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.

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

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.

Excessive light. Move the

head away from the work-

piece and find a position

where teaching is accepted.

The distance slightly away

from this position is the opti-

mum distance.

Move the head away by

approximately 20% of the

sensing distance.

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

set to B.

Mode

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

has three outputs in mode B and no ex

ternal

synchronous input will be accepted.

E3MC,

otherwise the E3MC may be damaged.

When

supplying power to the E3MC, make sure that the polarity

the

power is correct, otherwise the E3MC may be damaged.

ighten the Fiber Unit with a screwdriver to a torque of 0.2N

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.

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.

Mounting

When

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

for an instant but no control output will be turned ON.

When

using the Sensor for fine sensing, allow the system to

warm

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.

ypes of Power Supplies

No full-wave or half-wave rectified power supplies can be con-

nected

to the E3MC.

Power Supplies

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

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

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

EEPROM error may result if power supply

to the Sensor fails or

the

Sensor is influenced by static noise. The operation and bank

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

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.

the metal connector is not tightened securely

the metal connector

may be disconnected by vibration or the proper

degree of protection

the E3MC may not be maintained.

ater Precaution

void using the Sensor in water

, rain, or outdoors.

Protective Cover

Tighten

the operation cover to a torque of 0.2 to 0.3

m to ensure

proper

waterproofing.
