Crank, Cam & Speed
Hall sensors contain a semiconductor Hall effect integrated circuit (IC) and a magnet. There are Hall sensor types available that can be used with a tooth (gear) style trigger wheel for measuring crank angle or wheel speed, and types that use a vaned rotor passing through a Hall sensor gap.
The IC detects changes in the field strength as the vane passes through the sensor gap or a tooth passes the sensor tip. The output voltage changes from low to high (or high to low) when the leading edge of the tooth passes the centre of the sensor.
The vane or tooth material must be magnetically soft, such as mild steel—do not use stainless steel.
