The X-RSM-SV Series are Zaber's most compact stepper and worm gear driven vacuum compatible rotary stages with built-in controllers.

The integrated stepper motor controller and motor driver allows for easy-to-use control, and the worm gear allows for continuous rotation. Zaber devices allow daisy-chaining in a vacuum chamber, decreasing cables and clutter. Only four feedthrough wires are required to control all devices in the daisy-chain via serial port. These stages are vacuum compatible in high vacuum (10-6 Torr) or low vacuum (10-3 Torr).
