  • System and method for detecting position of a solenoid plunger
    Patent number: 11640864
    Abstract: A solenoid assembly includes a solenoid having a coil that defines a passageway and a plunger movable within the passageway from a retracted position to an extended position. The plunger extends along an axis between a first plunger end and an opposite second plunger end. A frame holds the solenoid and has a first opening through which the first plunger end extends when the plunger is in the retracted position and a second opening through second end of the plunger extends when the plunger is in the extended position. When the plunger is in the extended position the first plunger end retracts into the frame via the first opening.
