General Description

The MMGX45 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.
