The differential Hall Effect sensor TLE 4921-5U provides a high sensitivity and a
superior stability over temperature and symmetrical thresholds in order to achieve a
stable duty cycle. TLE 4921-5U 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 airgap of the sensor and require no external
signal processing.
