Color-Sensing
Engine

Easy and Reliable ... Featuring a Color-sensing Engine

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.

A high-power white LED and a multi-RGB processing system combine to cover all
RGB wavelengths, enabling easy and accurate detection of workpieces without
having to use a different light source to match each one.

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

Thinnest in the Industry

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 models.
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

10 mm

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)

Easy to Understand

A double display for easy, precise setting.

Reliable

One push is all it takes.

First in Its Class

This function guides the user to
ensure that the workpiece is in an
appropriate position for teaching.
(Indicates OVER, OK, or LOW.)

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.

Power is supplied through the connector,

so only one output wire is
required. (For adding Sensors)

Easy and Reliable Applications (Examples)

Detecting Marks

Because it distinguishes RGB
ratios, detection is highly resistant
to workpiece movement.

Distinguishing Trays * Detecting Wafers

Distinguishing
Semi-transparent Objects

Through-beam Fiber Heads are
capable of detecting color differences
in semi-transparent objects.

Detection distance:
30 mm

Detection distance:
9 mm

Detection distance:
3 mm

Detecting Black Marks

In Black Mode, black seam tape and
other black marks can be detected
regardless of film color or patterns.

Detecting Products on
Conveyors

Four-color determination greatly
reduces the work required for line
switchovers.

* Switching banks requires 300 ms.

Workpieces that absorb a specific
wavelength can be detected with
a wide range of wavelengths.

If you teach the conveyor (i.e., the
background), you can detect
workpieces even if they have
different colors, shapes, or gloss.

2.When teaching with/without a workpiece, the best sensing method will
be automatically selected (RGB ratio (C Mode) or light intensity deter­mination (I Mode)). If color differences are not strong enough and RGB
ratios would result in unstable detection, then light intensity determina­tion (I Mode) will be selected.
The detection mode can also be set to C, I, or Black Mode.
