Inductive speed sensors inductively read gear teeth, pulley bolts or any ferrous metal passing by the sensor. It provides a pulse signal to the ECU which then can be used to either measure Engine speed or Wheel speed.
We use these primarily for non driven wheel speed to implement a Traction Control Strategy.
Kit includes:
1 x Hall effect sensor.
1 x DTM 3pin connector kit.
10ft of m27500 3 core shielded wire.
Most any high quality engine management will support this style of hall sensor.
