Heidenhain ROC absolute shafted angle encoders
ROC 2000 and ROC 7000 absolute solid-shafted angle encoders are circular scales that feature an absolute track with serial code structure and an incremental track that uses single-field scanning, eliminating the need for a homing routine at power-up. These encoders with integral bearing and solid shaft are suitable for applications that require higher shaft speeds or larger mounting tolerances. A separate rotor coupling is used for coupling the shaft. This enables axial tolerances of up to ±1 mm depending on the rotor coupling used. The rotor couplings can compensate for axial motion and misalignment between the encoder shaft and the measured shaft.
