Stepper Motor Cables
Thorlabs offers a variety of cables to support several stepper motor actuator and controller combinations. Supported stepper motors include our ZST, ZFS, and DRV actuators; supported controllers include our BSC benchtop controllers, our KST101 K-Cube™ Controller, and our MST602 Rack Control Module. In order to see which cable is compatible with a given combination of stepper motor and controller, please see the table below. The pin assignment for each cable is given in the Pin Diagrams tab. Please note that these cables cannot be used with motors and controllers that do not match their pin assignment, even if the connectors are the same.

DC Motor Cables
The PAA632 is a 2.5 m cable for our Z8 series of DC motor actuators. This cable is intended to be used with the KDC101 K-Cube DC Servo Motor Controller. The pin assignment for this cable is given in the Pin Diagrams tab. Although it uses a 15-pin connector, this cable is not compatible with any of our stepper motors.

Why should the PAA614 not be used with the Z8 DC Servo Motor Actuators? What is the difference to the PAA632? Are they not both just DE15 Male to DE15 Female cabels with different lengths?

Response from Radu at Thorlabs: While both cables have the same connectors, they are wired quite differently. One can see these differences in the pin diagram tab. PAA614 was designed to be used with our non-encoded stepper motor stages or actuators, while PAA632 was designed for encoded, brushed DC Servo stages or actuators. Consequently, PAA614 has four pins who play an active role in powering up a two-phase stepper motor, while PAA632 only has two pins dedicated to powering up a motor.

DA14 and DE15 are all regular connectors widely used. For example DE15 is used also for VGA. These connectors cost everywhere about 1 - 2 dollars. Frequencies of operations are not very high either, so no need for specially high frequency cables. Thus, wires are not that expensive either. So why all the wire extension products PAA6xx cost above 50 dollars (some way above 50 $) ??

I have been waiting for a TST101 motor extension cable such as the PAA614 However, I am disappointed that the PAA614 extension cable is only 1 meter - why don't you have a longer version of the PAA614 such as the PAA632? Thank you, Andrew Yablon andrew_yablon@interfiberanalysis.com

Thank you for contacting us. We can offer PAA614 as a special in lengths of 3 and 5 m. However, we do not recommend going over 5 m as the increase in resistance can cause some signal errors.

The cables can be very difficult to find. Please refine the search so searches like "stepper motor cables" will return results. Also, why not put ALL motion control cables on the same page???
