Abstract
A method of measuring target proximity comprising the steps of transmitting a magnetic field signal by a controller of a proximity sensor at a target, measuring impedance of an inductor of a proximity sensor, calculating a relative position of the target in relation to a sensor face, and providing a near/far output status of the target at a predetermined rate.
