Overview
The Red Lion Controls 4701200 shaft encoder is a rotary transducer engineered for accurate position and velocity feedback in industrial automation systems. Rated at 1200 pulses per revolution (PPR) and 12VDC operation, this incremental rotary encoder converts shaft angular displacement into digital pulse signals suitable for PLC inputs, motion controllers, and speed monitoring applications. Built and tested to US manufacturing standards, it delivers reliable performance in demanding production environments.
