Claim 7:
8. A sensor assembly for a rotary sensor, comprising:
a sensor housing configured to be secured relative to a mounting environment, the sensor housing defining a cavity;
a sensor shield having a first plate and a second plate, the first plate coupled to a first side of the sensor housing and the second plate coupled to a second side of the sensor housing, wherein the sensor shield is composed of a highly permeable material; and
a sensor comprising a printed circuit board having an arc shape, wherein the sensor is disposed within the cavity of the sensor housing, the sensor comprising:
a first array of sensor elements disposed along an inner circumference of the printed circuit board in a radially outward direction, wherein the first array of sensor elements is disposed on a first side of the printed circuit board; and
a second array of sensor elements aligned along the inner circumference of the printed circuit board and disposed on the first side of the printed circuit board;

wherein at least a portion of the sensor shield is disposed between one or more of the first array of sensor elements and the second array 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 one or more of the first array of sensor elements and the second array of sensor elements from a magnetic field defined by a ferrous object within the mounting environment.
