Zusammenfassung:	A displacement sensor includes a magnet assembly having a housing for mounti ng to one of first and second relatively moveable elements. A magnet assembly i s mounted to one element and defines a longitudinal space having an axis along its length. The magnet assembly includes at least one magnet having a north and a south pole that supply fringing magnetic flux in the longitudinal spac e and a flux-shaping pole piece on each of the north and south poles. A magnet ic field sensor assembly has a housing for mounting to the other of the first a nd second elements for movement along an axis in the space parallel to the magn et assembly.
