The sensor is industrial-grade senor, also named magnetic pick-up or passive speed sensor. As a ferrous object approaches the tip of the pole piece, the magnetic field increases and decreases as the object move away from the pole piece, the snap or the rapid change in the magnetic field induces, an AC voltage signal in the coil, with an ideal target and matching sensor.
