3059 AND 3060 HALL-EFFECT GEAR-TOOTH SENSORS —AC COUPLED
3059 AND 3060
The UGN/UGS3059KA and UGN/UGS3060KA ac-coupled Halleffect gear-tooth sensors are monolithic integrated circuits that switch in response to changing differential magnetic fields created by moving ferrous targets. These devices are ideal for use in non-zero-speed, gear-tooth-based speed, position, and timing applications such as in anti-lock braking systems, transmissions, and crankshafts. Both devices, when coupled with a back-biasing magnet, can be configured to turn ON or OFF with the leading or trailing edge of a gear-tooth or slot. Changes in fields on the magnet face caused by a moving ferrous mass are sensed by two integrated Hall transducers and are differentially amplified by on-chip electronics.
