XENSIV™ TLE4966-2K Hall magnetic switch with high sensitivity and highly stable switching points TLE4966-2K is a dual Hall-effect sensor IC designed for high-precision applications, achieving precise magnetic switching points and temperature stability through active compensation and chopper techniques. It provides two independent speed outputs at Q1 and Q2, with status corresponding to the magnetic field value. The spatial distance of the two Hall elements creates a phase difference when used with a rotating magnetized pole wheel.
