Abstract

In some embodiments, an absolute position sensing system includes a magnetic field sensor and a target structure. The sensor includes an emitting coil configured to generate a magnetic field in response to a current through the emitting coil, a first arrangement of magnetic field sensing elements, and a second arrangement of magnetic field sensing elements. The target structure includes a plurality of coil elements arranged such that, during movement of the target structure relative to the sensor, the emitted field induces a current in different ones of the coil elements resulting in the generation of non-uniform magnetic fields about the first and second arrangements of magnetic field sensing elements. The sensor is configured to process a first signal from the first arrangement of magnetic field sensing elements and a second signal from the second arrangement of magnetic field sensing elements to determine an absolute position of the target structure.
