The TMR400X magnetic gear tooth sensor uses a unique push-pull Wheatstone bridge design,inc one or two Wheatstone full bridges,four or eight unshielded high-sensitivity TMR sensing elements. A Wheatstone bridge produces a differential voltage output along the sensor's sensitive direction based on the magnetic field gradient. In a double-bridge configuration,two orthogonal Wheatstone full bridges provide sine and cosine voltage signals that can be used to measure gear tooth position and direction of motion. The TMR400X magnetic gear tooth sensor offers excellent performance with high sensitivity to magnetic field gradients. The TMR400X magnetic gear tooth sensor can detect very small changes in the magnetic field,and the output signal has good temperature stability.,TMR400X magnetic gear tooth sensor has 6 different standard pitches,namely 0.25mm,0.5mm,0.75mm,1.0mm,2.0mm and 3.0mm. Available in two small size LGA packages. Packaging dimensions are 3mm×3mm×0.9mm and 3mm×6mm×0.9mm.,Features and Benefits:,Application:
