## **Features** 

## **Simplicity** 

Omron’s compact E3FA series of photoelectric sensors is simple and quick to mount, as well as easy and intuitive to set-up. The large and robust adjuster makes life much easier for installers to adjust the sensor, as does the bright, high-power red LED, which is clearly visible for easy alignment, even over longer distances. Similarly, the sensor’s LED status indicator can be viewed from long distances and wide angles. 

Compact size and shape. Can be installed almost anywhere. 

## **One family for all** 

Visible LED light for easy alignment. 

Bright LED indicators for the easy Flush mounting option for smooth inoperational status checking. stallation. 

## **Application specific models** 

Typically installed in industrial plants ranging from food and beverage, textiles, ceramics and brick production, through to logistics, there’s always an E3FA model to fit your application. 

This extensive photoelectric sensor series with high reliability and enhanced performance includes through-beam, retroreflective and diffuse reflective types in straight and radial versions. Straight versions are also available with backgroundsuppression, limited-reflective detection, and transparent object detection types for special applications. 

Limited-reflective types suitable Transparent object detection Background suppression types for detecting transparant film to types utilising Omron’s unique for the stable detection of differshiny, mirror film. technology for detecting objects ent objects with various colours. with birefringent (double refraction) properties. 

## **Non-stop detection** 

Especially designed for machines that never stop, the rugged E3FA series offers completely reliable sensing in a robust and waterproof housing that can withstand even high-pressure cleaning. Exceeding market standards, this series also has high EMC protection and light immunity. In addition, there is the added benefit of the high-power LED, which contributes to high sensing stability even in environments with dust or vibrations.

* IP69K Degree of Protection Specifications IP69K is a protection specification stipulated by DIN 40050 Part 9 of the German standards. 

The test item is sprayed with 80 ° C water from a nozzle of a specified shape at a water pressure of 80 to 100 bar. The amount of water is 14 to 16 liters per minute. 

The distance between the test item and the nozzle is 10 to 15 cm. The water is discharged at angles of 0 ° , 30 ° , 60 ° , and 90 ° from the horizontal plane for 30 seconds at each angle while the test item is rotated horizontally.

## **Safety Precautions** 

## **Refer to** _**Warranty and Limitations of Liability**_ **.** 

## **WARNING** 

**This product is not designed or rated for directly or indirectly ensuring safety of persons. Do not use it for such a purpose.** 

5. Do not use the sensor under the environment under the other conditions in excess of rated. 

6. Do not use the sensor in place that is exposed by direct sunlight. 

7. Do not use the sensor in place where the sensor may receive direct vibration or shock. 

8. Do not use the thinner, alcohol, or other organic solvents. 

9. Never disassemble, repair nor tamper with the sensor. 

## **CAUTION** 

**Never use the product with an AC power supply. Do not use the product with voltage in excess of the rated voltage.** 

**Do not use the product with incorrect wiring. Otherwise, explosion, fire, malfunction may result.** ~~nr.~~ 

## **Precautions for Safe Use** ~~|~~ Be sure to follow the safety precautions below for added safety. 

1. Do not use the sensor under the environment with explosive, flammable or corrosive gas. 

2. Do not use the sensor under the oil or chemical environment. 

3. Do not use the sensor in the water, rain or outdoors. 

4. Do not use the sensor in the environment where humidity is high and condensation may occur. 

- 10.Please process it as industrial waste. 

## **Precautions for Correct Use** ~~|~~ 

1. Laying Sensor wiring in the same conduit or duct as high-voltage wires or power lines may result in malfunction or damage due to conduit or use shielded cable. 

2. Do not pull on the cable with excessive force. 

3. If a commercial switching regulator is used, ground the FG (frame ground) terminal. 

4. The sensor will be available 100 ms after the power supply is tuned ON. Start to use the sensor 100 ms or more after turning ON the power supply. If the load and the sensor are connected to separate power supplies, be sure to turn ON the sensor first. 

5. Output pulses may be generated even when the power supply is OFF. Therefore, it is recommended to first turn OFF the power supply for the load or the load line. 

6. The sensor must be mounted using the provided nuts. The proper tightening torque range of E3FA/E3RA plastic housing series is between 0.4 and 0.5 N•m. The proper tightening torque of E3FB/ E3RB metal housing series is 20 N•m max..
