Ultraminiature Magnetometer Rotation & Proximity Sensing from NVE 

Tunneling magnetoresistance analog magnetic sensors are revolutionizing sensing capability for product developers. Two new ultraminiature TMR devices from NVE can sense rotation and proximetry with unprecedented precision. One is a dual-axis sensor for sensitive rotation sensing, the other a proximetry sensor that can detect smaller objects at greater distances with more precision than ever before. They expand NVE’s line of ALT-Series TMR analog magnetometers. […]
