| Item Description | TMR gear speed sensor / the TMR400X magnetic gear tooth sensors utilize a unique push-pull wheatstone bridge design, including one or two wheatstone full bridges, with four or eight unshielded high sensitivity TMR sensing elements. The wheatstone bridge creates a differential voltage output with respect to the magnetic field gradient along the sensor's sensitive direction. In the dual-bridge configuration, the two orthogonal wheatstone full bridges provide sine and cosine voltage signals that CAN be used to measure both the gear tooth position and the direction of motion. The TMR400X magnetic gear tooth sensors offer superior performance with high sensitivity to the magnetic field gradient. They CAN detect very small changes in magnetic field, along with good temperature stability of the output signal. The TMR400X magnetic gear tooth sensors are available in 6 different standard spacings |
