Infineon Technologies TLE4921-5U Magnetic Speed Sensor

Infineon TLE4921-5U Magnetic Speed Sensor provides high sensitivity and superior stability over temperature and symmetrical thresholds. These features provide the ability 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 a 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.
