Changes in the three parameters are processed as a ratio, so they are not affected by light-intensity
variations due to workpiece movement.

Amplifier Unit
A Slim, 10-mm-wide Amplifier Unit
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 fiber-optic sensors.
If detection should become unstable, the
Amplifier Unit can be separately replaced to
immediately regain stability.

Easy and Reliable ... Ease of Use and Smart Functions
In addition to ensuring ease of use, a number of smart functions have been included such as a
remote control to simplify setup. Advanced models offer twin sensing and output to simultaneously
distinguish two registered colors.
First in Its Class
The Setting guide function
shortens set-up and
improves reliability. It
guides the user to place
the workpiece in an
appropriate position
for teaching. (Indicates
OVER, OK, or LOW.)
Easy to understand
A double display for easy, precise setting.
Easy Setting
One push is all it takes.
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 Digital Laser Sensors
that feature simplified wiring connectors.
Conventional fiber-optic
amplifiers require three
wiring connections for
each sensor.
Shown: 15 wires plus extension connector wires.
The new E3X-DAC-S
requires three wires for
the master sensor only.
Each additional sensor in
a group requires only one
wiring connection.
Shown: Only 7 wires with no additional
extension connectors.

Easy and Reliable Applications (Examples)
Detecting Marks
Distinguishing Products
Because it distinguishes RGB
ratios, detection is highly resistant
to workpiece movement.
Detection is highly resistant to the
effects of backgrounds and
surface protrusions.

Semi-transparent Objects
Distinguishing Trays
Workpieces that absorb a specific
wavelength can be detected with
a wide range of wavelengths.

Through-beam Fiber Heads are
capable of detecting color differences
in semi-transparent objects.
Twin sensing and remote control
functions simplify setup of color
sortation on a multi-product line.
