Easy-Teach Colour Detection Sensor
E3X-DACLR
Easy-Teach Colour Detection Sensor
The E3X-DACLR provides reliable and easy to set up one-touch
colour verification. Up to four colours can be identified. The separate
amplifier allows mounting in easily accessible areas for operators
while the small sensor head can be mounted in locations even when
space is limited.
• Easy to set up one-touch colour verification for 1 to 4 colours
• Model for remote teaching
• Small sensor head for easy mounting even when space is tight
• White LED and multi detection modes for reliable operation even for
challenging applications

Ratings and Specifications
Amplifier Units
*1. 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 be set to C, I, or Black Mode.

Nomenclature
Safety Precautions
Refer to Warranty and Limitations of Liability.
This product is not designed or rated for
ensuring safety of persons either directly or
indirectly.
Do not use it for such purposes.
Do not use the product with voltage in excess
of the rated voltage. Excess voltage may result
in malfunction or fire.
Never use the product with an AC power
supply.
Otherwise, explosion may result.
High-temperature environments may result in
burn injury.
The following precautions must be observed to ensure safe
operation of the Sensor.
1. Do not use the Sensor in an environment where explosive
or flammable gas is present.
2. Do not use the Sensor in a location subject to splattering
of water, oils, or chemicals.
3. Do not attempt to disassemble, repair, or modify the
Sensor.
4. Do not apply voltages or currents that exceed the rated
range to the Sensor.
5. Do not use the Sensor in an ambient atmosphere or
environment that exceeds the ratings.
6. Wire the power supply correctly, including the polarity.
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.

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

Note 1. The specifications for ambient temperature will vary according to the
number of Amplifier Unit used together. For details, refer to Ratings
and Specifications
2. Always turn OFF the power supply before joining or separating
Amplifier Units.

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 and raise the lock lever to release
the lock. Next, insert the fibers according to the fiber insertion
marks on the side of the Amplifier Unit, and lower the lock
lever.
Note: If one of the fibers from the Fiber Unit has a white line, such as with a Coaxial
Sensor, that fiber is for the Emitter. Insert it into the Emitter section. Refer to
Dimensions for the Fiber Unit to see if there is an Emitter fiber.
2. Disconnecting Fibers
Remove the protective cover and raise the lock lever to pull
out the fibers.
●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-circuits Protection
OVER/CUR will flash on the display if the output short-circuit
protection function operates due to a load short-circuit in a
control output. If this occurs, check the load connections.
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 attempt
to remove any of the Amplifier Units during operation.
●Others
Protective Cover
Always keep the protective cover in place when using the
Amplifier Unit.
Fiber Unit
●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.
Note: Do not pull on, compress, or otherwise exert excessive force on the fibers
after connecting them to the Amplifier Unit. (Do not exert more than 0.3
N·m.)
Note 1. To maintain the fiber properties, confirm that the lock is released before
removing the fibers.
2. Be sure to lock or unlock the lock button within an ambient temperature
range between 10C and 40C.
