1. A sensor assembly for sensing the position of a movable object, comprising:

  • a housing defining first and second cavities;

    a wall separating the first and second cavities;

    a rotor in the first cavity, the rotor including a longitudinal axis and defining a bore and a pocket offset and spaced from the bore and the longitudinal axis of the rotor, the rotor being adapted for coupling with the movable object;

    a magnet in the pocket in the rotor, the magnet being adapted to generate a magnetic field; and

    a sensor in the second cavity, the sensor and the rotor being movable relative to each other and the sensor being adapted to sense the magnetic field and generate an electrical signal that is indicative of the position of the magnet and the position of the movable object.
