Omron E2E-X3D28-R Working Principle

The sensing face generates a high-frequency electromagnetic field. When a metallic object enters the detection zone, eddy currents are induced within the target. These currents absorb energy from the oscillator circuit and alter its operating characteristics.

The internal electronics evaluate these changes and switch the output when the target reaches the specified sensing distance. Because the sensing process does not require physical contact, the sensor avoids mechanical wear associated with conventional limit switches.
