ATS665LSG True Zero Speed, High Accuracy, Gear Tooth Sensor
The Allegro ATS665LSG is a true zero-speed gear tooth sensor designed for digital gear tooth sensing applications. It utilizes an optimized Hall IC/magnet configuration packaged in a molded module to provide a user-friendly solution. The sensor incorporates a dual element Hall IC that switches in response to differential magnetic signals created by a ferrous target, offering high accuracy and zero-speed performance independent of air gap.
