Working Principle

The Omron E2B-M12KN08-WP-B1 5M Inductive Proximity Sensor generates a high-frequency electromagnetic field at its sensing face. When a metallic object enters this field, electrical eddy currents form within the target material.

The generated currents absorb energy from the oscillator circuit, resulting in a measurable change in oscillation behavior. The sensor electronics continuously monitor these changes and activate the output when the target reaches the sensing threshold.

This process enables fast, repeatable, and contact-free detection without mechanical wear.
