys, four 12-24 screws with nuts for securing the drawer to the rack chassis, a rubber base mat, and an RAU001 divider kit.

Equipment Rack with Optics stored in an RK4102 Shelf and Optomechanics Essentials Kits on RK4101 Shelves

Thorlabs' Rack Shelves are ideally suited for storing optomechanical components in a standard 19" rack. The RK4101 Rack Shelf provides a flat surface that is perfectly sized for holding our optomechanics essentials kits. The RK4102 Rack Shelf contains 77 Ø1/2" holes on 1.5" centers, allowing components mounted on Ø1/2" posts to be conveniently stored.

When used with our 19" equipment rack, these shelves take up 3.5" or 2U of space. These shelves attach to a standard 19" equipment rack using 12-24-threaded mounting screws, which are not included. Mounting screws are sold at the bottom of the page (Item # RK5000).

• Easy Access to Optical Layout
• Fully Protected when Closed

These versatile prototyping Rack Box Systems are ideal for building custom fiber-based assemblies. Fourteen subpanel slots allow for an extensive series of quick-connect subpanels that provide support for fiber optic and electrical systems. Subpanels designed for fiber connections, electrical connections, cooling fans, and AC power entry are available below, as are blank panels. The chassis is offered without subpanels for customers wishing to build application-specific systems.

These systems lock the chassis in place when open. To close the chassis, press the green button located on its side (see image to the right). When the chassis is closed, the maximum height of a mounted assembly is 4.7" (119.4 mm).

These rack boxes attach to a standard 19" equipment rack using 12-24-threaded mounting screws, which are not included. When used in a rack system, the height of the rack box is 5.20" or nearly 3U. Mounting screws are sold at the bottom of the page (Item # RK5000).

Opened EC2U Rack Enclosure
for Electronics

• Empty Housings for Electronic Assemblies
• Designed for 19" Racks
• Two Heights Available: 2U or 3U
• Click Here for Full Presentation

The EC2U and EC3U rack enclosures for electronics are designed for customers interested in assembling their own 19" rack-mounted electronic devices. The EC2U has a height of 2U (3.5") and the EC3U has a height of 3U (5.25"). The aluminum enclosures sold here come with blank front and rear panels, as well as two mounting brackets.

Four M3 button head cap screws are included with the enclosure for securing the ECUMB mounting board or MSBU3038(/M) breadboard inside (each sold separately). The ECUMB mounting board provides a surface with 18 mm x 5 mm slots for holding electronic components, such as PCBs, development boards, and power supplies. Alternatively, the MBSU3038(/M) breadboard features a high-density hole pattern of 8-32 (M4) and 1/4"-20 (M6) tapped holes to allow optomechanical components to be mounted inside the enclosure. The enclosures can also be converted for benchtop use using additional accessories. For more information on these enclosures and their accessories, see their full web presentation.

To open the enclosure, remove the countersunk screws on both the rear and bottom panels using the included 2 mm hex key, and then slide off the top of the enclosure. Detailed instructions on opening the enclosure are available in the spec sheet via the red Docs icons () below.

• Optical Fiber Subpanels for Our RBX32 Rack Box Chassis
• Each Panel Contains Four Fiber Mating Sleeves
  • RBX-FC: ADAFC1 FC/PC to FC/PC Mating Sleeves
  • RBX-APC: ADAFC4 FC/APC to FC/APC Mating Sleeves
  • RBX-SMAF: ADASMA SMA to SMA Mating Sleeves
• "Snap-On" Modular Design

Thorlabs' selection of fiber connection panels allows setups or instruments inside a rack box chassis, such as our RBX32 available above, to be connected to fiber components outside of the rack box. Each panel contains four mating sleeves that can be removed, allowing for panels to be customized according to the requirements of the system. The "snap-on" panel design allows for quick attachment to or removal from a rack box chassis.

Electrical connection panels and blank panels with the same profile are also available below.

RBX-FC
Our RBX-FC panel contains four ADAFC1 FC/PC to FC/PC Mating Sleeves designed for 2.2 mm wide key fiber optic cables. Flat FC/PC connectors are significantly less alignment sensitive than their angled FC/APC counterparts, making these wide-key-slot mating sleeves acceptable for narrow and wide key FC/PC connectors. Although these mating sleeves are mechanically compatible with narrow key FC/APC connectors, the wide-key slot makes it difficult to properly align the angled, narrow key FC/APC connector. For FC/APC applications, we therefore recommend the RBX-APC panel. 

RBX-APC
Our RBX-APC panel contains four ADAFC4 FC/APC to FC/APC Mating Sleeves designed for 2.0 mm narrow key fiber optic patch cables. These narrow-key-slot mating sleeves allow for proper alignment of angled, narrow key FC/APC connectors. These sleeves are also mechanically compatible with narrow key FC/PC connectors, but the flat FC/PC connector is significantly less alignment sensitive, which makes the RBX-FC wide-key-slot mating sleeves shown immediately above an acceptable alternative.

RBX-SMAF
Our RBX-SMAF panel conatins four ADASMA SMA to SMA Mating Sleeves. It is directly compatible with SMA905-style connectors and is not intended for mating an SMA906-style connector to another SMA906-style connector.

• Electrical Connection Subpanels for Our RBX32 Rack Box Chassis
  • RBX-BNC: Four BNC Connectors, Each with Rear Solder Terminals
  • RBX-DB9: Two Female DB9 Connectors, Each with Rear Solder Terminals
  • RBX-SMA: Four T4285 SMA Female-to-Female Connectors
• "Snap-On" Modular Design

These panels provide common electrical connections for standard 19" racks. Thorlabs also offers a complete selection of BNC, SMA, SMC, and banana plug electrical adapters and cables.
