A19303 - Allegro

A19303 Hall-Effect Wheel Speed and Direction Sensor

The A19303 is an optimized Hall-effect integrated circuit (IC) with PW and AK Protocol that provides a user-friendly two-wire solution for applications where pitch accuracy is important for the determination of speed and direction of the sensed target. The small package includes an integrated capacitor and Hall-based IC in a single overmolded design, with an.
