Features
Models with New Connector System
Reduces Wiring, Saves Space, and Makes
Maintenance Easier
First in the Industry Patent Pending
In Amplifiers with wire-saving connectors, the power supply is
distributed to 1-conductor slave connectors through a 3conductor master connector. This design has three major
advantages.
1. Wiring time is significantly reduced.
2. Relay connectors are unnecessary, so wiring takes up less
space and costs are reduced.
3. Storage and maintenance are simpler because it isn't
necessary to distinguish between master connector and
slave connectors on the Amplifier.
Super Digital Display with Auto Power
Control (APC) Circuit
First in the Industry
The passage of time causes the intensity of the Sensor's lightemitting LED elements to deteriorate, which may make stable
detection impossible.
The E3X-DA-N is the first series of Fiber Sensors to use an
Auto Power Control (APC) circuit. This achieves strict
detection by eliminating fluctuation in the digital value and is
ideal for subtle detection such as stable detection of liquidcrystal glass.

E3X-DA-N
Power Consumption Reduced by As Much
As 70%
Digital Display Can Be Turned OFF or
Dimmed during Operation
Eco-mode
Power consumption is
reduced by as much as 70%
from 1800 mW to 600 mW
(when the digital display is
OFF).
When the digital display is viewed infrequently during
operation, current consumption can be reduced by dimming
the display or turning it OFF entirely.
(Eco-mode can be set from the Mobile Console only.)

New Generation of Mobile Consoles the Size of Cellular Phones.
Further Developing the Ultimate Power of Fiber Amplifiers.
Remote Setting and Adjustment
Perform settings, teaching, and fine adjustments at the
end of the Fiber Unit.
Previously, settings and
teaching could be performed
only on the Amplifier. Now,
however, using a Mobile
Console enables these
operations at the end of the fiber.
Strict adjustments can be made
while checking the workpiece
position.
With group teaching, teach multiple amplifiers
simultaneously.
The tedious teaching that had
to be performed separately for
each Amplifier can now be
performed for several
Amplifiers at once using the
Mobile Console.
Group teaching
Eliminate inconsistency by using group zero reset.
Display the light intensity and threshold at the same time.
New
Concept
The group zero reset function
can simultaneously reset the
digital displays of multiple
Amplifiers to 0. This function is
useful to minimize variation
between Amplifier values.
Patent Pending
Flash the Sensor head and display the amplifier channels
during operation.

● Area Sensing
Area sensing is possible using the threshold values
for channels 1 and 2.
• If channel 1 is set to L-ON, output turns ON when
the incident level is between the thresholds.
• If channel 1 is set to D-ON, output turns OFF
when the incident level is between the
thresholds.
The result is output to control output 1.
(Control output 2 is always OFF.)

Safety Precautions
WARNING
This product is not designed or rated for
ensuring safety of persons. Do not use it for
such purpose.
Precautions for Correct Use
Do not use the product in atmospheres or environments that
exceed product ratings.
Insertion position

Amplifiers
● 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.
● Mounting
Joining and Separating Amplifiers
Joining Amplifiers
(1) Mount the Amplifiers one at a time onto the DIN track.
(2) Slide the Amplifiers together, line up the clips, and press
the Amplifiers together until they click into place.
Clip
Fiber Connection and Disconnection
The E3X Amplifier uses a one-touch locking mechanism.
(Only the E3X-NM uses a locking button mechanism.)
Connect or disconnect the fibers to or from the E3X Amplifier
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, and lower the
lock button.
Click
into place
Fiber
Fiber insertion
mark
10.7 mm
(2) Disconnection
Remove the protective
cover and raise the
lock button to pull out
the fiber.
Protective cover
Locked
Unlocked
Note: To maintain the fiber properties, confirm that the
lock is released before removing the fiber.
(3) Precautions for Fiber Connection/Disconnection
Be sure to lock or unlock the lock button within an ambient
temperature range between −10 and 40°C.
Mounting the Mobile Console Head
Leave a gap of at least 20 mm
between the nearest Amplifier and
the Mobile Console head.
20 mm
Separating Amplifiers
Slide Amplifiers away from each other, and remove from the
DIN track one at a time. (Do not attempt to remove Amplifiers
from the DIN track without separating them first.)
Note 1. The specifications for ambient temperature will vary according to the
number of Amplifiers used together. For details, refer to Ratings and
Specifications.
2. Always turn OFF the power supply before joining or separating
Amplifiers.
Mounting the Mobile Console Head
With Twin-output models (E3X-DA@@TW), up to 16 channels
(i.e., eight E3X-DA@@TW Amplifiers) can be set using the
E3X-MC11 Mobile Console. (Operating modes and area
detection, however, cannot be set.)
● Adjustment
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., increase the threshold) to perform stable
detection.
EEPROM Writing Error
If the data is not written to the EEPROM correctly due to a
power failure during teaching or static-electric noise, repeat
the whole teaching procedure.

