RST-DE Series: High precision motorized rotation stages with built-in direct reading encoders and Auto Detect
Speed up to 24 °/s and torque up to 10 N⋅m
50.8 mm (2 inch) aperture with kinematic mounting options for repeatability of assembly
50 kg centered load capacity
Continuous 360° rotation stage
Direct reading encoder for position correction; stage accuracy to 0.01°
Designed for use with an X-MCC Series stepper motor controller or any 2-phase stepper motor controller
With Auto Detect, the X-MCC controller configures its settings automatically for the connected peripheral
Zaber's RST-DE Series products are motorized rotation stages with built-in 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, angular positioning applications. RST-DE stages are designed for plug-and-play use with any of Zaber's controllers. Set up is easy with Auto Detect. Once connected, the X-MCC controller will automatically detect and configure the RST-DE.

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).
