Available from Renco Encoders, the RCH50 hollow-shaft encoder is equipped with an incremental TTL encoder capable of resolutions to 4096 CPR as well as outputs for commutation of brushless servomotors. The commutation signals have been implemented with precision optical logic to provide accurate switch points for smooth, efficient motor operation at any pole count, the company says.


Built to withstand high temperatures, the encoder provides frequency response to 300 KHz. Its internal bearings and flexible stator coupling are designed to reduce hassles during installation. In addition, the unit’s flexible mounting plate can accommodate large axial shift movement.
