Differential having armature position detection

A position detection device configured for use with a locking differential, the position detection device configured to determine a position of an armature in relation to a stator, the stator having a primary coil that comprises an outer diameter and defines a primary coil axis, the armature moving relative to the stator between engaged and disengaged positions corresponding to the locking differential being in a locked and unlocked state, the position detection device comprising:

• only a single secondary coil disposed proximate to the primary coil and radially disposed within the outer diameter of the primary coil, wherein the secondary coil defines a secondary coil axis;
• and
• wherein the secondary coil is positioned such that the primary and secondary coil axes are offset and parallel, the secondary coil configured to determine a change in inductance based on movement of the armature, the change in inductance indicative of a change in position of the armature relative to the stator, wherein the primary coil is disposed within a first boundary of the stator and wherein the secondary coil is disposed within a second boundary of the primary coil.
