The three-pin Hall-effect sensor uses a Hall effect device and a magnet to generate a digital square wave signal (Figure 2)
^
The two-pin Variable Reluctance sensor is a magnetic transducer, which uses differential voltage across windings to generate a voltage waveform
that is similar to a sine wave (Figure 2)
Both sensors provide a switching voltage as the engine rotates.
