Abstract: The present disclosure relates to an electronic locking differential gear mechanism having a lock detection mechanism for sensing and indication of a locked and unlocked state of the locking mechanism. The electronic locking differential gear mechanism includes an electronic stator which, when activated, rotates a ramped collar about an axis of the mechanism. The ramps of the ramped collar axially displace a plurality of push rods, which displace a locking collar and cause it to engage with a locker gear, placing the mechanism in a locked state. A sensor assembly detects the displacement of a sensing plate which is displaced along with the push rods, and thereby senses whether the mechanism is in a locked or unlocked state.
