SKU: Omron-E3JK-DR11-C
Price: 36.11 USD
Availability: InStock

Technical Overview

The Omron E3JK-DR11-C 2M is a heavy-duty photoelectric sensor featuring a built-in power supply capable of operating on universally selectable 24 to 240 VDC or 24 to 240 VAC lines. It utilizes a diffuse-reflective sensing method powered by a highly visible red LED (624 nm) with an extended sensing distance of 2.5 meters. The robust ABS housing carries an IP64 rating and includes an SPDT relay output (250 VAC, 3A max) with selectable Light-ON/Dark-ON operation. Pre-wired with a 2-meter PVC cable and shipped with a mounting bracket, it is engineered for easy installation in harsh industrial and legacy automated environments.

Industrial Applications

1. Conveyor Belt Large Object Detection

In heavy-duty packaging and logistics facilities, variable power supply lines (e.g., legacy 120VAC or modern 24VDC) are used across long distances. This sensor easily handles object detection of large pallets or boxes across conveyor widths up to 2.5 meters without needing specialized low-voltage DC power drops.

Problem Solved

Eliminates the need for separate low-voltage DC power supplies on legacy AC-powered conveyors while reliably detecting non-reflective packages at extended distances up to 2.5m.

2. Industrial Bay Door Automation

Automated bay doors in warehouses face environmental extremes and require reliable presence detection before closing to prevent vehicle or personnel accidents. The broad voltage capability allows direct connection to existing high-voltage door controller power.

Problem Solved

Prevents automated warehouse doors from closing on forklifts or personnel by using its long-range 2.5m diffuse reflection and high-visibility red LED spot for easy alignment across wide doorways.

3. Legacy Factory Automation Retrofitting

When modernizing old manufacturing lines, engineers often face mixed AC and DC control voltages without a standardized PLC. This photoelectric sensor integrates seamlessly as a direct relay switch to automate machine start/stop processes when parts pass through the assembly zone.

Problem Solved

Solves the incompatibility issue of retrofitting modern sensors into legacy machine panels by providing direct wide-range AC/DC input and a mechanical relay output that can switch heavy loads directly.
