Incremental Optical Encoders

Our Incremental Optical Encoders produce digital output related to the position of a rotating shaft, providing feedback elements in closed-loop control systems. You can use our encoders with external electronics, such as counters, to accumulate data to determine position, speed, and direction. Use these encoders when position retention is not required during a loss of power.

High-frequency Incremental Optical Encoders

Our Bulletin 844D High-frequency Incremental Optical Encoders mount directly to the monitored shaft by a split collar clamp on the encoder, eliminating the need for mounting plates and flexible couplings. You can install through-shaft models by inserting the monitored shaft completely through the encoder. Blind-shaft models only require insertion of the end of the shaft.
