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.
Visible LED light for easy alignment.
One family for all
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.
Bright LED indicators for the easy
operational status checking.
Flush mounting option for smooth installation.
Application specific models
Limited-reflective types suitable
for detecting transparant film to
shiny, mirror film.
Transparent object detection
types utilising Omron’s unique
technology for detecting objects
with birefringent (double refraction) properties.
Background suppression types
for the stable detection of different objects with various colours.
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 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.

* 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.
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.
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.
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.
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..
