Abstract
A system for detecting a magnetic target includes a magnetic field sensor comprising two or more sensing clusters positioned on a surface of a substrate; and a magnetic target comprising at least four magnetic quadrants spaced evenly around a center point of the magnetic target. The at least four magnetic quadrants have alternating magnetic polarities. The two or more sensing clusters are positioned evenly around the axis of rotation so that each of the sensing clusters detects a magnetic field of two magnetic quadrants that have the same magnetic polarity.
