The A3046EU/LU， A3056EU/LU， and A3058EU/LU Hall effect gear-tooth sensors are monolithic integrated circuits that switch in response to differential magnetic fields created by ferrous targets。 These devices are ideal for use in gear-tooth-based speed， position， and timing applications and operate down to zero rpm over a wide range of air gaps and temperatures。
