AV6A absolute rotary encoders fit industry standard 58mm flanges, yet are superior to ordinary absolute encoders. Also available: HS6A hollow shaft models, AV6M magnetic absolute encoders, AV30 severe-duty absolute magnetic encoders with 58mm, 2.5", and 85mm flange mounting.


AV6A encoders have superior shaft seals and bearings that stay sealed to keep contaminants out, despite temperature cycles or liquid sprays. Our encoder seals are protected by mechanical barriers to prevent flexing or failure. Avtron’s superior bearings permit much larger side and axial loads.


Many competitive optical encoder designs risk sensor damage from any vibration or shock. Some designs even use thin glass disks in "industrial" products! Avtron uses only unbreakable disks.


The AV6A offers a broad range of communication options, from parallel output and SSI to the latest Profibus and Ethernet standards.


Our optical AV6A encoders use superior sensor, disk, bearing, and seal technology to give top performance in industrial conditions. Select an Avtron AV6A today!
