The Heidenhain RON 786 is an angle encoder with integrated stator coupling and a hollow through the shaft.

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 the angular acceleration of the shaft. Thanks to its design, the system accuracy includes the error of the shaft coupling. The RON 786 features a line count of up to 90,000 lines, resulting in very high system accuracy.
