Abstract
A position sensor and method include a magnetic component, a first magneto-resistive sensor disposed in proximity to the magnet/coil; and a second magneto-resistive sensor disposed in proximity to the magnetic component and the first magneto-resistive sensor. The first magneto-resistive sensor and second magneto-resistive sensor are configured to sense changes in a stray magnetic field created by the magnetic component in accordance with a relative positional change between the magnetic component and the first and second magneto-resistive sensors.
