DMCC - DUAL MAG CONVERTER - GEN PURPOSE
A magnetic sensor consists of a wound coil of wire that generates a voltage between the sensor wires when the magnetic field strength changes as the tooth passes the sensor. The output voltage amplitude depends on the gap between sensor and tooth and increases with increased speed past the trigger wheel.
Magnetic sensors may be used if the trigger wheel has a large number of teeth as the sensor has a small magnetic pole size. They are often used as crankshaft or wheel speed sensors.
The sensor may be wired for either a rising or falling waveform by reversing the wires. The ECU should be setup accordingly. The tooth material must be magnetically soft, such as mild steel (do not use stainless steel).
Magnetic sensors must use shielded wire to help eliminate unwanted electrical noise and must be mounted rigidly as any vibration can cause false signals.