E3X-DA-N
Optical Communications
Several Amplifiers can be slid together and used in groups.
Do not, however, slide the Amplifiers or attempt to remove any
of the Amplifiers during operation.
Hysteresis Adjustment
The hysteresis setting can be adjusted using the Mobile
Console. Do not, however, set the hysteresis to a value lower
than the factory setting. Using a setting less than the factory
setting may result in incorrect operation.
The clip can also be removed using the following mechanism,
which is incorporated in the construction of the section
underneath the clip.
(1) Insert the clip to be removed into the slit underneath the
clip on another Amplifier.
Amplifiers with Connectors
● Mounting
Mounting Connectors
(1) Insert the Master or Slave Connector into the Amplifier
until it clicks into place.
(2) Remove the clip by rotating the Amplifier.
Rotate
Insert
(2) Join Amplifiers together as required after all the Master
and Slave Connectors have been inserted.
(3) Attach the stickers (provided as accessories) to the sides
of Master and Slave Connectors that are not connected to
other Connectors.

Removing Connectors
(1) Slide the slave Amplifier(s) for which the Connector is to
be removed away from the rest of the group.
(2) After the Amplifier(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
Amplifiers first.)

General Precautions
For precautions on individual products, refer to Safety Precautions in individual product information.
WARNING
These Sensors cannot be used in safety devices for
presses or other safety devices used to protect
human life. These Sensors are designed for use in
applications for sensing workpieces and workers
that do not affect safety.
Precautions for Safe Use
To ensure safety, always observe the following precautions.
● Wiring

Typical examples
Power Supply Voltage
Do not use a voltage in
excess of the operating
voltage range.
Applying a voltage in excess
of the operating voltage
range, or applying AC power
(100 VAC or greater) to a DC
Sensor may cause explosion
or burning.

Photoelectric Sensors Technical Guide
Precautions for Correct Use
● Design
Power Reset Time
Turning OFF Power
The Sensor will be ready to detect within approximately 100 ms after
the power is turned ON.
If the Sensor and the load are connected to separate power supplies,
turn ON the Sensor power before turning ON the load power. Any
exceptions to this rule are indicated in Safety Precautions in individual
product information.
An output pulse may be generated when the power is turned OFF. It
is recommended that the load or load line power be turned OFF
before the Sensor power is turned OFF.
Power Supply Types
An unsmoothed full-wave or half-wave rectifying power supply cannot
be used.
Mutual Interference
Mutual interference is a state where an output is unstable because the Sensors are affected by light from the adjacent Sensors.
The following measures can be taken to avoid mutual interference.
Countermeasure
1
2
Concept
Through-beam Sensors
Reflective Sensors
Use a Sensor
with the
interference
prevention
function.
If Sensors are mounted in close proximity, use Sensors with the interference prevention function.
10 or fewer Sensors: E3X-DA@-S, E3X-MDA, E3C-LDA Fiber Sensors
Performance, however, will depend on conditions. Refer to pages E3X-DA-S/E3X-MDA
and E3C-LDA.
5 or fewer Sensors: E3X-NA Fiber Sensors
2 or fewer Sensors: E3T, E3Z, E3ZM, E3ZM-C, E3S-C, E3G-L1/L3, or E3S-C Built-in Amplifier Photoelectric
Sensors (except Through-beam Sensors)
E3C Photoelectric Sensor with separate amplifier
Install an
inference
prevention
filter.
A mutual interference prevention polarizing filter can be
installed on only the E3Z-TA to allow close-proximity
mounting of up to 2 Sensors.
Mutual Interference Prevention Polarizing Filter: E39-E11
Separate
Sensors to
distance where
interference
does not occur.
Check the parallel movement distance range in the
catalog, verify the set distance between adjacent
Sensors, and install the Sensors accordingly at a
distance at least 1.5 times the parallel movement
distance range.
--If the workpieces move from far to near, chattering may
occur in the vicinity of the operating point. For this type of
application, separate the Sensors by at least 1.5 times the
operating range.

