ABSTRACT:
Position of a rotatable automotive part is sensed with a trio of magnetic field intensity sensors disposed adjacent a ring that rotates with the automotive part, the ring comprising alternating permanent magnet sections with at least one localized magnetic field depression corresponding to a synchronization position of the part wherein the sensors are spaced along the direction of ring rotation so that the relative phase between the output signals of a first pair of the sensors as indicated by the relative output signal magnitude indicates incremental displacement of the part, and so that a significant difference in magnitude between the output signal of a second pair of the sensors indicates the synchronization position.
