DYNAMIC, PEAK-DETECTING, DIFFERENTIAL HALL-EFFECT GEAR-TOOTH SENSORS

The ATS610LSA and ATS611LSB gear-tooth sensors are optimized Hall IC plus magnet modules that provide a user-friendly solution for digital gear-tooth sensing applications. Each module combines in a compact high-temperature plastic package, a samarium-cobalt magnet, a pole piece, and a differential Hall-effect IC that has been optimized to the magnetic circuit. These sensors can be easily used in conjunction with a wide variety of gear or target shapes and sizes.
