Infineon Technologies AG Sensor technology - Magnetic sensors - Magnetic speed sensors - TLE4921-5U TLE4921-5U

XENSIV™ - TLE4921-5U magnetic speed sensor with reduced power consumption

Infineon´s differential Hall effect sensor TLE4921-5U provides a high sensitivity and a superior stability over temperature and symmetrical thresholds in order to achieve a stable duty cycle. TLE4921-5U is particularly suitable for rotational speed detection and timing applications of ferromagnetic toothed wheels such as anti-lock braking systems, transmissions, crankshafts, etc. The integrated circuit (based on Hall effect) provides a digital signal output with frequency proportional to the speed of rotation. Unlike other rotational sensors differential Hall ICs are not influenced by radial vibration within the effective air-gap of the sensor and require no external signal processing.
