X-RSM-E Series: Motorized rotation stages with built-in controllers and motor encoders
21 mm total height
0.02° repeatability
4 mm aperture
50 N load capacity
Worm gear driven for continuous rotation
Built-in controller; daisy-chains with other Zaber products
Encoder position feedback with slip/stall detection and automatic recovery
Zaber's X-RSM-E Series rotation stages are our most compact stepper and worm gear driven devices. These are stand-alone units requiring only a power supply. An indexed knob provides convenient manual control for versatile operation even without a computer. These stages connect to the RS-232 port or USB port of any computer, and they can be daisy-chained with any other Zaber products. The daisy-chain also shares power, making it possible for multiple X-Series products to share a single power supply.
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.
Zaber's positioners with built-in controllers, stand-alone controllers, and joysticks are divided into three series: the T-Series, the A-Series, and the X-Series.

Specification Charts and Notes
Thrust or torque is a function of speed. The values given above are maximums. These values cannot both be achieved simultaneously (i.e. at maximum speed, the unit will not produce maximum thrust).
