Connector View & Information: -
Cam Shaft Sensor measures the speed of the CAM shaft.
Operating Principle:
Cam shaft Sensor contains a permanent magnet and a Hall IC. Due to the rotation of a ferromagnetic target wheel in
front of Sensor, the magnetic field is modulated at the place of the hall probe. With a tooth in front of the Sensor, the
magnetic field increases, with a slot it decreases. This modulation results in changes of the output signal. The
magnetic field is evaluated by the hall probe in the ASIC.
