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.

Bulletin 844D High-Frequency Hollow-Shaft Incremental Optical Encoders

844D High-Frequency

Bulletin 844D Blind-Shaft and Through-Shaft incremental 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 install through-shaft models by inserting the monitored shaft completely through the encoder, while blind-shaft models only require insertion of the end of the shaft.


Bulletin 847 High-resolution Incremental Optical Encoder

847 High-resolution

Our Bulletin 847 High-resolution Incremental Optical Encoders feature a robust mechanical design and a metal code disk which provides a rugged bearing system that fits nearly all applications. Built to withstand shock, vibration, and a wide range of operating temperatures, these compact encoders are available with flange, hollow shaft, and blind hollow shaft options.
