A non-oriented direct coupled sensor for gear teeth or similarly shaped discontinuities of a ferrous magnetic or magnetic target uses a single magnet and a direct coupled Hall cell integrated circuit to detect the presence or absence of gear teeth. The sensor incorporates techniques for flux steering and flux reversals independent of the orientation of the sensor to the target to overcome the operate or release point of a Hall switch, latch or other device. The use of spaced apart, offset flux concentrators provides a sensitive device with favorable tolerances in temperature and air gap.
