Two Hall probes spaced 2.5mm apart detect the differential magnetic field, with an active high-pass filter (external capacitor) removing static offset. The open-collector output provides a digital frequency signal proportional to rotational speed. Protection includes overvoltage, reverse polarity, and output disturbance immunity per ISO 7637.","working_principle":"Two Hall probes detect the differential field from a passing toothed wheel. The differential signal is amplified and filtered through an active high-pass (external capacitor on pin C sets cutoff). A Schmitt trigger converts the filtered signal to a digital output. Dynamic offset compensation eliminates static magnetic field effects.","pin_description":"
