SMARTach II™ Magnetic Encoder, 1 1/8" Hollow Shaft Mount

AV685 hollow shaft encoders survive the worst conditions: dust, dirt, liquid sprays, and temperature extremes from -40°C* to +120°C*!

The dual, replaceable sensors are interchangeable between AV485, AV685, and AV850 and feature high-power outputs that drive long cable lengths easily. These AV5 SMARTach II sensors have the best protection of any encoder—from surges, wiring outputs to power, ground, between phases, or even short circuits!

The green diagnostic LED on the sensors assure you that the encoder is outputting ideal signals—no more false drive trips.

If for any reason, the signal is not ideal, the light turns red, and an alarm contact notifies the operator. However, the AV685 keeps working. This enables maintenance to be scheduled, and unscheduled downtime is eliminated!

The durable hollow shaft design tolerates huge axial movements, and withstands more shaft runout than any other encoder available.

So if you want the highest reliability most durable encoder in your mill, select AV685.
