RSM-E Series
Motorized rotation stages with built-in motor encoders
About This Series
Zaber's 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 AutoDetect. Once connected, the X-MCC controller will automatically detect and configure the RSM-E.

- Integrated motor encoder, provides easy-to-use closed-loop motion.
- 200 step per revolution stepper motor, microstepped up to 256x to provide smooth and precise motion.
- The interlocking alignment system makes it easy to set up a gimbal system.
- M2 (20 mm pattern) and M3 (32 mm pattern) mounting holes provided.
- DB15 male, inline connector with AutoDetect allows the RSM-E to be easily connected to an X-MCC Series controller and ready to use without additional user input.
- An additional knob for coarse positioning without power.
Easy Set-Up
With AutoDetect, the X-MCC controller will automatically detect and configure the peripheral. Zaber's devices can share both data and power through a daisy-chain, which reduces cabling and makes set-up as easy as 1, 2, 3:
- Connect the X-MCC controller to your computer.
- Connect the controller to the peripheral and plug in the power supply.
- Send instructions or automate your set-up using the Zaber Launcher.

For more details on daisy-chaining, read our technical article, "Daisy-chaining Data and Power to Reduce Cabling", or to determine which accessories you need for your system, try our Connection Guide Tool.
