XENSIV™ - TLE4966-2K magnetic switch offers high sensitivity and high stability of the magnetic 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.
