The differential Hall effect sensor TLE 4923 is compatible to the TLE 4921-3U, except
for having a 2-wire interface. The TLE 4923 provides high sensitivity, a superior stability
over temperature and symmetrical thresholds in order to achieve a stable duty cycle.
TLE 4923 is particularly suitable for rotational speed detection and timing applications of
ferromagnetic toothed wheels such as in 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.
