Abstract

Magnetic position sensors, systems and methods are disclosed. In an embodiment, a position sensing system includes a magnetic field source; and a sensor module spaced apart from the magnetic field source, at least one of the magnetic field source or the sensor module configured to move relative to the other along a path, the sensor module configured to determine a position of the magnetic field source relative to the sensor module from a nonlinear function of a ratio of a first component of a magnetic field of the magnetic field source to a second component of the magnetic field of the magnetic field source.
