Abstract
An apparatus having a position sensor for determining a position of a moveable component is provided. The apparatus comprises a housing, a positioning member, a shaped magnetic pole, a magnet, and a hall effect sensor. The positioning member, the shaped magnetic pole, the magnet, and the hall effect sensor are each disposed within the housing. The positioning member is operably coupled to the moveable component and moveable relative to the housing. The magnet induces a magnetic flux in the shaped magnetic pole. One of the shaped magnetic pole and the magnet move in conjunction with the positioning member. The hall effect sensor is adapted to sense an intensity of the magnetic flux in the shaped magnetic pole and generate an output corresponding to the sensed intensity such that the position of the moveable component can be determined.
