NVE Introduces Tunneling Magnetoresistance Gear-Tooth Sensors

NVE introduced the world’s first practical non-inductive gear-tooth sensors 25 years ago and is shaking up the market again with the world’s first tunneling magnetoresistance (TMR) gear-tooth sensors. With two channels to detect direction, the new ABT-Series Gear-Tooth Sensors are versatile analog sensors, typically used with back-biasing magnets to encode the position of a ferrous gear. 

Able to resolve angles as fine as 0.001 degrees, they are suited for a variety of applications including motion, speed and position sensing, also linear and rotational encoders, closed-loop servo systems, machine tools and automotive sensors. There are four models in the ABT Series, matching a wide range of gear pitches from 0.6 millimeters to 4.8 millimeters. 

Based in Eden Prairie, Minnesota, NVE is a leader in the practical commercialization of spintronics, a nanotechnology that relies on electron spin rather than electron charge to acquire, store and transmit information. The company manufactures high-performance spintronic products including sensors and couplers that are used to acquire and transmit data. For more info, see www.nve.com
