An actuator assembly including a housing. The housing having an actuator component, an armature, and at least a portion of a sensor disposed therein. The armature is selectively positionable between a first position and a second position. The sensor includes at least one sensing element disposed within the housing adjacent to the armature. The sensing element has a physical property which varies based upon a position of the armature within the housing.

1. A system for a vehicle, comprising: a pressure plate configured to lock a differential; andan actuator assembly, comprising: a housing;an actuator coil disposed within the housing;an armature disposed within the housing, the armature selectively positionable between a first position and a second position to actuate the pressure plate;a sensor including a first sensing element, wherein a physical property of the first sensing element varies based upon a position of the armature or pressure plate, wherein the sensor is not a full disc; anda controller in electrical communication with the sensor, the controller coupled with a portion of the housing and extending radially outward past an outermost radial surface of the housing, wherein the controller extends toward a central axis of the actuator assembly radially inward past the outermost radial surface of the housing. 2. The system according to claim 1, wherein the sensor is an eddy current sensor. 3. The system according to claim 1, wherein the armature is an annular. 4. The system according to claim 1, further comprising the differential, the differential housed in a differential case. 5. The system according to claim 1, wherein the first sensing element is disposed between the armature and housing. 6. The system according to claim 1, wherein the first sensing element is disposed between the armature and the actuator coil. 7. The system according to claim 1, wherein the first sensing element is disposed in a recess formed in the housing. 8. The system according to claim 1, further comprising a second sensing element disposed within the housing adjacent to the armature. 9. The system according to claim 8, wherein the sensor includes an array of at least one of the first sensing elements and the second sensing elements. 10. The system according to claim 8, wherein a physical property of the second sensing element varies based upon a position of the armature. 11. The system according to claim 10, wherein the physical property of at least one of the first sensing element and the second sensing element is inductance. 12. The system according to claim 1, wherein the first sensing element is a coil. 13. An axle assembly for a vehicle, comprising: an axle shaft;an electric motor coupled with a power source;a differential assembly; andan inverter, wherein the axle assembly has a co-axial or off-axis layout where the axle shaft connecting a wheel to the differential assembly does not pass through a center of the electric motor but rather parallel to a motor axis,the differential assembly including: a pressure plate configured to lock a differential; andan actuator assembly, comprising: a housing;an actuator coil disposed within the housing;an armature disposed within the housing, the armature selectively positionable between a first position and a second position to actuate the pressure plate;a sensor including a first sensing element, wherein a physical property of the first sensing element varies based upon a position of the armature or pressure plate, wherein the sensor is not a full disc; anda controller in electrical communication with the sensor, the controller coupled with a portion of the housing and extending radially outward past an outermost radial surface of the housing, wherein the controller extends toward a central axis of the actuator assembly radially inward past the outermost radial surface of the housing. 14. The axle assembly according to claim 13, wherein the sensor is an eddy current sensor. 15. The axle assembly according to claim 13, wherein the armature is an annular. 16. The axle assembly according to claim 13, wherein the first sensing element is disposed between the armature and housing.
