TT Electronics' MagnePot® 8150 Series family of high-performance multi-turn non-contacting rotary position sensors is designed to operate reliably over a minimum of 10 million shaft rotations with no signal output degradation. They are ideally suited to serve high-reliability markets including industrial, medical and aviation/aerospace.

Overview

The 8150 Series combines the very latest in Hall Effect non-contacting sensing technology and high-performance internal bearing design, resulting in a rotary position sensor with exceptional performance reliability. The non-contacting sensing technology also facilitates clean, ratiometric absolute position outputs across multiple turns without sliding contact noise.

Units are available in a choice of three, five or ten turns, each powered via a 5Vdc supply voltage. The ratiometric output range is from 4% to 96% of supply with a 12mA maximum current rating. MagnePot® 8150 Series models also feature ±0.50% independent linearity as standard, with optional improvement to ±0.25%. Standard operating temperature range is -40oC to +125oC.

Additional 8150 Series device options include alternative output voltages, servo mounts, non-linear outputs, IP50 or IP66 ingress protection, and severe environment versions. Severe service models further incorporate sealed shafts and rear lids. All such modifications and options may be easily accommodated with competitive lead times.

Typical applications for the MagnePot® 8150 Series include industrial joystick controls; factory and laboratory automation; advanced manufacturing; robotic positioning; motion control feedback; medical diagnostic equipment positioning; aircraft flight and panel controls; and vision system positioning feedback.
