A3059 Datasheet - Allegro MicroSystems

The UGS3059KA and UGN/UGS3060KA ac-coupled Hall-effect 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.

FEATURES
■ Senses Motion of Ferrous Targets Such as Gears
■ Wide Operating Temperature Range
■ Operation to 30 kHz
■ Resistant to RFI, EMI
■ Large Effective Air Gap
■ 4.5 V to 24 V Operation
■ Output Compatible With All Logic Families
■ Reverse Battery Protection
■ Resistant to Physical Stress
