  • SOLENOID SYSTEM WITH AN ARMATURE POSITION SENSOR
    Publication number: 20170133138
    Abstract: A solenoid system for a vehicle can include an electromagnetic device, permanent magnet, and sensor. The electromagnetic device can include a housing, armature, and solenoid to move the armature axially relative to the housing. When the armature is in an extended position, a first end of the armature can extend further in a first direction relative to the housing than when in a retracted position. The sensor can be fixedly coupled to the housing and can detect a magnetic field of a permanent magnet based on the position of the armature.
