AV12 Sensor for AV125 Encoder

Avtron AV12 SMARTach II™ sensors are magnetoresistive, severe duty incremental quadrature sensors for the AV125 rotary encoder. The AV12 is also usable in applications where an encoder housing is not needed – simply mount the AV12 with your bracket, and use an AV125 or other rotor. 

The AV12 + AV125 rotor allows large through-shaft applications up to 7 7/8" [200mm], ideal for large hollow shaft motors, large brakes and applications requiring large bore hollow shafts for application cooling water or cooling air.

The AV12 offers a full range of electrical connector options, including IP67 cable, IP66 MS connectors, and IP65 Industrial with built-in terminal strips. The AV12 sensor is fully protected against all types of wiring errors, including short circuits, reverse voltage, and phase-to-phase shorts. It is one tough sensor! For smaller bore applications, use AV5 sensors with the AV685 or AV850 encoder (or as stand-alone).
