TECHNICAL GUIDE
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-X
can be adjusted to approximately 10° with the mounting holes.

On the other hand, sensing targets such as metal or transparent
plastic cases may be detected by allowing regular reflection.
E3MC-A
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
interference.

color objects can be
ignored while they are
passing the sensing
range.
Note: External Synchronous Input: Latches sensor output in existing state when ESI is on. For example, if sensor output is on when ESI
is on, the output(s) will remain on until ESI is turned off, regardless of target presence or absence.
For NPN models, ESI is turned on by connections to 0V.
For PNP models, ESI is turned on by connections to +V.

Terms
•
Conformity/Non-conformity
In the E3MC Color Sensor, term used to indicate when the
target color matches a reference color stored in the memory
bank(s). A match is “conformity,” and a mismatch is
“non-conformity.”
Lensed effect
Optical phenomenon where light passing through a
transparent object (bottle, for instance) is focused in the
same manner as a lens. If the lens effect is “converging,” the
light intensity may be increased significantly. When sensing
the presence of an object due to the attenuation of light
passing through that object, the lens effect may cause a
failure to detect the object. The light intensity may not be
reduced due to the “lens” effect of concentrating the light
beam.
•
D.O.
See Dark Operate.
L.O.
See Light Operate.
•
Light Operate
Operating mode where the output is turned on (transistor
conducts, or relay coil is energized) when light is received. In
the E3MC Color Sensor, refers to the mode where the output
turns on when the target color matches (conforms) to the
reference color stored in the memory bank.
•
Mutual Inference Protection
Circuitry that allows the sensor to detect and compensate for
interfering signals that may be emanating from sources within
its sensing range. Sensor can then operate normally, ignoring
the interfering signal(s).
•
nm
Nanometer; a measure of length, 10 --9 meters, 3.937 x 10 --8
inches.
•
NEMA
National Electrical Manufacturer’s Association; industrial
trade organization that publishes testing standards, including
enclosure ratings.
•
NPN
Transistor output designed to provide a path to ground for
current passing through the load (”sinking”). When the NPN
output is on, current can then pass from Positive, through the
load, and through the NPN transistor to ground, completing
the circuit.
•
PNP
Transistor output that provides a path to “Plus” for current
passing through the load (”sourcing”). When the PNP output
is on, current can then pass from Positive, through the PNP
transistor, through the load, and to ground, completing the
circuit.
•
Reflective Mode
See Diffuse Reflective.
•
Response time
Elapsed time from when a target moves into the sensing
zone of a sensor to when the output turns on. May also refer
to the “turn-off” time. The sum of turn-on and turn-off time is
the total cycle time (reciprocal of switching frequency, Hz).
•
Reverse Polarity Protection
Circuitry that prevents damage to the device if power is
incorrectly connected (polarity reversed, DC). The unit may
not work while polarity is reversed, but is undamaged, and
will work once polarity is corrected.
•
Color Registration
Detection of a special mark on packaging material referred to
as the Registration Mark. This mark is aligned with the
printed pattern on the wrapping material and allows proper
cut-off of the packaging material so that printed images
appear in the correct location on the package.
•
•
•
Dark Operate
Operating mode where the output is turned on (transistor
becomes conducting, or relay coil is energized) when light is
NOT received. In the E3MC Color Sensor, this refers to the
mode where the output turns on when the target color does
NOT match (non-conformity) the reference color stored in the
memory bank.
•
Diffuse Reflective
Sensor configuration with the emitter and receiver located in
the same housing. Sensing of target is based on reflection of
light from the target itself (rather than a retroreflector).
•
Excess Gain
See Stability Indicator.
•
External Synchronous Input
In the E3MC Color Sensor, an input that allows “latching” of
the output when the input is taken high, preventing a change
of state until the input is taken low.
•
IEC
International Electrotechnical Commission.
•
Interference Protection
See Mutual Interference Protection.
•
IP
International Protection; an international standard scale for
enclosure ratings (sealing).
•
IP66
Approximately NEMA 4, 4X, “heavy seas” test; the item is
subjected to a stream of water from a 1/2” nozzle with 14psi
pressure at a distance of 1.5 meter. Water must not enter the
item.
•
IP67
Approximately NEMA 6, “immersion” test; the item is
immersed under 1 meter of water for 30 minutes, with no
water entry.
•
kgf
Kilogram Force.
•
kgf cm
Kilogram-force centimeters, measure of torque;
1 kgf cm = 10.4 in lb.
E3MC
E3MC
•
RGB
Red, green, blue, refers to the triple light source in the E3MC
Color Sensor. By sensing the reflection level of each color,
the sensor can determine the exact color of the target.
•
Short Circuit Protection
Circuitry that prevents damage to a device’s output if the
output is short-circuited. Usually current is monitored, and the
output is turned off if current exceeds a predetermined value.
•
Stability Indicator
Indicator light that shows when a signal being received (such
as a light beam) is strong enough for stable operation.
Usually this stable operation is expressed as a percentage
above the switching threshold of the device.
•
Teach Function
Circuitry in a sensor that allows sensor threshold to be set
with the use of a “teach” input. Switching threshold is set
when the teach input is actuated, and it is based on signal
received at the moment of teaching.
•
Through-beam
Sensor where the emitter and receiver are in separate
housings, and arranged facing each other. The target would
be detected passing between the emitter and receiver,
interrupting the beam.

Precautions
AVOID DAMAGE TO THE E3MC
•
•
•
Voltage must not exceed the rated voltage of the E3MC.
When supplying power to the E3MC, make sure that the
polarity of the power is correct.
Do not short-circuit the load connected to the E3MC.
INSTALLATION
Power Up Ready
•
•
•
•
The E3MC is ready to sense objects 100 ms after the unit is
turned ON.
The 100 ms wait is also required when the E3MC output is
controlling other devices.
If power is supplied to the E3MC and the load independently,
be sure to turn ON the E3MC first.
When the E3MC is turned ON or OFF, the operation indicator
will be illuminated for an instant, but no control output will be
turned ON.
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, you should supply power to the timer or counter from
the same power supply as the E3MC.
Power Supplies
•
•
Power supply must be filtered with 10% MAX ripple (see
supply voltage specification).
When a switching regulator is required, you must connect the
FG (frame ground) and G (ground) terminals together, eliminating the switching noise of the regulator to avoid a malfunction.
WIRING
Cable
•
•
•
The cable can be extended up to 100 m, allowing for a cable
thickness of 0.3 mm2 maximum.
The cable must not be repeatedly bent.
Do not pull cables with pulling forces exceeding 50 N
(11.24 lb force).
M12 Metal Connector
•
•
•
When connecting or disconnecting the cable, first remove the
power to the E3MC.
To avoid damage, tighten the metal connector securely by
hand. Do not use any tools.
To ensure that the enclosure rating is maintained (so that
water/vibration ratings are assured), the cable connector
must be securely hand-tightened.
Avoid Damage or Malfunction Due to Induction Noise
•
Never run the E3MC Color Sensor cables in the same conduit with power lines or high tension cables.
FURTHER INFORMATION
Correcting an EEPROM Error
•
An EEPROM error may result if the power supplied to the
Sensor fails, or if the Sensor is influenced by static noise.
When an EEPROM error occurs, the operation and bank
indicators will flash and the buzzer will beep. The remedy is
to reprogram and make threshold level settings again.
