Features:

1. Control all units in the daisy-chain via serial port (with a locking X-SDC cable) or USB (with an X-USBDC cable).
2. Daisy-chain additional units with a locking X-DC02 cable or X-DC06 cable. Power can also be shared in the chain.
3. Integrated controller and stepper motor driver provide easy-to-use motion.
4. Integrated motor encoder, provides easy-to-use closed-loop motion.
5. 200 step per revolution stepper motor, microstepped up to 256x to provide smooth and precise motion.
6. Stage top supports multiple mounting options.
7. 50.8 mm (2′) or 101.6 mm (4′) aperture with H7 tolerance.
8. Holes on bottom and side provide flexible mounting options.

 

Zaber Technologies’ X-RST-E Series products are motorized rotation stages with built-in controllers and motor encoders. Rated for up to 300 kg centered load capacity and 70 N⋅m of torque, they are ideal for high load, angular positioning applications. They have large diameter apertures for a variety of thru-bore applications.

They are stand-alone units requiring only a standard 24-48 V power supply. An indexed knob provides smooth manual control at variable speeds in both directions for versatile operation even without a computer. Press and hold to switch between velocity mode and position mode, turn to move the stage, and press to stop.
