Claim 16:
17. A rotary sensor for detecting a change in position of a rotary shaft, the rotary sensor comprising:
a sensor housing configured to be secured relative to a mounting environment, the sensor housing defining a cavity;
a sensor disposed within the cavity, wherein the sensor comprises a printed circuit board having an arc shape, wherein the printed circuit board comprises a plurality of sensor elements disposed along an inner circumference of the printed circuit board in a radially outward direction;
a sensor shield defining a slot along a length of the sensor shield, wherein the sensor shield is composed of a highly permeable material and at least a portion of the sensor shield is disposed between the plurality of sensor elements and the mounting environment such that the sensor shield is configured to act as a polepiece that enables a uniform field to be provided to the sensor by isolating the plurality of sensor elements from a magnetic field defined by a ferrous object within the mounting environment;
a bearing disposed within the cavity of the sensor housing, and positioned adjacent to the inner circumference of the printed circuit board; and
the rotary shaft, rotatable about a rotational axis, wherein the rotary shaft is engaged with the bearing, and wherein the sensor housing, the bearing, and the rotary shaft are aligned along the rotational axis.
