MMGX45 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 fiel.
