Renco Encoders introduced the RCH50 hollow-shaft encoder. The foundation of this product is a custom Opto-ASIC supporting incremental encoder line that counts up to 4096 as well as outputs for commutation of brushless servo-motors. According to the company's press release, the commutation signals have been implemented with precision optical logic to provide accurate switch points for smooth and efficient motor operation at any pole count. The internal bearings and flexible stator couplings simplify installation on any motor.
