The Heidenhain RON 285 is an incremental angle encoder with integral bearing and integrated stator coupling. The compact design is ideal for limited installation space and the hollow through shaft allows for additional room for power lines or wiring. The stator coupling easily connects the measured shaft directly to the shaft of the angle encoder.

 

The design and mounting of the stator coupling absorb the torque caused by friction in the bearing, particularly during angular acceleration of the shaft, which allows the system accuracy to include the error of the shaft coupling. The RON 200 series angle encoders have a high line count of 18,000 lines, boasting higher accuracy.
