Official Part Number E3FA-TP11 2M
GTIN Standard 4548583440753

Technical Overview

The Omron E3FA-TP11 2M is a high-performance M18 cylindrical through-beam photoelectric sensor. Operating on a 10 to 30 VDC power supply, this robust ABS-housed sensor emits a highly visible 624 nm red LED, ensuring easy alignment and stable detection over a generous 20-meter range. It comes equipped with a 2-meter pre-wired cable, Light-ON/Dark-ON selectable PNP output, and delivers a rapid 0.5 ms response time. Rated IP67 and IP69K, the sensor withstands high-pressure and high-temperature washdowns, making it optimal for rigorous industrial and food processing environments. Superior electromagnetic compatibility (EMC) protection and ambient light immunity further safeguard performance in noisy, bright, or dusty locations.

Key Features

  • Cylindrical M18 ABS plastic threaded housing for standard industrial mounting.
  • Highly visible red LED (624 nm) allowing easy alignment over long distances.
  • Through-beam sensing method capable of reliable detection up to 20 meters.
  • Selectable Light-ON and Dark-ON operation modes with a PNP open-collector output.
  • Pre-wired with a 2-meter cable for immediate integration.
  • Fast 0.5 ms response time for high-speed automated systems.
  • IP67 and IP69K ingress protection, withstanding high-pressure washdowns up to 100 bar at 80°C.
  • Superior electromagnetic compatibility (EMC) and ambient light immunity (up to 10,000 lx sunlight).

Industrial Applications

1. High-Speed Washdown Packaging Lines

Integrating the through-beam sensor into food, beverage, or pharmaceutical packaging conveyors that require frequent, aggressive sanitation processes.

Problem Solved

Standard optical sensors fail due to water ingress during high-pressure cleaning. The IP69K rating of the E3FA-TP11 resists 80°C water jets at 80-100 bar, while its 0.5 ms response time perfectly tracks rapidly moving products without missing counts.

2. Automated Warehouse Pallet Detection

Deploying the through-beam sensor across wide storage aisles, transfer cars, and sorting conveyors to detect large pallets and clear pathways.

Problem Solved

Large warehouses require sensors that can span wide physical gaps and operate without false triggers caused by bright facility lighting or dust. The 20m sensing range and high-power red LED easily punch through dusty air, tolerating up to 10,000 lux of ambient sunlight.

3. Industrial Car Wash Positioning Systems

Utilizing the sensor to accurately detect and position vehicles inside automated drive-through or tunnel car washes before starting the wash cycle.

Problem Solved

Car wash environments feature constant splashing, high-pressure water jets, chemical detergents, and outdoor temperature fluctuations. The ABS housing and IP67/IP69K sealing prevent internal damage, while the -25°C operating limit supports reliable detection across the bay during cold winters.
