ABSTRACT:
An electromagnetic actuator assembly with a frame, a movable plunger, first and second sensor targets that are coupled to a plunger for movement therewith, first and second sensors that are coupled to the frame and a controller. The first sensor is configured to sense a position of the first sensor target and to produce a first sensor signal in response thereto. The second sensor is configured to sense a position of the second sensor target and to produce a second sensor signal in response thereto. The controller that receives the first and second sensor signals and identifies three or more discrete points along a path of travel of the plunger. A differential assembly that incorporates the electromagnetic actuator assembly is also provided.
