Easy and Reliable ... Featuring a Color-sensing Engine

The color-sensing engine uses three parameters, RGB, to process
incident light. It detects color information from the workpiece for precise
detection of color differences.

A high-power white LED and a multi-RGB processing system combine to cover all
RGB wavelengths, enabling easy and accurate detection of workpieces without
having to use a different light source to match each one.

Changes in the three parameters are processed as a ratio, so they are
not affected by light-intensity variations due to workpiece movement.

Thinnest in the Industry

A Slim, 10-mm-wide Amplifier Unit

Use of a white LED and a one-package RGB light-receiving
element has made it possible to unify the Amplifier Unit,
both in size and operation, with conventional models.
If detection should become unstable, the Amplifier Unit can
be separately replaced to immediately regain stability.

Easy and Reliable ... Ease of Use and Smart Functions

10 mm

In addition to ensuring easy use, we have added a number of smart
functions, such as remote control to simplify setup, and twin
sensing and output to simultaneously distinguish two registered
colors. (advanced models)

Easy to Understand

A double display for easy, precise setting.

Reliable

One push is all it takes.

Easy Setting

First in Its Class

This function guides the user to
ensure that the workpiece is in an
appropriate position for teaching.
(Indicates OVER, OK, or LOW.)

Easy and Reliable ... Simplified Wiring Connector Reduces Work Steps

OMRON's unique simplified wiring connectors provide
the power for each added Sensor. Up to 16 Units can
be mounted, including a combination of Digital Fiber
Sensors and other simplified wiring connector
products such as Digital Laser Sensors.

Power is supplied through the connector,

so only one output wire is
required. (For adding Sensors)

Easy and Reliable Applications (Examples)

Detecting Marks

Because it distinguishes RGB
ratios, detection is highly resistant
to workpiece movement.

Distinguishing Trays * Detecting Wafers

Distinguishing
Semi-transparent Objects

Through-beam Fiber Heads are
capable of detecting color differences
in semi-transparent objects.

Detection distance:
30 mm

Detection distance:
9 mm

Detection distance:
3 mm

Detecting Black Marks

In Black Mode, black seam tape and
other black marks can be detected
regardless of film color or patterns.

Detecting Products on
Conveyors

Four-color determination greatly
reduces the work required for line
switchovers.

* Switching banks requires 300 ms.

Workpieces that absorb a specific
wavelength can be detected with
a wide range of wavelengths.

If you teach the conveyor (i.e., the
background), you can detect
workpieces even if they have
different colors, shapes, or gloss.

2.When teaching with/without a workpiece, the best sensing method will
be automatically selected (RGB ratio (C Mode) or light intensity deter­mination (I Mode)). If color differences are not strong enough and RGB
ratios would result in unstable detection, then light intensity determina­tion (I Mode) will be selected.
The detection mode can also be set to C, I, or Black Mode.

7. Connect the load correctly.

8. Do not short-circuit the load at both ends.

9. Do not use the Sensor if the case is damaged.

10. Dispose of the Sensor as industrial waste.

11. Do not use the Sensor in locations subject to direct sun­light.

12. Burn injury may occur. The Sensor surface temperature
rises depending on application conditions, such as the
ambient temperature and the power supply voltage. Use
caution when operating or performing maintenance on the
Sensor.

14

Precautions for Correct Use

Do not use the product in atmospheres or environments that
exceed product ratings.

Amplifier Unit

● Designing

Operation after Turning Power ON

The Sensor is ready to detect within 200 ms after the power
supply is turned ON. If the Sensor and load are connected to
separate power supplies, be sure to turn ON the Sensor first.
Time may be required for the degree of coincidence to stabi­lize after the power supply is turned ON.

Operation When Turning Power OFF

Output pulses may occur when the power is turned OFF. Turn
OFF the power supply to the load and the load line before
turning OFF the power supply to the Sensor.

● Mounting

Connecting and Disconnecting Connectors

Mounting Connectors

1. Insert the Master or Slave Connector into the Amplifier Unit
until it clicks into place.

Insert

2. Attach the protector seals (provided as accessories) to the
sides of master and slave connectors that are not connect­ed.

E3X-DAC-S

Adding and Removing Amplifier Units

Adding Amplifier Units

1. Mount the Amplifier Units one at a time onto the DIN track.

2. Slide the Amplifier Units together, line up the clips, and
press the Amplifier Units together until they click into place.

Click into place

Removing Amplifier Units

Slide Amplifier Units away from each other, and remove from
the DIN track one at a time. (Do not attempt to remove Ampli­fier Units from the DIN track without separating them first.)

Note:1. The specifications for ambient temperature will vary according to the

number of Amplifier Units used together. For details, refer to Ratings
and Specifications.

2.Always turn OFF the power supply before joining or separating Ampli­fier Units.

Mounting the End Plate (PFP-M)

An End Plate should be used if there is a possibility of the Am­plifier Unit moving, e.g., due to vibration.

Seal

Note: Attach the seals to the sides with grooves.

Removing Connectors

1. Slide the slave Amplifier Unit(s) for which the Connector is
to be removed away from the rest of the group.

2. After the Amplifier Unit(s) has been separated, press down
on the lever on the Connector and remove it. (Do not at­tempt to remove Connectors without separating them from
other Amplifier Units first.)

Fiber Connection

The E3X Amplifier Unit has a lock button for easy connection
of the Fiber Unit. Connect or disconnect the fibers using the
following procedures:

1. Connection

Open the protective cover, insert the fibers according to the fi­ber insertion marks on the side of the Amplifier Unit, and lower
the lock lever.

● Adjusting

Mutual Interference Protection Function

Light from other sensors can cause the value on the digital
display to become somewhat unstable. If this occurs, reduce
the threshold to create a greater margin and enable more sta­ble detection.

Output Short-circuit Protection

If the output short-circuit protection function operates because
the load connected to the control output is short-circuited,
OVER/CUR will flash on the display. Check the connection of
the load.

Fiber Unit

● Design Precautions

Applicable Fiber Units

Refer to the sensing distance tables on pages 8 to 11 for th e
Fiber Units that can be used and the sensing distances. Ret­ro-reflective, Limited-reflective, Ultra-compact, and Applica­tion-specific Fiber Units, which are not listed, cannot be used.

● Installation Precautions

Glossy Sensing Objects

If the sensing object is glossy, detection may not be stable. If
the Sensor is inclined by 5° to 20° when using a glossy sens­ing object, as shown below, detection capabilities can be in­creased and stable detection achieved.

EEPROM Writing Error

If the data is not written to the EEPROM correctly due to a
power failure or static-electric noise, initialize the settings with
the keys on the Amplifier Unit. ERR/EEP will flash on the dis­play when a writing error has occurred.

Optical Communications

Several Amplifier Units can be slid together and used in
groups. Do not, however, slide the Amplifier Units or atte mpt
to remove any of the Amplifier Units during operation.
