These parts are in production but have been determined to be NOT FOR NEW DESIGN. The A1688 is a user-friendly, true zero-speed digital ring magnet and gear tooth sensor for two-wire applications. Its UB package integrates an IC and capacitor for enhanced EMC. It features dual Hall elements and sophisticated signal processing for air gap independent switchpoints, and running-mode calibration for environmental immunity.
