The differential Hall Effect sensor TLE 4921-3U provides a high sensitivity and a superior
stability over temperature and symmetrical thresholds in order to achieve a stable duty
cycle. TLE 4921-3U 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.
