Abstract
The present invention relates to sensing engaged/disengaged modes of an electromagnetic actuator assembly, such as can be used in a locking differential or other locking gearset. Described herein is a sensor for sensing such engagement/disengagement and methods of using such a sensor. The sensor has a magnet having a north and south pole, a Hall element, and a ferrous target, wherein the ferrous target moves relative to the Hall element and magnet as a result of a position of the locking gearset.
