X-RST-DE Series: High precision motorized rotary stages with built-in controllers and direct encoders
Direct reading encoder for position correction; stage accuracy to 0.01°
50.8 mm (2 inch) aperture with kinematic mounting options for repeatability of assembly
50 kg centered load capacity
Speed up to 24 °/s and torque up to 10 N⋅m
Built-in controller; daisy-chains with other Zaber products
Multiple X-Series products in a daisy-chain can share a single power supply
Zaber's X-RST-DE Series products are motorized rotation stage devices with built-in controllers and direct reading encoders for high accuracy motion. Rated for a 50 kg centered load capacity and 10 N⋅m of torque, they are ideal for high load, high precision, angular positioning 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.
The stages connect to the USB 2.0 or RS-232 port of any computer and can be chained with several units per chain. They can be chained with any other Zaber products. Convenient locking, 4-pin, M8 connectors on the unit allow for easy and secure connection. The chain also shares power, so multiple X-Series products can use a single power supply.
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).
