Abstract

A dual-axes position sensor (10) having an outer housing (12), an actuator (40), two Hall effect sensor assemblies (20, 30) for detecting changes along a first (y) and second (x) axis is disclosed. The housing (12) is made of a non-magnetic material. The actuator (40) is rod shaped and coupled to a movable device. The Hall sensor assembly (20) is set on a lip (52) of the housing (12) and includes a pole piece (26) and a magnet assembly (24) having an upper and lower magnet (21, 23) separated by an air gap (25). The two Hall sensor assemblies (20, 30) are positioned 90 degrees from each other.