Sensor
Close mounting of Sensors is possible by alternating
the Emitters with the Receivers in a zigzag fashion (up
to two Sensors). However, if the workpieces are close
to the Photoelectric Sensors, light from the adjacent
Emitter may be received and cause the Sensor to
change to the incident light state.

Adjust the
sensitivity.
If there is a possibility that light from another Sensor
may enter the Receiver, change the position of the
Emitter and Receiver, place a light barrier between the
Sensors, or take other measures to prevent the light
from entering the Receiver.
(Light may enter even if the Sensors are separated by
more than the sensing distance.)
If Sensors are mounted in opposite each other, slant the
Sensors as shown in the following diagram. (This is
because the Sensors may affect each other and cause
output chattering even if separated by more than the
Sensor sensing distance.)

● Wiring
Cable
Separation from High Voltage (Wiring Method)
Unless otherwise indicated, the maximum length of cable extension is
100 m using wire that is 0.3 mm2 or greater.
Exceptions are indicated in Safety Precautions in individual product
information.
Do not lay the cables for the Sensor together with high-voltage lines
or power lines. Placing them in the same conduit or duct may cause
damage or malfunction due to induction interference. As a general
rule, wire the Sensor in a separate system, use an independent metal
conduit, or use shielded cable.
Cable Tensile Strength
When wiring the cable, do not subject the cable to a tension greater than
that indicated in the following table.
Cable diameter
Less than 4 mm
4 mm or greater
Tensile strength
30 N max.
50 N max.
Note: Do not subject a shielded cable or coaxial cable to tension.
Repeated Bending
Power line
Work Required for Unconnected Leads
Unused leads for self-diagnosis outputs or other special functions
should be cut and wrapped with insulating tape to prevent contact with
other terminals.
Normally, the Sensor cable should not be bent repeatedly.
(For bending-resistant cable, see Attachment to Moving Parts on
page C-4.)

● Mounting
Attachment to Moving Parts
To mount the Photoelectric Sensor to a moving part, such as a robot
hand, consider using a Sensors that uses a bending-resistant cable
(robot cable).
Although the bending repetition tolerance of a standard cable is
approximately 13,000 times, robot cable has an excellent bending
tolerance of approximately 500,000 times.
Cable Bending Destruction Test (Tough Wire Breaking
Test)
With current flowing, bending is repeated to check the number of
bends until the current stops.

● Adjustments
Optical Axis Adjustment
Securing Fibers
The E3X Fiber Unit uses a one-touch locking mechanism. Use the
following methods to attach and remove Fiber Units.
(1) Attaching Fibers
Open the protective cover, insert the fiber up to the insertion mark on
the side of the Fiber Unit, and then lower the lock lever.
Move the Photoelectric Sensor both vertically and horizontally and set
it in the center of the range in which the operation indicator is lit or not
lit. For the E3S-C, the optical axis and the mechanical axis are the
same, so the optical axis can be easily adjusted by aligning the
mechanical axis.

