E3MC
RGB Color Sensor Discriminates Delicate
Differences in Color.
Features
Stable and Powerful Detection for Inline Use
Long-distance Sensing with Built-in Amplifier Type
Built-in amplifier type with a sensing distance of 60±10 mm is
available for a wide range of color discriminating applications.
Highly Resistant to Changes in Sensing Object Brightness and Ambient Temperature.
• OMRON's unique Free Angle Optics (FAO: multi-layer polarized filter) is highly resistant to changes in the tint or
brightness of sensing objects. Capable of discriminating
over 90 different colors.
• Wide temperature range from -20°C to 55°C and excellent
detection stability.
Maintenance-free LED Light Source
Incorporates RGB LED light sources with a long service life
more than several tens of thousand hours.
Great maintenance-cost saver ensuring high performance
(Halogen lamps used as light sources must be replaced or readjusted every nine months or so.)
Double Indication ensuring high
visibilty.
• Conformity with the registered colors can
be monitored at eight levels. (Detection
level indicators)
• Allows fine adjustment between fine or
rough discrimination while monitoring the
measured results. (Threshold level indicators)

Principle of Detection
The E3MC detects colors by making use of the fact that the reflection ratio of a primary color (i.e. red, green or blue) reflected by an
object varies with the chromatically of the object. By using a hightech, multi-layer polarized filter called FAO (free angle optics), the
E3MC emits red, green and blue light on a single optical axis. The
E3MC receives the light reflected by the sensing objects through
the receiver and processes the red-green-blue ratio of the light to
discriminate the color of the sensing object.

Application
Features
Excellent Protective Structure and Maintenance Performance
The amplifier unit uses a sturdy metal body. The unit including
the fiber head satisfies the water resistance of IEC Standard
IP66. You can use the E3MC without any problems in a wide
range of applications. In addition to this, the M12 metal connector has improved maintenance performance.
Discriminating Delicate Color Differences
The detection level indicators are lit according to the degree
of conformity between registered and detected colors. Delicate color differences are discriminated by setting the threshold to a superior level. (Fine discrimination is expected.)
Sensor errors that may be caused by minor tint differences or
dirt retention are prevented by setting the threshold to a lower
level. (Rough discrimination is expected)
Conversion of Color Data into RGB Analog
Data
The analog output type can control the color change history
and distribution in analog form. Different type discrimination
can also be performed without bank restrictions by CPU processing.
