Omron E3S-CL2 2M Distance-Settable Photoelectric Sensor

Model Identifier E3S-CL2 2M
Official Part Number E3S-CL2 2M
GTIN Standard NA

Technical Overview

The Omron E3S-CL2 2M is an industrial-grade photoelectric block sensor featuring advanced background suppression (BGS) and distance-setting capabilities. Equipped with an infrared LED light source, it reliably detects objects within an adjustable range of 5 mm to 500 mm, virtually eliminating false triggering from backgrounds. The sensor is engineered with a rugged zinc die-cast housing and a methacrylate resin lens, offering IP67-rated ingress protection and high oil resistance for demanding environments. With a rapid 2 ms response time and dual NPN/PNP digital outputs, it ensures precise integration into high-speed automation systems.

Industrial Applications

1. CNC Machining Workpiece Detection

In heavy-duty CNC milling centers where cutting fluid is highly prevalent, reliably verifying metal part positioning is challenging. The sensor's zinc diecast housing and oil-resistant cord perform excellently in this environment, while the background suppression correctly identifies the part up to 500 mm away without triggering on reflective machine walls or fluid splashes.

Problem Solved

Eliminates sensor degradation from cutting fluids and prevents false triggering caused by shiny machine backgrounds or coolants.

2. Mixed-Color Packaging Conveyor Lines

In secondary packaging systems, boxes passing on a conveyor frequently vary in size, color, and surface reflectivity. The distance-settable infrared beam strictly detects presence within the 500 mm threshold, completely ignoring the conveyor guide rails moving directly behind the target.

Problem Solved

Prevents varying packaging colors and graphical prints from causing missed detection or double-triggering common in standard diffuse sensors.

3. Automated Washdown Material Handling

Used in material handling sections of food or beverage processing lines where machinery requires frequent cleaning. The sensor's robust NEMA 4X/6P and IP67 construction stands up to rigorous environments while its 2ms response time seamlessly synchronizes downstream high-speed sortation.

Problem Solved

Solves the issue of photoelectric sensor failure in high-humidity/washdown cycles while maintaining rapid 2 ms timing for high-speed sortation.
