Overview: ATS610LSC DYNAMIC, PEAK-DETECTING, DIFFERENTIAL HALL-EFFECT GEAR-TOOTH SENSOR ATS610LSC
The ATS610LSC gear-tooth sensor is an optimized Hall IC plus magnet subassembly that provides a user-friendly solution for digital gear-tooth sensing applications. The subassembly bines in a pact high-temperature plastic shell, a samarium-cobalt magnet, a pole piece, a differential Hall-effect IC that has been optimized to the magnetic circuit, and a voltage regulator. The sensor can be easily used in conjunction with a wide variety of gear or target shapes and sizes. The ATS610LSC is designed to provide increased immunity to false switching in applications that require the sensing of large-tooth gears (e.g., crank angle or cam angle). The sensor subassembly is ideal for use in gathering speed, position, and timing information using gear-tooth-based configurations.

(subject to change without notice) The gear-sensing technology used for this sensor plus magnet subassembly is Hall-effect based. The sensor incorporates a dual-element Hall IC that switches in response to differential magnetic signals created by the ferrous target. The circuitry contains a patented track-and-hold peak-detecting circuit to eliminate magnet and system offset effects. This circuit has the ability to detect relatively fast changes, such as those caused by gear wobble and eccentricities, and provides stable operation at extremely low rotation speeds.
