Technical Overview

The Omron E3F1-DP11 2M is a compact, diffuse-reflective photoelectric sensor from the E3F1 Lite Series, featuring a standard M18 threaded cylindrical plastic (ABS) housing. Designed for reliable non-contact part detection, it offers a sensing distance of up to 100 mm and utilizes a bright, high-power red LED (624 nm) light source for easy visual alignment. Operating on a 10 to 30 VDC power supply, it provides a PNP open collector output with selectable Light-ON/Dark-ON functionality. Pre-wired with a 2-meter cable and rated IP66 for ingress protection, the E3F1-DP11 2M is an efficient, cost-effective solution for part presence verification, positioning, and packaging applications in challenging industrial environments.

Industrial Applications

1. Conveyor Line Part Presence Detection

Deployed along automated industrial conveyors to identify the presence of passing parts or cartons within a 100 mm threshold. The standalone diffuse-reflective mechanism detects items directly by reflecting light off the target object, requiring no secondary receiver or reflector.

Problem Solved

Eliminates mechanical wear and prevents surface damage to fragile items associated with physical limit switches, ensuring reliable, high-speed contactless flow monitoring.

2. Automated Assembly End-Position Verification

Mounted within the chassis of automated assembly machines to confirm that mechanical actuators or moving trays have reached their proper home or end positions before the next cycle initiates. The standard M18 cylindrical body simplifies integration into tight mechanical clearances.

Problem Solved

Overcomes spatial constraints and mechanical fatigue issues by providing a high-speed, compact, and non-intrusive alternative to standard mechanical position switches.

3. Packaging Machinery Jam Detection

Positioned at critical transition points in packaging equipment to monitor continuous material flow. The sensor signals the programmable logic controller (PLC) if a product obscures the red LED beam for longer than a predefined duration, indicating a system jam.

Problem Solved

Rapidly identifies packaging bottlenecks, preventing equipment damage and extensive material pile-ups, while the robust IP66 ABS enclosure withstands dusty industrial conditions.
