Select from the options below to find the model that’s right for you.

Please see the Series Specs tab for common specs for the RSM-E series, and refer to the Options tab for further details of each model.

Zaber Technologies Logo
  • 50 N load capacity
  • 0.02° repeatability
  • 21 mm total height
  • 4 mm aperture
  • Worm gear driven for continuous rotation
  • Encoder position feedback with slip/stall detection and automatic recovery
  • Designed for use with an X-MCC Series stepper motor controller or any 2-phase stepper motor controller
  • With Auto Detect, the X-MCC controller configures its settings automatically for the connected peripheral



1. Integrated motor encoder, provides easy-to-use closed-loop motion.
2. 200 step per revolution stepper motor, microstepped up to 256x to provide smooth and precise motion.
3. The interlocking alignment system makes it easy to set up a gimbal system.
4. M2 (20 mm pattern) and M3 (32 mm pattern) mounting holes provided.
5. DB15 male connector for quick connection and automatic detection with Zaber Technologies’ X-MCC single or multi-axis controllers.
6. An additional knob for coarse positioning without power.

Zaber Technologies’ RSM-E Series rotation stages are our most compact stepper and worm gear driven devices. Self-aligning feet and mounting points make it easy to set up multi-axis tilt or gimbal systems using the GSM tilt devices or AP146 and AB147 brackets.

RSM-E stages are designed to interface with our X-MCC Series universal motor controllers. Set up is easy with Auto Detect. Once connected, the X-MCC controller will automatically detect and configure the RSM-E.
