Abstract
A rotary position sensing including a first and second magnet spaced from one another. A first and second triangular magnetic flux director are arranged in a generally diamond shaped configured with an air gap between the two magnetic flux directors. A magnetic field sensor system is positioned in the air gap between the magnetic flux directors. The magnets and the magnetic flux directors, with the magnetic field sensor system in the air gap, are rotatable relative to one another about an axis generally normal to a plane including the magnets and magnetic flux directors. The magnetic field sensor system provides an output in response to a rotational position of the magnets relative to the magnetic flux directors.
