Detection Level and Indicator
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)X@@ can be adjusted to
approximately 10° with the mounting holes.
On the other hand, sensing objects such as metal or transparent
plastic 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
discrimination mode to “Mode I” to achieve a more stable color
discrimination.
External Light
The E3MC may malfunction if it directly receives external light
interference. Provide a cover to shut-out such external light inter-
ference.
Adjustment of Sensing Distance of General-purpose Optical
Fiber Type
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.
Registered Color Selection
(Bank Selection Input)
1-output Models Only
The E3MC in RUN mode allows bank selection with external bank

and input 2 (green). The selected bank is indicated with the bank
selection indicator.

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
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
button and TEACH button together.
Checking Method
Mode A or B of the E3MC will be displayed for 3 s after mode set-
ting. 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.
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@ 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.
Remote Teaching Method
Function 1: Remote teaching with manual input through a
mechanical switch
Short-circuit the remote control input for 1.5 s or more to either of
the following terminals according to the E3MC model.

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.
Optical Fiber Type
Tightening Torque
The Fiber Unit must be tightened to a maximum torque of
0.54 N·m.
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.
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.
Do not apply excess force on the Fiber Unit.
The Fiber Head could be broken by excessive vibration. To pre-
vent this, the following is effective:
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.
Mounting
Tighten the Fiber Unit with a screwdriver to a torque of 0.2 N·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)Y@@, insert the fiber with
the line into the emitter section at the bottom of the amp.
Fiber Unit
Tightening Torque
When mounting the Fiber Unit, refer to the following table and
make sure that the tightening torque applied is correct.
Make sure that the size of the wrench applied to the nut is correct.
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 sin-
gle stroke. Do not stop the Cutting Tool midway.
Each insertion hole can be used only once. Do not use it again,
otherwise the fiber may not be cut properly and the sensing dis-
tance may decrease.

Connection
Do not pull the Fiber Unit with force exceeding 9.8 N or press the
Fiber Unit with force exceeding 29.4 N.
The fiber is so thin that the utmost attention will be required to
handle 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.
Do not press or place a load on the Fiber Unit.
The Fiber Head can be broken by excessive vibration. To prevent
this, the following is effective.
Built-in Amplifier Type
Tightening Torque
The Amplifier Unit must be tightened to a maximum torque of
2.3 N·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.
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 sup-
ply 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 con-
nected to the E3MC.
Power Supplies
Be sure to ground the FG (frame ground) and G (ground) termi-
nals 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 thick-
ness of the cord is 0.3 mm2 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 indicators will flash and the buzzer will beep if there is an
EEPROM error, in which case perform teaching and make thresh-
old 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 dis-
connecting the metal connector.
Tighten the metal connector securely by hand. Do not use any
tool, such as pliers, otherwise the metal connector may be dam-
aged.
If the metal connector is not tightened securely, the metal connec-
tor may be disconnected by vibration or the proper degree of pro-
tection 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·m to
ensure proper waterproofing.
