It therefore does not reduce the operation rates of production facilities.
The Sensors can accurately detect color marks on glossy and colorful packaging, which have been troublesome for conventional systems.
They also help reduce the number of troubleshooting requests made to packaging machine manufacturers—without any decrease in the operation rate due to equipment stoppages caused by
false detection.

Stable Detection Even of Tilted Workpieces
Thin and soft wrapping paper tends to be difficult to detect stably due to shifting angles. E3S-DC that has OMRON's original narrow beam and large
optical system and E3NX-CA used with the coaxial Fiber Unit make stable detection possible.

The coaxial Fiber Unit E32-C91N has an emission beam that covers a 60° area. Even if the
workpiece is tilted, the Fiber Unit does not receive much of the specular reflected light and
mainly receives diffusion light that carries color information. Therefore it stably detects color
information even if the workpiece has a glossy surface.

From Single Wavelengths to
Color Sensing
The wavelength ranges for red, green, and blue are narrow, and combinations with
other colors cannot be detected with RGB single-color light source sensors (Fig. 2). For
the new Color Mark Sensors, the Photoelectric Sensor uses RGB three-color LEDs as the
light source, and the Fiber Sensor uses a white LED that has a broad wavelength range.
Color sensing makes stable detection possible—even for those color combinations
that would be difficult using single wavelengths.

Visualization of Color Variation
RGB Data Transmission Function
RGB information for color marks and backgrounds for each lot is transmitted to a host and quantified. This information is
then managed in a database, making it possible to set optimal thresholds and identify causes quickly if a problem occurs.
During commissioning
During maintenance
Until now, setting the threshold during commissioning required the knowledge of an expert. Now it is
possible to get the optimal setting just by registering the RGB ratio of the packaging.
When the Sensor makes false detection, values can be checked to determine whether color variation from
lot to lot in packaging material has occurred, making it easy to identify what has caused a problem and to
then resolve it.

Further Information
Test Parameter Support Function *1
The test parameter support function allows users to determine whether or not detection is possible for designs in the prototyping stage. Package designers
and production engineers use quantified RGB digital data to discuss the designs, which allows them to reach a quick decision on which design to use—and
helps shorten lead times from design to production line commissioning.
Examine values that can be detected based on RGB data, then provide feedback on the design.

exceeds the ratings.
4. Do not pull on the cable with excessive strength.
5. Do not attempt to disassemble, repair, or modify the product in
any way.
6. Do not use the product with the main unit damaged.
7. Be sure that before making supply the supply voltage is less than
the maximum rated supply voltage (30 VDC).
8. Do not apply any load exceeding the ratings.
9. Do not short the load. Otherwise damage or fire may result.
10. Connect the load correctly.
11. Do not use the product under a chemical or an oil environment
without prior evaluation.
12. Though this is type IP67, do not use in the water, rain or outdoors.
13. Do not use thinner, alcohol, or other organic solvents. Otherwise,
the optical properties and degree of protection may be degraded.
14. When disposing of the product, treat it as industrial waste.
15. These Sensors are certificated for the UL standard on the
assumption of usage in a Class 2 circuit. Use them with Class 2
power supplies in the United States or Canada. Use the OMRON
XS2F-D4-series or XS5F-D4-series Cables. Cables that have
wires less than AWG24 (0.2 mm2) are for connection to terminal
blocks and are not for field splicing. External overcurrent
protection of 1 A for AWG26, 2 A for AWG24, or 3 A for AWG22
wire must be provided for cable protection.
E3S-DC
6. If a commercial switching regulator is used, ground the FG (frame
ground) terminal.
7. The Sensor will be able to detect objects 100 ms after the power
supply is tuned ON. Start using 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.
8. Do not press the button with anything sharp such as a screwdriver
because it might be damaged.
9. Output pulses may occur when the power supply is turned OFF.
We recommend that you turn OFF the power supply to the load
or load line first.
Precautions for Correct Use
1. Note that the water-resistant function is impaired if installing the
Photoelectric Sensor by hitting it with a hammer and so on.
2. Be sure to tighten the external lens until it reaches the chassis.
3. If the Sensor wiring is placed in the same conduits or ducts as
high-voltage or high-power lines, inductive noise may cause
malfunction or damage. Wire the cables separately or use a
shielded cable.
4. To extend a cable in the standard I/O mode, use a cable of 0.3
mm2 or more and keep the length 100 m or less. Keep the length
20 m or less if using the Sensor in the IO-Link mode.
5. Apply a screw tightening torque of 2.0 N·m or less.

17. UL Standard Certification
Only the Sensors with the Enhanced UL Certification Mark are
certified by UL. They are intended to be supplied by a "Class 2
circuit". When used in United States and Canada, please use the
same Class 2 source for input and output. The overcurrent
protection current rating is 2 A max. They were evaluated as
Open type and shall be installed within a enclosure.
Precautions for Correct Use
1. Be sure to mount the unit to the DIN track until it clicks.
2. When using the Amplifier Units with Wire-saving Connectors,
attach the protective stickers (provided with E3X-CN-series
Connectors) on the unused power pins to prevent electrical shock
and short circuiting. When using Amplifier Units with Connectors
for Communications Units, attach the protective caps (provided
with E3NW-series Sensor Communications Units).

3. Use an extension cable with a maximum length of 30 m. Be sure
to use a cable of at least 0.3 mm2 for extension. The power
voltage must be 24 to 30 V when connecting Amplifier Units with
extension cable and wire-saving connector.
4. Do not apply the forces on the cable exceeding the following
limits:
Pull: 40 N; torque: 0.1 N·m; pressure: 20 N; bending: 29.4 N
5. Use the E32- Fiber Unit.
6. Do not apply excessive force such as tension, compression or
torsion to the Fiber Amplifier Unit with the Fiber Unit fixed to the
Fiber Amplifier Unit.
7. Always keep the protective cover in place when using the
product. Not doing so may cause malfunction.
8. It may take time until the incident level and measurement value
become stable immediately after the power is turned on
depending on use environment.
9. The product is ready to operate 200 ms after the power supply is
turned ON.
10. The Mobile Console E3X-MC11, E3X-MC11-SV2 and E3XMC11-S cannot be connected.
11. The mutual interference prevention function does not work when
in combination with E3C/E2C/E3X.
12. Excessive incident light cannot be sufficiently handled by the
mutual interference prevention function and may cause
malfunction. To prevent this, set a higher threshold level.
13. The Communication Unit E3X-DRT21-S, E3X-CRT, E3X-ECT
and E3NW cannot be connected.
14. If you notice an abnormal condition such as a strange odor,
extreme heating of the unit, or smoke, immediately stop using the
