Avtron AV12 SMARTach™ III 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).

The universal 5-24V design drives longer cables and is protected against wiring errors and surges.

Adaptive Electronics: At power-up you know you installed it right! The green LED tells you your AV12 Sensor is aligned with the rotor and reading signal.  If at any time, the AV12 cannot produce consistent signals, the LED changes to red and the optional remote alarm contact activates. However, the encoder keeps working to give you time to schedule service.  Even wiring errors and short circuits that cause an over-temp situation will be detected and indicated by changing the LED to orange.
