Overview
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.
This differential sensing design provides immunity to radial vibration within the devices’ operating air gaps.
Steady-state magnet and system offsets are eliminated using an on-chip differential band-pass filter.
