Abstract
A sensor assembly for measuring linear position is provided. The assembly comprises a ferromagnetic magnetic flux concentrator. The flux concentrator is configured as a generally rectangular structure including an air gap at one side thereof. A magnet is slidable along the longitudinal axis of the concentrator. A galvanomagnetic sensing element is disposed in the air gap for sensing magnetic flux passing therethrough. The sensing element is configured to provide an output signal indicative of the measured linear position as the magnet travels along the longitudinal axis of the concentrator.
