Zusammenfassung:A system for reducing stray field effects comprises a magnetic target producing a changing magnetic field; a first set of magnetic field sensing elements placed in spaced relation to the magnetic target and comprising at least a first magnetic field sensing element and a second magnetic field sensing element, each magnetic field sensing element having an axis of maximum sensitivity; a second set of magnetic field sensing elements placed in spaced relation to the magnetic target and comprising at least a third magnetic field sensing element and a fourth magnetic field sensing element, each magnetic field sensing element having an axis of maximum sensitivity; and wherein the first set of magnetic field sensing elements is positioned closer to a center point of the magnetic field than the second set of magnetic field sensing elements.
