Product Specifications

AV125 SMARTach III heavy mill duty modular magnetic encoders fit 12.5" motor and NEMA brake flanges. Other models, from 115mm to 8.5", are available to fit other motor sizes.

AV125 is ideal for large motor and brake applications where a large diameter through-shaft is needed.  It permits shafts up to 7 7/8" [200mm] to pass through the encoder, facilitating motor-encoder-brake sandwich construction, as well as hollow shafts for water or air cooling systems to pass through the encoder.  Because AV125 is super-reliable and features removable sensors, you can install it in hard-to-access configurations and locations without risk of downtime.

Quite simply, the AV125 is designed to eliminate encoder failures:  All AV125 electronics are fully encapsulated.  There are no moving wearing parts. AV125 sensors locate over 4X farther from the rotor than the competition; no more sensor/rotor grinding!  Miswiring an encoder is common – and it shouldn’t cost you time or money. The AV125 has full output short circuit and reverse voltage protection, plus surge protection.

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 AV5 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.

Why risk tiny fragile optical encoders perched precariously behind your large motor or brake. Specify a heavy duty AV125 encoder!
