Dual-channel dynamic differential Hall sensor circuit Your current location:Home > Products > Dual-channel dynamic differential Hall sensor circuit

Based on the working principle of the Hall effect, the strength and direction of the bias magnetic field passing through the Hall integrated circuit will change with the changing position of the tooth tip and tooth valley (tooth gap) of the moving gear, so that the difference of the magnetic field signal sensed by the two differential Hall sensors becomes a differential voltage signal. After filtering, amplificating and adaptive comparison, the weak voltage signal is transformed into a differential voltage signal. Trigger the switching unit circuit inside the circuit to open and close the action, so the output end of the circuit produces a high and low level digital signal corresponding to the shape of the gear. The dual-channel dynamic differential Hall sensor circuit contains two sets of such differential Hall channels, so that two sets of orthogonal signals can be output at the same time.
Typical characteristics:Differential Hall sensor structure, high sensitivity, double channel orthogonal output, wide range of effective detection distance, strong anti-jitter ability, not easy to misoperate.
Typical applications:Camshaft sensors, crankshaft sensors, tachometers and counters.
