Magnetic Speed Sensors

Two-Wire True Zero Speed Miniature Differential Peak-Detecting Gear Tooth Sensor IC with Continuous Calibration

ATS642

These parts are in production but have been determined to be NOT FOR NEW DESIGN. The ATS642 is an optimized Hall IC for true zero-speed digital gear-tooth sensing in two-wire applications. It features a dual-element sensor and sophisticated digital processing for air-gap independent switchpoints and running-mode calibration, providing speed and duty cycle information, ideal for ABS.
