In an automotive application, which position is detected by an inductive sensor?

The detection of crankshaft position by an inductive sensor is accurate because these sensors function by using the principle of electromagnetic induction to detect the metallic components of the crankshaft as they rotate. When a ferromagnetic object, such as a crankshaft gear or a target mounted on the crankshaft, passes within the sensing range of the inductive sensor, it alters the magnetic field, producing a measurable electrical signal. This signal is used by the vehicle's control systems to determine the exact position of the crankshaft, which is crucial for synchronizing ignition timing, fuel injection, and other engine operations.

In automotive applications, monitoring the crankshaft’s position is essential for optimal engine performance, efficiency, and emissions control, making inductive sensors a suitable choice for this purpose.
