Hall Effect Sensors are sometimes referred to as “switches” rather than sensors because of the on-off “digital” voltage signal they produce. Unlike magnetic sensors that produce an alternating current (AC) signal which varies in voltage with speed, Hall Effec – tSensors produce a constant voltage signal that can change abruptly from maximum voltage to nearly zero and back again regardless of engine speed.This produces a square wave output signal that can be easily used by the onboard computer for timing purposes.
