Infineon Technologies AG Magnetic position sensors, Magnetic switches TLE4906-3K

XENSIV™ - TLE4906-3K unipolar Hall switch, highly precise for position sensing

The Infineon TLE4906-3K is a high precision Hall effect switch with highly accurate switching thresholds for operating temperatures up to 150°C. Our sensor, TLE4906-3K can be used in all automotive applications which require a high precision Hall switch for position sensing with a operating temperature range from -40°C to +150°C. It is a unipolar Hall switch which is actuated with the south pole of a magnet. A magnetic field above the threshold BOP switches the output to low (output transistor ON) and a magnetic field below the release point BRP back to high (transistor OFF).

Summary of Features
