Omron E2B-M12LS04-M1-B1-20 Inductive Proximity Sensor

Technical Overview

The Omron E2B-M12LS04-M1-B1-20 Inductive Proximity Sensor is designed for non-contact detection of metallic targets in industrial automation environments. It belongs to the E2B sensor family, which is commonly used in machine control systems, material handling equipment, assembly stations, and industrial production lines.

This sensor features an M12 cylindrical housing with a shielded sensing face and a sensing distance of 4 mm. The nickel-plated brass body provides mechanical durability while maintaining resistance against industrial contaminants and routine environmental exposure.

The Omron E2B-M12LS04-M1-B1-20 Inductive Proximity Sensor uses a PNP normally open output configuration and supports operation from a DC power supply. Its M12 connector simplifies installation and replacement during maintenance activities.

How the Sensor Works

Inductive proximity sensors operate by generating an electromagnetic field at the sensing face. When a conductive metallic object enters this field, eddy currents are induced within the target material.

These currents cause changes in the oscillation characteristics of the sensor’s internal circuit. Once the change reaches a predefined threshold, the sensor output switches state and sends a signal to the connected controller, PLC, or automation device.

Because detection occurs without physical contact, mechanical wear is minimized and long-term operational consistency can be maintained.
