Revolution and Timing sensors
Revolution and Timing sensors

These are used in motor vehicles to detect one or more of the following parameters:

  - Rotation speed of the motor shaft (crankshaft rotational speed sensors)

  - Top dead centre, by sensing crankshaft position (crankshaft position sensors)

  - Powering sequence or phase through detection of the camshaft position (camshaft position sensors)

  - Engine or transmission shaft rotation speed and direction (rotational speed and direction detection sensors)

 

These sensors, depending on the technology used, can be of the following types:

  - Reluctance variable (RV)  

-  Digital hall effect (HE) or magneto-resistive sensors (MR or MDR)

  - Toroidal
