- Mill Duty
- Wide-Gap Technology: Up to 8X larger gap between sensor and rotor
- Up to 2500 PPR
- No couplings required
- Heavy duty bearings and seals
- Rugged cast housing
- Dust and liquid tight
- Available in thru shaft and end of shaft models
- Fits large motor and load shafts directly
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.
Forget tiny hollow shaft encoders that require shaft reduction and special protection! M3 mill duty encoders can accommodate up to a 2 3/8" shaft directly and are designed for use in rougher applications than ordinary optical encoders.
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. When you install an Avtron M3, you’ve upgraded to the most durable optical encoder available anywhere!
Also available: Heavy mill duty HS45 and severe duty AV685 encoders.
