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.

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.

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.

Remote Teaching (Remote Control Function)
Mode Setting
Remote Teaching Method
When using the remote control function of the Sensor for remote
teaching, be sure to set the Sensor to mode B.
Function 1: Remote teaching with manual input through a
mechanical switch

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
Tighten the Fiber Unit with a screwdriver to a torque of 0.2N S m.
Fibers
Among the recommended fibers, the E32-CC200 and E32-D32L
have white or dotted yellow lines on the fiber to be inserted into the
emitter. When using the E3MC-(M)Yjj, insert the fiber with the
line into the emitter section at the bottom of the amp.
Optical Fiber Type
Fiber Unit
Tightening Torque
The Fiber Unit must be tightened to a maximum torque of
0.54 N S m.
Tightening Torque
When mounting the Fiber Unit, refer to the following table and make
sure that the tightening torque applied is correct.
Mounting
When Fiber Units are mounted to face each other, make sure to adjust the optical axes so that the Fiber Units will not be mutually interfered.
Screw-mounting Type
Mounting bracket

Handling the Fiber Unit
Do not pull or press the Fiber Unit.
Do not bend the Fiber Unit beyond 10 mm.
Do not bend the edge of the Fiber Unit.

Make sure that the size of the wrench applied to the nut is correct.
Incorrect
The Fiber Head could be broken by excessive vibration. To prevent
this, the following is effective:
Fiber Cutting
Insert the fiber into one of the insertion holes of the Cutting Tool to
cut the fiber to the desired length.
Press down the blade of the Cutting Tool to cut the fiber in a single
stroke. Do not stop the Cutting Tool midway.
A one-turn loop can
absorb vibrations.
Tape
General-purpose Optical Fiber Type
Insertion
The inserted Fiber Unit comes in contact with the internal rubber
packing first. Insert the Fiber Unit further until it comes in contact
with the innermost end.

View hole
Each insertion hole can be used only once. Do not use it again,
otherwise the fiber may not be cut properly and the sensing distance
may decrease.

Connection
Do not pull the Fiber Unit with force exceeding 9.8 N or press the

the fiber.
Do not bend the Fiber Unit beyond the permissible bending radius
provided in Ratings/Characteristics.
Do not bend the end of the Fiber Unit.

Installation
Power Reset Time
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.
Types of Power Supplies
No full-wave or half-wave rectified power supplies can be connected 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 mm2 maximum.
Repeated Bending
The cord must not be bent repeatedly.
Incorrect
The Fiber Head can be broken by excessive vibration. To prevent
this, the following is effective.
A one-turn loop can absorb vibrations.
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 conduit, 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
Tape
Built-in Amplifier Type
Tightening Torque
The Amplifier Unit must be tightened to a maximum torque of
2.3 N S m.
Mounting
When Sensors are mounted to face each other, make sure to adjust
the optical axes so that the Sensors will not be mutually interfered.
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 indicators will flash and the buzzer will beep if there is an EEPROM
error, in which case perform teaching and make threshold level settings again.
M12 Metal Connector
Make sure to connect or disconnect the metal connector after turning off the E3MC.
Make sure to hold the connector cover when connecting or disconnecting 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.
Water Precaution
Avoid using the Sensor in water, rain, or outdoors.
Protective Cover
Tighten the operation cover to a torque of 0.2 to 0.3 N S m to ensure
proper waterproofing.
