Omron E2B-M18LN16-WP-B2 2M Inductive Proximity Sensor

The Omron E2B-M18LN16-WP-B2 Inductive Proximity Sensor is designed for reliable detection of metallic targets in industrial automation systems. Featuring a non-flush M18 cylindrical housing and an extended sensing distance of 16 mm, this sensor supports applications where additional clearance between the sensor and target is beneficial. The device utilizes inductive sensing technology and provides a PNP normally closed output for integration with modern control systems.

Technical Description

The Omron E2B-M18LN16-WP-B2 Inductive Proximity Sensor belongs to the E2B family of industrial sensors developed for stable detection performance in manufacturing and machine automation environments. The sensor incorporates a nickel-plated brass housing that offers mechanical protection while maintaining dimensional stability during long-term operation.

The non-flush design allows the sensing field to extend beyond the face of the sensor, resulting in a greater sensing distance than equivalent flush-mounted models. This characteristic makes the sensor suitable for installations where larger detection gaps are required.

A built-in LED indicator provides visual confirmation of operating status, simplifying commissioning and troubleshooting procedures.

Working Principle

The sensing circuit generates a high-frequency electromagnetic field at the active sensing surface. When a metallic object enters this field, induced eddy currents develop within the target material. These currents absorb energy from the oscillator circuit and create a measurable change in amplitude.

The sensor electronics continuously monitor these changes and activate the output stage when the detection threshold is reached. Because detection occurs without physical contact, the sensing mechanism minimizes wear and supports consistent operation over extended service intervals.

The normally closed output configuration maintains an active signal until a target is detected, at which point the output changes state.

Common Areas of Application
