1. A differential assembly comprising:
a) a first housing;
b) a first half-axle output;
c) a second half-axle output;
d) a power input location;
e) a gear set disposed within the first housing and operably connecting the first half-axle output, the second half-axle output, and the power input location together;
f) an electrically activated locking assembly including a second housing mounted to the first housing and being operable between a locked position, in which the first and second half-axle outputs are prevented from rotating relative to each other, and an unlocked position, in which the first and second half-axle outputs are enabled to rotate relative to each other, the locking assembly including a first pair of anti-rotation members extending from the second housing;
g) a sensor assembly including a position sensing plate defining a first axially extending tab supporting a sensor target of a position sensor, the position sensing plate being coupled to the locking assembly such that operation of the locking assembly between the locked and unlocked positions causes axial movement of the position sensing plate, the first axially extending tab being located between the first pair of anti-rotation members such that the position sensing plate is non-rotatable with respect to the second housing, the position sensor being configured to measure an axial position of the position sensing plate.
