Beschreibung
Zusammenfassung:	A magnet assembly is disclosed for use with a magnetic flux sensor to provid e a position sensor adapted to detect a position of a moveable member. The magnet assembly comprises a magnet housing defining an inner surface. A magn et is provided that is sized for insertion into the magnet housing and adapted for movement with the moveable member, the magnet having a north pole and a south pole, wherein the magnet generates a magnetic flux. A centering ring i s positioned between the magnet and the magnet housing, the centering ring including a biased wall acting to center the magnet in the magnet housing.
