AV85 (THIN-LINE III™) Magnetic Encoder

AV85 THIN-LINE III™ heavy mill duty modular magnetic encoders fit standard 8.5" C-Face motors and 8.5" flanges commonly used for NEMA brake mounting. Other THIN-LINE III models, ranging from 115mm to 6.75", are available to fit other motor sizes, and AV125 is available for 12.5" NEMA brake applications.

The AV85 is perfect for brake motor applications where the encoder is sandwiched between the motor and brake.  With a real-world installation history of over 4,500,000 hour MTBF, you don't have to worry about replacing the encoder!

THIN-LINE III encoders feature simple installation, durable construction, and clear diagnostics to eliminate encoder-related downtime: First, the magnetic sensors are fully potted to withstand dirt and liquids.  No glass disks, no optics to clog. There are no moving, wearing parts!  The patented Wide-Gap™ Cam Screw Rotors™ put an end to sensor damage, are simpler to install, and stay securely mounted to the shaft.  The universal 5-24V design drives longer cables and is protected against wiring errors and surges.  When you power up an AV85, you know you installed it right: the green light tells you the digital self-tuning has set your AV85 optimally.  If at any time the AV85 cannot produce ideal signals, the LED changes to red and the remote alarm contact activates.  However, the encoder keeps working to give you time to schedule service.  Any time there are wiring errors, the LED changes to orange.  AV85 is the ideal solution to keep your motor and drive system running 24/7/365!
