Omron E3S-5E4 Photoelectric Sensor – 12-24V DC, 2m Cable

Omron E3S-5E4 Through Beam Photoelectric Sensor | 5 m Detection Range | 2 m Cable

Product Overview

The Omron E3S-5E4 through beam photoelectric sensor is designed for long distance object detection in industrial automation systems. It uses a separated emitter and receiver configuration to detect objects that interrupt the light beam between the two units.

With a maximum sensing distance of 5 meters, the sensor is suitable for conveyor monitoring, packaging systems, automated assembly lines, and material handling equipment.

The unit operates on 12 to 24 V DC power supply, which allows direct integration with PLC control systems and industrial automation controllers. The integrated 2 meter cable simplifies installation and reduces wiring complexity in production environments.

Key Features

Through Beam Detection Method

The emitter and receiver are separated, creating a light beam between the two units. Detection occurs when an object interrupts the beam.

Long Detection Range

Supports object detection up to 5 meters, making it suitable for applications requiring larger sensing distances.

Industrial Power Compatibility

Operates within 12 to 24 V DC supply range, which is commonly used in PLC based automation systems.

Rugged Industrial Design

The housing is designed to withstand vibration, dust, and water spray in manufacturing environments.

Pre Wired Cable

A 2 meter integrated cable allows quick installation without additional connectors.

Technical Specifications

Operating Principle

Through Beam Sensor Working Method

A through beam photoelectric sensor operates using two separate components.

1. The emitter produces a continuous light beam.

2. The receiver detects the light signal.

3. When an object interrupts the beam, the receiver changes its output state.

This detection method provides high accuracy and reduces false triggering caused by reflective surfaces or ambient light.

Typical Industrial Applications

Manufacturing Lines

Used for detecting product presence or part movement on conveyor systems.

Packaging Systems

Helps detect containers, bottles, or packages during filling and sealing processes.

Automated Assembly

Verifies component presence in robotic pick and place systems.

Material Handling

Used for counting, sorting, and positioning objects in transfer systems.

Installation Guidelines

Sensor Alignment

Proper alignment of the emitter and receiver is required for stable detection across the full sensing distance.

Mounting

Sensors are typically mounted using adjustable brackets to maintain beam alignment.

Electrical Integration

The sensor can connect directly to PLC inputs or industrial control systems operating within the 12 to 24 V DC range.

Industrial Advantages

Accurate Object Detection

Through beam sensing reduces interference from reflective surfaces.

Reliable Long Distance Performance

Maintains detection accuracy across distances up to 5 meters.

Easy Integration

Pre wired cable and common voltage requirements simplify installation.

Durable Construction

IP67 rated enclosure protects against dust and water exposure in industrial environments.

Frequently Asked Questions

Can the E3S-5E4 operate on a 24 V DC PLC power supply

Yes. The sensor supports 12 to 24 V DC input, allowing direct connection to standard PLC power rails.

How is the emitter aligned with the receiver

The emitter projects a visible LED beam that helps technicians align the receiver during installation. Adjustable mounting brackets are commonly used to fine tune alignment.

What output types are available

The sensor supports both NPN and PNP outputs, and can be configured as normally open or normally closed depending on system wiring.