● Operating Environment
Water Resistance
● Maintenance and Inspection
Points to Check When the Sensor Does Not Operate
Do not use in water, in rain, or outside.
• If the Sensor does not operate, check the following points.
(1) Are the wiring and connections correct?
(2) Are any of the mounting screws loose?
(3) Are the optical axis and sensitivity adjusted correctly?
(4) Do the sensing object and the workpiece speed satisfy the ratings
and specifications?
(5) Are any foreign objects, such as debris or dust, adhering to the
Emitter lens or Receiver lens?
(6) Is strong light, such as sunlight (e.g., reflected from a wall), shining
on the Receiver?
(7) Do not attempt to disassemble or repair the Sensor under any
circumstances.
(8) If you determine that the Sensor clearly has a failure, immediately
turn OFF the power supply.
Ambient Conditions
Do not use this Sensor in the following locations. Otherwise, it may
malfunction or fail.
(1) Locations exposed to excessive dust and dirt
(2) Locations exposed to direct sunlight
(3) Locations with corrosive gas vapors
(4) Locations where organic solvents may splash onto the Sensor
(5) Locations subject to vibration or shock
(6) Locations where there is a possibility of direct contact with water,
oil, or chemicals
(7) Locations with high humidity and where condensation may result
Environmentally Resistive Sensors
The E32-T11F/T12F/T14F/T81F-S/D12F/D82F and E3HQ can be used
in locations (3) and (6) above.
Optical Fiber Photoelectric Sensors in Explosive Gas
Atmospheres
The Fiber Unit can be installed in the hazardous area, and the
Amplifier Unit can be installed in a non-hazardous area.
<Reason>
For explosion or fire due to electrical equipment to occur, both the
hazardous atmosphere and a source of ignition must be in the same
location. Optical energy does not act as an ignition source, thus there
is no danger of explosion or fire. The lens, case, and fiber covering are
made of plastic, so this setup cannot be used if there is a possibility of
contact with solvents that will corrode or degrade (e.g., cloud) the
plastic.
<Ignition Source>
Electrical sparks or high-temperature parts that have sufficient energy
to cause explosion in a hazardous atmosphere are called ignition
sources.
Hazardous area
Non-hazardous area
Fiber Unit
Amplifier Unit
Sensing object
Lens and Case
The lens and case of the Photoelectric Sensor are primarily made of
plastic. Dirt should be gently wiped off with a dry cloth. Do not use
thinner or other organic solvents.
• The case of the E3ZM, E3ZM-C and E3S-C is metal. The lens,
however, is plastic.
● Accessories
Using a Reflector (E39-R3/R37/RS1/RS2/RS3)
During Application
(1) When using adhesive tape on the rear face, apply it after washing
away oil and dust with detergent. The Reflector cannot be
mounted if there is any oil or dirt remaining.
(2) Do not press on the E39-RS1/RS2/RS3 with metal or a
fingernail.This may weaken performance.
(3) This Sensor cannot be used in locations where oil or chemicals
may splash on the Sensor.
M8 and M12 Connectors
• Be sure to connect or disconnect the connector after turning OFF
the Sensor.
• Hold the connector cover to connect or disconnect the connector.
• Secure the connector cover by hand. Do not use pliers, otherwise
the connector may be damaged.
• If the connector is not connected securely, the connector may be
disconnected by vibration or the proper degree of protection of the
Sensor may not be maintained.
● Others
Influence from External Electrical Fields
Values Given in Typical Examples
Do not bring a transceiver near the Photoelectric Sensor or its wiring,
because this may cause incorrect operation.
The data and values given as typical examples are not ratings and
performance and do not indicate specified performance. They are
rather values from samples taken from production lots, and are
provided for reference as guidelines. Typical examples include the
minimum sensing object, engineering data, step (height) detection
data, and selection list for specifications.
Cleaning
• Keep organic solvents away from the Sensor. Organic solvents will
dissolve the surface.
• Use a soft, dry cloth to clean the Sensor.
