*1. Sensing distance values are for white paper.
*2. These sensing distance values apply when a E39-R12 Reflector is used. The MSR function is built-in. The reflected light from the object being measured may affect
the sensing accuracy, so adjust the threshold value before use.
*3. The beam radius is the value for the middle measurement distance and indicates a typical value for the middle sensing distance. The radius is defined by light
intensity of 1/e2 (13.5%) of the central light intensity.
Light will extend beyond the main beam and may be affected by conditions surrounding the object being measured.
*4. The E3C-LR12 has a fixed beam size (the focal point cannot be changed).

Safety Precautions
Refer to the Photoelectric Sensors Technical Guide.
WARNING
This product is not designed or rated for ensuring
safety of persons either directly or indirectly. Do not
use it for such purpose.
Never look into the laser beam.
Doing so continuously will result in visual
impairment.
Precautions for Safe Use
The following rules are required to ensure safety. Be sure to observe
these rules.
1. Installation environment
•Do not use in an environment where combustible or explosive gas
is present.
•To ensure safe operation and maintenance of the product, install
it away from high-voltage devices and power devices.
2. Power supply and wiring
•Do not exceed the rated voltage (12 to 24 VDC ±10%).
•Do not remove a connector while it is supplying power. This may
damage the product.
3. Other points
•Do not attempt to disassemble, repair, or modify the product.
•When disposing of the product, treat it as industrial waste.

E3C-LDA
Precautions for Correct Use
Do not use the product in atmospheres or environments that exceed
product ratings.
Official laser safety measures have been established regarding laser
devices both inside and outside of Japan. For details, refer to Laser
Beam Safety Standards.
●Mounting
Mounting and removing the sensor head
1. Open the protective cover.
2. With the locking lever on the sensor head connector facing up,
insert the connector into the connector opening.
Amplifier Units

●Designing
Operation after Turning Power ON
The Amplifier Unit is ready to operate within 200 ms after the power
supply is turned ON. If the Sensor and load are connected to power
supplies separately, be sure to turn ON the power supply to the
Sensor first.
Cleaning
Do not use thinner, benzene, acetone, or kerosene. If the filter on the
front of the sensor becomes soiled with dust, oil droplets, or other
materials,
(a) Use a blower brush (used to clean camera lenses) to blow large
dust particles from the surface. Do not blow the dust away with
your mouth.
(b) Use a soft cloth (for cleaning lenses) with a little alcohol to remove
the remaining dust.
Note: Do not use a scrubbing action when cleaning as a scratch on
the filter could result in the Sensor malfunctioning.
About the object
Measurement may not be possible or may not be precise with some
types of object materials and shapes (such as transparent objects,
objects with extremely low reflectance, objects smaller than the beam
diameter, objects with a large curvature, highly tilted objects, etc).

To remove the connector, press down on the locking lever and pull the
connector out.

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.)

Mounting and Removing Amplifier Units
Beam shape adjustment function
(Mounting Amplifier Units)
1. Mount the Amplifier Units one at a time onto the DIN track.
The shape of the beam at each sensing distance can be adjusted by
turning the beam shape control.

(E3C-LD11/-LR11)
Turn the control to the left to adjust the focal position to short distance
detection. Turn the control to the right to adjust the focal position to
long distance detection.

(E3C-LD21)
Turn the control to the left to decrease the beam width. Turn the
control to the right to increase the beam width.
(E3C-LD31)
Turn the control to the left to decrease the beam area. Turn the control
to the right to increase the beam area.
Do not turn the beam shape control to more than 60 mN⋅m.
Otherwise, this may damage the unit.
Do not turn the beam shape
control to more than 60 mN·m.
This may damage the unit.
(Separating 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 on page 5.
2. Always turn OFF the power supply before mounting 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. If a Mobile Console is going to be
mounted, connect the End Plate in the direction shown in the following
diagram.
Optical axis alignment function
The angle of beam projection can be adjusted by turning the optical
axis alignment control.
Turning the control about 45° to the right will move the optical axis to
the left by the number of degrees shown below.
Turning the control about 45° to the left will move the optical axis to
the right by the number of degrees shown below.
If the act of adjusting the optical axis changes the beam shape, adjust
the beam shape again. Turning the control 180° will return the optical
axis to its original position.
Adjustment angle
E3C-LR11 : Approx. 1.5°
E3C-LR12 : Approx. 1.0°
E3C-LD@@ : Approx. 2.0°
EEPROM Writing Error
End Plate
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.
Mounting the Mobile Console Head
Optical Communications
Leave a gap of at least 20 mm between the nearest Amplifier Unit and
the Mobile Console head.
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.
20 mm
●Other Precautions
Protective Cover
Always keep the protective cover in place when using the Amplifier
Unit.
Mobile Console
●Adjustments
Use the E3X-MC11-C1-SV2 Mobile Console for the E3C-LDA-series
Amplifier Units.
Mutual Interference Protection Function
There may be some instability in the digital display values due to light
from other sensors. If this occurs, decrease the sensitivity (i.e., decrease
the power or increase the threshold) to perform stable detection.
