A new generation in sensing
performance!
Producing more than a million per year, Omron is
a world leader in photoelectric sensors. Backed
by more than 40 years of experience, Omron is
constantly enhancing its portfolio and has now
completely redesigned and expanded its popular
M18 cylindrical range. Renowned for its high
quality and product reliability, Omron’s new
generation of photoelectric sensors represents one
of the largest varieties of dependable and easy-to-
use photoelectric sensors on the market. Regardless
of your industry or application, the E3FA series has
the right sensor for the job at the best price versus
performance.

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.
Flush mounting option for smooth installation.Bright LED indicators for the easy operational status checking.
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, retro-
reflective and diffuse reflective types in straight and radial
versions. Straight versions are also available with background-
suppression, limited-reflective detection, and transparent object
detection types for special applications.
All models are available in plastic and metal housing.

E3FA Special Models
The E3FA series includes special models to
solve demanding applications, for example, in
the food and packaging industry.
This includes the detection of
transparent or structured objects.

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.
High power LED to compensate for dirt and misalignment.
Tight housing construction for high-level water protection. Intensive shielding for high electromagnetic noise immunity.
Pulse synchronisation for high ambient light immunity.

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

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