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.
