AV85A

Heavy Duty, Durable, and Easy to Install

The AV85A THIN-LINE III™ magnetic encoder is engineered for use in heavy mill-duty applications and fits standard 8.5″ C-Face motors and 8.5″ NEMA brake mounting flanges. With a design that ensures easy installation, the AV85 offers exceptional durability and reliability, proven by over 4.5 million hours of Mean Time Between Failures (MTBF) in field installations.

This makes it an ideal choice for brake motor applications, where it is typically mounted between the motor and brake. The encoder features fully potted magnetic sensors that can withstand dirt, liquids, and other contaminants, which are common causes of failure in optical encoders. Unlike traditional encoders, the AV85A has no moving parts, no glass disks, and no optics to clog, ensuring longer life and less maintenance.

Designed with patented Wide-Gap™ Cam Screw Rotors™, the AV85A eliminates sensor damage and simplifies installation, ensuring a secure fit on the shaft. The encoder also features a universal 5-24V design, which allows it to drive longer cables and provides protection against wiring errors and surges.

The built-in digital self-tuning feature, indicated by a green LED light, guarantees optimal performance right from the start. If there are any issues, the LED changes to red, and the remote alarm contact activates, giving you time to schedule maintenance. With its robust construction and clear diagnostics, the AV85A is the ideal solution for ensuring continuous, reliable performance in demanding applications.
