Avtron M3 Optical Incremental Encoder

Avtron M3 large bore hollow shaft mill duty optical hollow shaft encoders fit motor or load shaft from 1 1/2" to 2 3/8" [48mm-60mm].

Looking for solid shaft M3-1 and M3-2 models or small-bore M3 models?  Use our cross reference page to replace these models with the latest Avtron models.

M3 has bigger bearings than light duty and commercial grade encoders to withstand more shaft vibration and stress. M3 encoders are designed with bigger, heavy-duty seals to keep contamination out of the encoder and keep your machines working.

M3 encoders offer a large variety of connector and mounting options to replace virtually any existing encoder or tachometer.
