Abstract
In embodiments, three magnetic field sensing elements are arranged equidistantly from each other to define a plane and a central axis perpendicular to the plane. The magnetic field sensing elements are configured to generate a respective output signal representing proximity of a magnetic target that is proximate to the central axis and capable of moving relative to the central axis. A processor circuit is coupled to receive output signals from each of the sensors and configured to calculate a position of the magnetic target relative to the plane.
