Abstract
A position sensor is provided for determining the position of a movable member. The position sensor includes a sensor providing an analog output voltage in response to a sensed magnetic field, a magnet located adjacent and in spaced relation to the sensor, and a magnetic field varying member attached to the movable member. The magnetic field varying member includes an outer edge extending to a location axially positioned between the sensor and the magnet, and the magnetic field varying member is movable to vary a magnetic flux between the magnet and the sensor in response to movement of the movable member.
