Abstract
Two lines of magnets have the same length and are aligned side by side. The lines of magnets have different numbers of magnetic pole pairs and have equal line lengths. A first sensor determines a relative position between poles of a pole pair of the first line of magnets, and a second sensor determines a relative position between poles of a pole pair of the second line of magnets. A circuit compares the relative positions determined by the sensors to determine an absolute position of the first line of magnets.
