AV56 THIN-LINE III™ Blade Pitch Encoders set the industry standard for reliable blade pitch controls.

Other THIN-LINE III models, ranging from 115mm to 8.5", are available to fit other motor sizes.

AV56 blade pitch 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 AV56, you know you installed it right: the green LED tells you the digital self-tuning has set your AV56 optimally.  If at any time, the AV56 cannot produce ideal signals, the LED changes to red. Even wiring errors and short circuits are detected and indicated by changing the LED to orange.  However, the encoder keeps working to give you time to schedule service.

With a real-world installation history of over 4,500,000 hour MTBF, and worldwide installation in tens of thousands of wind towers, AV56 blade pitch encoders will keep your machine running 24/7/365!
