Technical Overview

The Omron E3S-DCP21-IL2 is a high-performance diffuse-reflective color mark photoelectric sensor with a built-in amplifier. Utilizing an advanced RGB (Red/Green/Blue) light source, it excels at distinguishing slight color differences and detecting challenging registration marks on various packaging types, even when workpieces are tilted. Equipped with IO-Link V1.1 communication, it offers seamless integration, remote configuration, and real-time diagnostics for smart industrial applications.

Key Features

  • Advanced RGB light source (635 nm Red, 525 nm Green, 465 nm Blue) for precise color mark detection.
  • Ultra-fast 50 µs response time for high-speed applications.
  • Narrow beam with a 1 × 4 mm spot size and large lens for stable detection of tilted workpieces.
  • Built-in IO-Link V1.1 (COM2 at 38.4 kbps) for easy configuration and condition monitoring.
  • Selectable Push-Pull digital output (NO/NC operation modes).
  • Robust IP67-rated nickel-plated brass housing suitable for harsh industrial environments.

Operates on 10 to 30 VDC (±10%) with a maximum power consumption of 960 mW, featuring built-in reverse polarity and output short-circuit protection.

Industrial Applications

1. High-Speed Packaging Registration Mark Detection

Detects printed registration marks on fast-moving continuous webs of plastic film, paper, or foil to trigger precise cutting or sealing operations.

Problem Solved

Eliminates misaligned cuts and packaging waste by accurately detecting low-contrast color marks at extremely high production speeds.

2. Automated Component Sorting by Color Coding

Identifies and sorts manufactured parts or boxed goods on a conveyor line based on subtle RGB color codes printed on the items.

Problem Solved

Replaces manual visual inspection and minimizes sorting errors for products that have identical shapes but differ only by subtle color markings.

3. Label Verification on Tilted Containers

Verifies the presence and correct placement of color labels on bottles or irregular containers moving through a filling line, even if they wobble or tilt slightly.

Problem Solved

Ensures reliable quality control in bottling and packaging lines where standard optical sensors fail due to glare or varying angles of the target surface.
