Technical Overview

The Omron E3JK-TR11-C 2M is an industrial-grade, long-distance through-beam photoelectric sensor equipped with a built-in AC/DC power supply. It offers an impressive 40-meter sensing range using a high-visibility 624 nm red LED light source. The sensor features a versatile relay output (SPDT, Light-ON/Dark-ON selectable) and comes pre-wired with a 2-meter cable. Encased in a rugged ABS housing with an IP64 rating, it is designed for reliable object detection across wide conveyor lines, automated gates, and heavy-duty manufacturing environments where wide voltage tolerances and robust environmental resistance are required.

Key Features

Industrial Applications

1. Wide-Span Conveyor Jam Detection

Monitoring extremely wide conveyor belts in lumber or automotive manufacturing facilities where the emitter and receiver must be spaced far apart. The 40-meter through-beam range easily covers broad spans, while the universal AC/DC power allows direct integration into existing high-voltage AC facility control panels.

Problem Solved

Overcomes the range limitations of standard sensors on extra-wide material handling lines, and eliminates the need to install separate 24VDC power supplies for sensor networks.

2. Automated Facility Gate and Access Control

Detecting vehicles and large objects across automated factory gates, loading docks, or parking barriers. The IP64-rated ABS housing and -25 to +55 degree Celsius operating range ensure reliable semi-outdoor operation, while the red LED allows quick alignment across long driveways.

Problem Solved

Provides a robust, weather-resistant optical barrier to prevent automated gates from closing on personnel or heavy trucks, ensuring safety and access automation.

3. Heavy Machinery Perimeter Alert System

Serving as a non-safety perimeter object detection system around moving heavy machinery such as gantry cranes. The sensor's built-in 3A relay output can directly switch high-voltage alarm horns or warning lights.

Problem Solved

Significantly reduces wiring complexity and hardware costs by allowing the sensor to directly actuate a heavy-duty warning circuit without needing an interposing PLC or external relays.
