RGB Color Sensor E3MC
RGB Color Sensor Discriminates
Delicate Differences in Color.
Best Color Sensor in the Industry.
Built-in LED light source ensures long service life
and maintenance-free operation.
Discriminates differences in color without being
influenced by changes in ambient temperature,
brightness of sensing objects, or positioning of
sensing objects.
Models with built-in amplifiers for long-distance
sensing and those with fiber heads for tiny spot
sensing are available.
Incorporates easy-to-see detection level and
threshold level indicators.
Degree
of protection to
IP66 and easy to maintain.
4-color registration/4-output models are also
available.

*Function Switch
The
following settings are possible in RUN or ADJ mode. In case of 4-output models, all channels are subject to the selection of the following
settings.
Each pin of the function switch is factory-set to the upper position.
Color Discrimination Mode Selection (Mode C is Recommended for Normal Applications)
Mode C: Color discrimination is performed according to R (red), G (green), and B (blue) ratio of the
reflection light even if the sensing objects fluctuate up and down within the rated sensing range.
Mode I:
Color discrimination is performed according to RGB light intensity of reflection light.
This mode ensures more delicate color discrimination than mode C.
Response Time Selection (Note: Figures in parentheses are for the 4-output models.)
3 ms (6 ms):
The E3MC can stably detect minute differences of color
. Set the
response time to 3 ms for usual applications.
1 ms (2 ms):
The E3MC will be in quick-response operation. Set the
response time to 1 ms if high-speed response is required.
OFF-delay Timer Setting
---: No OFF-delay timer is set.
TMR: A 40-ms OFF-delay timer is set for control output.
Conformity/Non-conformity Output
=: Output is ON when the detected color coincides with the registered color.
: Output is ON when the detected color does not coincide with the registered color.

Technical Guide
Detection
of Metal or Glossy Objects
If the E3MC does not detect metal or glossy objects accurately,
change the mounting angle of the E3MC so that it will not receive
regular
reflection light directly reflected from the objects.
The mounting angle of the E3MC-(M)Xjj can be adjusted to
approximately
10
°
with the mounting holes.

On the other hand, sensing objects such as metal or transparent

cases may be detected by allowing regular reflection.
Detection of White, Gray
, or Black Objects
When
registering white, gray
,
or black objects, change the color dis
-
crimination mode to “Mode I” to achieve
a more stable color discrim
-
ination.
External
Light
The
E3MC may malfunction if it directly receives external light inter
-
ference.
Provide a cover to shut-out such external light interference.
Adjustment
of Sensing Distance of General-purpose Optical
Fiber T
ype
Unlike the E3MC-A or E3MC-X, the E3MC-Y may require adjust-
ment
of its sensing distance depending on the reflection rate. This
also
applies to the thru-beam type.
Bring the fiber head as
close as possible to the workpiece
and conduct teaching.
Feed workpieces and
check if they are detected.

External Synchronous Input Function
The
measurement results will be directly output to the control output if the input from the external synchronous input terminal (pink) is set to OFF
.
The
output will hold the previous status if the input of the external synchronous input terminal is
set to ON. External synchronous input is valid in
RUN
or ADJ mode. As for the 4-output models, this function applies to the output of all the channels.

This status can be on hold by
an external synchronous input.
It will be released by setting the
external synchronous input to
OFF. This status can be on hold so
that unwanted color objects can
be ignored while they are
passing the sensing range.
Remote Teaching (Remote Control Function)
Mode Setting
When using the remote control function of the Sensor for remote
teaching,
be sure to set the Sensor to mode B.
Setting Method
Apply
power to the Sensor while pressing the SELECT DOWN
but
-
ton
and TEACH button together
.
Checking Method
Mode
A or B of the E3MC will be displayed for 3 s after mode setting.
When the mode selector is set to TEACH, the mode can be checked
from
the operation indicator
. The indicator will be lit when the mode
is
set to B.
Mode
A:
Operation indicator
is OFF.
Mode B:
Operation indicator
is ON.
Note: 1. The
Sensor is set to mode A before shipping.
2. The current mode selected does not change after the
Sensor
is turned OFF
.
3. The remote control function is available in RUN mode
and
ADJ mode only
.
4. The
E3MC-M
j
has three outputs in mode B and no ex
-
ternal
synchronous input will be accepted.
5. The
same switching procedure can be used for chang
-
ing
to mode A.

Precautions
General
Do not impose any voltage exceeding the rated voltage on the
E3MC,
otherwise the E3MC may be damaged.
When
supplying power to the E3MC, make sure that the polarity
of
the
power is correct, otherwise the E3MC may be damaged.
Do
not
short-circuit the load connected to the E3MC, otherwise the
E3MC
may be damaged.

Mounting
When
Sensors are mounted to face each

the
optical axes so that the Sensors will not be mutually interfered.
Installation
Power
Reset T
ime
The
E3MC is ready to sense objects from 100 ms after the E3MC is
turned ON, until when no devices connected the E3MC can be
used.
Be sure to
turn ON the E3MC first if power is supplied to the
E3MC
and the load independently
.
When
the E3MC is
turned ON or OFF
, the operation indicator will be
ON
for an instant but no control output will be turned ON.
When
using the Sensor for fine sensing, allow the system to
warm
up
for approximately 15 min after turning ON the power supply
.
Power OFF
The
E3MC may output a single pulse when the control power
supply
is turned OFF. If the E3MC is connected to a timer or counter to
which power is supplied from an independent power supply, the
E3MC
will be more likely to output a single pulse when the control
power
supply is turned OFF
. Therefore, supply
power to the timer or
counter
from the same power supply for the E3MC.
T
ypes of Power Supplies
No full-wave or half-wave rectified power supplies can be con-
nected
to the E3MC.
Power Supplies
Be
sure to ground the FG (frame ground) and G (ground) terminals if
a switching regulator is connected to the E3MC, otherwise the
E3MC
may malfunction due to the switching noise of the
switching
regulator.
Wiring
Cord
The
cord can be extended up to 100 m provided that the thickness of
the
cord is 0.3 mm
2
maximum.
Repeated Bending
The cord must not be bent repeatedly
.
High-tension Lines
The power supply lines of the Photoelectric Sensor must not be
wired
alongside power lines
or high-tension lines in the same con
-
duit,
otherwise the Photoelectric Sensor may become damaged
or
malfunction due to induction noise that may be generated from the
power
lines or high-tension lines. Route the lines separately or in a
single
conduit.
Cord Pulling Force
Do not pull cords with pulling forces exceeding 50 N.
Others
EEPROM Error
An
EEPROM error may result if power supply
to the Sensor fails or
the
Sensor is influenced by static noise. The operation and bank
in
-
dicators will flash and the buzzer will beep if there is an EEPROM
error,
in which case
perform teaching and make threshold level set
-
tings
again.
M12 Metal Connector
Make
sure to connect or disconnect the metal connector after turn
-
ing
of
f the E3MC.
Make
sure to hold the connector cover when connecting or discon
-
necting
the metal connector
.
Tighten
the metal connector securely by hand.
Do not use any tool,
such
as pliers, otherwise the metal connector may be damaged.
If
the metal connector is not tightened securely
,
the metal connector
may be disconnected by vibration or the proper
degree of protection
of
the E3MC may not be maintained.
W
ater Precaution
A
void using the Sensor in water
, rain, or outdoors.

the operation cover to a torque of 0.2 to 0.3
