What is a magnetic sensor, Magnetic sensors, magnetic sensor, speed detection

The Infineon TLE4972 is a high precision miniature coreless magnetic current sensor for AC and DC measurements with analog interface and two fast over-current detection outputs. The TLE4972 features Infineon's well-established and robust monolithic Hall technology which enables accurate and highly linear measurement of the magnetic field caused by currents. With a full scale up to ±31 mT, it is possible to measure currents up to 2,000 ampere.
