Avtron AV30 Absolute Encoders

Absolutely Severe Duty




AV30 shafted magnetic absolute rotary encoders offer a completely new level of durability, never seen before in absolute encoders.  Yet the AV30 encoder will fit existing flanges and mounts, enabling easy upgrades from low durability encoders.   Also available:  hollow shaft model (HS40), absolute+incremental combo units (HS45, AV45) as well as optical models (AV6A, HS6A) for ultra-precision applications.

The AV30 features massive bearings with over 10X the load rating of the competition.  Industry-leading seal systems stay sealed to keep contaminants out, through temperature cycling and liquid sprays.  Moreover, the magnetic sensor can see through oil, dust and dirt that disable ordinary optical absolute encoders.

By utilizing Wiegand wire energy harvesting technology combined with magnetic sensors, Avtron has created an absolute encoder design which requires no batteries, long-term capacitors, glass disks, or gears!

The AV30 features a broad range of industry standard communication protocols:  from analog outputs to CANbus, DeviceNet, J1939 and SSI, you will find the communication protocol you need.
