Technical Description

The Omron E2E-X3C18 2M Inductive Proximity Sensor is a shielded inductive sensor developed for the detection of metallic objects at a nominal sensing distance of 3 mm. The sensor utilizes an NPN normally open output configuration and operates within a 12 to 24 VDC supply range.

The nickel-plated brass housing provides resistance against vibration, mechanical stress, and industrial contaminants commonly found in manufacturing environments. The integrated LED indicator allows maintenance personnel to verify sensor status during operation and troubleshooting procedures.

The Omron E2E-X3C18 2M Inductive Proximity Sensor is frequently implemented in industrial control systems requiring dependable position sensing and object verification.

Working Principle

Inductive proximity sensors operate by generating a high-frequency electromagnetic field through an internal oscillator circuit. When a conductive metal target enters the sensing zone, eddy currents are induced within the object.

These currents absorb energy from the electromagnetic field, causing measurable changes in the oscillation characteristics. Internal circuitry continuously monitors these variations and changes the output state when the target reaches the specified detection distance.

Because the sensing process does not involve physical contact, wear is minimized and long-term operational stability can be maintained even in high-cycle applications.

Common Usage Areas
