Omron E2E-X3D28-R 5M Inductive Proximity Sensor

Long cable runs are common in industrial facilities where control panels and sensing points are separated by considerable distances. The Omron E2E-X3D28-R Inductive Proximity Sensor addresses this requirement by combining compact sensing capabilities with a factory-installed 5-meter cable, reducing the need for additional extension wiring in many machine designs.

As a member of the E2E NEXT family, the Omron E2E-X3D28-R Inductive Proximity Sensor is engineered for non-contact metallic object detection in industrial automation systems. Its shielded sensing structure, durable metal housing, and advanced environmental protection ratings make it suitable for demanding production environments.

Technical Description

This sensor is designed to detect metallic targets through inductive sensing technology. The compact M8 housing allows installation in equipment where available mounting space is restricted while maintaining a sensing distance of 3 mm.

• M8 threaded cylindrical body
• 3 mm sensing distance
• Normally Closed switching operation
• 2-wire DC output design
• Factory-installed 5-meter cable
• Shielded sensing structure
• Nickel-plated brass housing
• IP67, IP67G, and IP69K protection ratings

Working Principle

The sensor continuously generates an electromagnetic field from its sensing surface. When a conductive metal target enters the detection zone, eddy currents are induced within the target material. These currents influence the internal oscillator circuit.

The sensor electronics monitor these changes and trigger an output transition once the target reaches the rated sensing range. Since no physical contact occurs during detection, the sensing process minimizes mechanical wear and supports long-term operational reliability.

Common Usage Areas

The compact housing and extended cable length support installation across a broad range of automation systems.

• Industrial conveyors
• Automated production equipment
• Packaging machinery
• Warehouse automation systems
• Material handling installations
• Machine tool equipment
• Assembly lines
• Industrial robotics
