Color Sensing
New Model with Four-color Determination for Even
More Complete Color-sensing Fiber Sensors

The color-sensing engine uses three parameters, RGB, to process
incident light. It detects color information from the workpiece for precise
detection of color differences.
Changes in the three parameters are processed as a ratio, so they are
not affected by light-intensity variations due to workpiece movement.

Easy and Reliable ...Ease of Use and Smart Functions
In addition to ensuring easy use, we have added a number of smart
functions, such as remote control to simplify setup, and twin
sensing and output to simultaneously distinguish two registered
colors.(advanced models)
Amplifier Unit
A Slim, 10-mm-wide Amplifier Unit
Thinnest in the Industry
First in Its Class
Use of a white LED and a one-package RGB light-receiving
element has made it possible to unify the Amplifier Unit,
both in size and operation, with conventional models.
If detection should become unstable, the Amplifier Unit can
be separately replaced to immediately regain stability.
Easy to Understand

Easy and Reliable ...Simplified Wiring Connector Reduces Work Steps
OMRON's unique simplified wiring connectors provide
the power for each added Sensor. Up to 16 Units can
be mounted, including a combination of Digital Fiber
Sensors and other simplified wiring connector
products such as Digital Laser Sensors.
This function guides the user to
ensure that the workpiece is in an
appropriate position for teaching.
(Indicates OVER, OK, or LOW.)
Power is supplied through the connector,
so only one output wire is
required. (For adding Sensors)

Wide Range of
Fiber Heads Available
Select from a wide range of Fiber Heads to match
the workpiece and working space.This makes
installation possible even in small spaces.

Many Compact Heads
Because it distinguishes RGB
ratios, detection is highly resistant
to workpiece movement.
Through-beam Fiber Heads are
capable of detecting color differences
in semi-transparent objects.
In Black Mode, black seam tape and
other black marks can be detected
regardless of film color or patterns.
If you teach the conveyor (i.e., the
background), you can detect
workpieces even if they have
different colors, shapes, or gloss.
Workpieces that absorb a specific
wavelength can be detected with
a wide range of wavelengths.
Four-color determination greatly
reduces the work required for line
switchovers.
*Switching banks requires 300 ms.

2.When teaching with/without a workpiece, the best sensing method will
be automatically selected (RGB ratio (C Mode) or light intensity deter-
mination (I Mode)). If color differences are not strong enough and RGB
ratios would result in unstable detection, then light intensity determina-
tion (I Mode) will be selected.
The detection mode can also be set to C, I, or Black Mode.
3.Input Specifications
Refer to the Instruction Manual for the external input pulse width.
A pulse width of 300 ms or longer is required to switch banks for the
E3X-DAC@B-S.
4.Mutual interference prevention cannot be used in super-high-speed
mode, and light intensity determination (I Mode) must be used.
5.With light intensity determination (I Mode), the correlation is not dis-
played, but rather the light intensity is displayed.
6.The allowable ambientoperating temperature changes according to the
number of Units that are linked.

Amplifier Unit
●Designing
Operation after Turning Power ON
The Sensor is ready to detect within 200 ms after the power
supply is turned ON. If the Sensor and load are connected to
separate power supplies, be sure to turn ON the Sensor first.
Time may be required for the degree of coincidence to stabi-
lize after the power supply is turned ON.
Operation When Turning Power OFF
Output pulses may occur when the power is turned OFF. Turn
OFF the power supply to the load and the load line before
turning OFF the power supply to the Sensor.
●Mounting
Connecting and Disconnecting Connectors
Mounting Connectors
1. Insert the Master or Slave Connector into the Amplifier Unit
until it clicks into place.
2. Attach the protector seals (provided as accessories) to the
sides of master and slave connectors that are not connect-
ed.
Note: Attach the seals to the sides with grooves.
Removing Connectors
1. Slide the slave Amplifier Unit(s) for which the Connector is
to be removed away from the rest of the group.
2. After the Amplifier Unit(s) has been separated,press down
on the lever on the Connector and remove it. (Do not at-
tempt to remove Connectors without separating them from
other Amplifier Units first.)
Adding and Removing Amplifier Units
Adding Amplifier Units
1. Mount the Amplifier Units one at a time onto the DIN track.
2. Slide the Amplifier Units together, line up the clips, and
press the Amplifier Units together until they click into place.
Removing Amplifier Units
Slide Amplifier Units away from each other, and remove from
the DIN track one at a time. (Do not attempt to remove Ampli-
fier Units from the DIN track without separating them first.)
Mounting the End Plate (PFP-M)
An End Plate should be used if there is a possibility of the Am-
plifier Unit moving, e.g., due to vibration.
Fiber Connection
The E3X Amplifier Unit has a lock button for easy connection
of the Fiber Unit. Connect or disconnect the fibers using the
following procedures:
1. Connection
Open the protective cover, insert the fibers according to the fi-
ber insertion marks on the side of the Amplifier Unit, and lower
the lock lever.
Precautions for Correct Use

Press down
Note:1.The specifications for ambient temperature will vary according to the
number of Amplifier Units used together. For details, refer to Ratings
and Specifications.
2.Always turn OFF the power supply before joining or separating Ampli-
fier Units.
Note: Do not pull on, compress, or otherwise exert excessive force on the fi-
bers after connecting them to the Amplifier Unit. (Do not exert more
than 0.3 N·m.)

2. Disconnecting Fibers
Remove the protective cover and raise the lock lever to pull
out the fibers.
●Adjusting
Mutual Interference Protection Function
Light from other sensors can cause the value on the digital
display to become somewhat unstable. If this occurs, reduce
the threshold to create a greater margin and enable more sta-
ble detection.
Output Short-circuit Protection
If the output short-circuit protection function operates because
the load connected to the control output is short-circuited,
OVER/CUR will flash on the display. Check the connection of
the load.
EEPROM Writing Error
If the data is not written to the EEPROM correctly due to a
power failure or static-electric noise, initialize the settings with
the keys on the Amplifier Unit. ERR/EEP will flash on the dis-
play when a writing error has occurred.
Optical Communications
Several Amplifier Units can be slid together and used in
groups. Do not, however, slide the Amplifier Units or attempt
to remove any of the Amplifier Units during operation.
●Others
Protective Cover
Always keep the protective cover in place when using the Am-
plifier Unit.
Fiber Unit
●Design Precautions
Applicable Fiber Units
Refer to the sensing distance tables on pages 8 to 11 for the
Fiber Units that can be used and the sensing distances. Ret-
ro-reflective, Limited-reflective, Ultra-compact, and Applica-
tion-specific Fiber Units, which are not listed, cannot be used.
●Installation Precautions
Glossy Sensing Objects
If the sensing object is glossy, detection may not be stable. If
the Sensor is inclined by 5°to 20°when using a glossy sens-
ing object, as shown below, detection capabilities can be in-
creased and stable detection achieved.
Note:1.To maintain the fiber properties, confirm that the lock is released be-
fore removing the fibers.
2.Be sure to lock or unlock the lock button within an ambient tempera-
ture range between −10°C and 40°C.

* Workpiece colors must always be taught to perform judgment for
registered workpiece colors.
* With the factory settings, 1-point teaching can be executed in RUN
mode.(Press the MODE Key for 3 s.)
Along with registering the workpiece colors, the threshold
can be set at approximately –10%of the match.
The setting is completed in a simple operation with one
press of a button.
Two points, with and without the workpiece, are detected,
and the match of the intermediate point is set as the
threshold value.
This method is ideal for setting thresholds with margins or
performing judgments with lowmatch.
