Products and Solutions

Position-Pro Intelligent Sensor Tech offers a wide variety of rotary encoders for every feedback application including incremental, absolute, miniature and heavy duty rotary encoders. Rotary encoders come in 3 major mounting styles: hollow-shaft (hollow-bore or through shaft), hub-shaft (hub-bore) or shafted. Hollow-shaft and hub-shaft rotary encoders mount directly to a motor shaft typically using a tether. Shafted rotary encoders mount using a flexible coupling.

 Absolute rotary encoders measure actual position by generating unique digital codes or bits (instead of pulses) that represent the encoder's actual position. Single turn absolute encoders output codes that are repeated every full revolution and do not output data to indicate how many revolutions have been made. Multi-turn absolute encoders output a unique code for each shaft position through every rotation, up to 4,096 revolutions. Unlike incremental encoders, absolute encoders will retain correct position even if power fails without homing at startup.

 Incremental encoders provide speed, direction and relative position feedback by generating a stream of binary pulses proportional to the rotation of a motor or driven shaft. Dynapar offers both optical and magnetic incremental encoders in 4 mounting options: shafted with coupling, hollow-shaft, hub-shaft or bearingless. Single channel incremental encoders can measure speed which dual channel or quadrature encoders (AB) can interpret direction based on the phase relationship between the 2 channels. Indexed quadrature encoders (ABZ) are also available for homing location are startup.
