B. Working Principle

The OMRON E2B-M18KS08-M1-C1 works on the principle of inductive sensing technology.

The sensor generates a high-frequency electromagnetic field through its sensing coil. When a metallic object enters this sensing field, eddy currents are generated inside the metal target. This changes the oscillation condition of the sensor circuit, which is detected by the internal electronics and converted into an output signal.

The NPN output then switches the connected PLC, controller or automation device based on the detected metal object position.

Working Process:

1. Sensor coil generates an electromagnetic field.
2. Metal object approaches the sensing face.
3. Eddy currents change the electromagnetic field.
4. Internal circuit detects the change.
5. NPN output switches according to the sensing condition.
6. PLC or controller receives the detection signal.

The sensor is designed for detecting ferrous metal objects, with sensing distance depending on target material characteristics.
