Abstract
A sensing apparatus includes first and second magnet assemblies. The first magnet assembly includes first and second magnets that have respective first and second opposite magnetic fields. The first magnet has a plurality of dimensions including an inner circumferential dimension, an outer circumferential dimension, an inner axial dimension, an outer axial dimension, and a radial dimension, and the second magnet has a corresponding plurality of dimensions. The inner circumferential dimension or outer circumferential dimension of the first magnet is relatively smaller than the corresponding dimension of the second magnet. A second magnet assembly is positioned at a distance from the first magnet assembly and includes a third magnet having a third magnetic field opposite to the first magnetic field. The first magnet assembly is a high-resolution track, and the second magnet assembly is a low-resolution track.
