X-RSM-SV2 Series: High vacuum light load rotary stages with built-in controllers
Vacuum compatible to 10-6 Torr
0.02° repeatability
4 mm aperture
21 mm total height
Worm gear driven for continuous rotation
Integrated stepper motor controller and motor driver allows for easy-to-use control
Only 4 feedthrough wires required to control all units in the daisy-chain via serial port (with an X-PIB adaptor)
For more information about the basics of a vacuum system and considerations to keep in mind when gathering requirements for your application, read our technical article, "Motion Device Design Considerations for Vacuum Applications".
Zaber's X-RSM-SV2 Series, high-vacuum compatible rotation stages are our most compact stepper and worm gear driven devices. These are stand-alone units requiring only 4 wires for power and data connection.
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.
The X-RSM-SV2 is designed with vacuum compatible materials to minimize outgassing and allow for faster pump down times. Like all of Zaber's products, the X-RSM-SV2 Series is designed to be 'plug and play' and very easy to set up and operate.
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).
