1. Senses Distances Twice as Far as those of
Conventional Model
The E3X-H senses distances twice as far as those
of the E3X-A. For example, the maximum sensing
distance of the through-beam M4 fiber model is 700
mm and that of the reflective model is 200 mm.
2. Incorporates Variable Hysteresis Function
Eight-turn Sensitivity Adjuster Ensures Fine
Sensitivity Adjustments
A maximum sensing distance of 350 mm is possible if
the long-distance M4 fiber model is used.
The E3X-A ensures a high-speed response of 200 µs,
which is ideal for a wide variety of applications.
Pulse Lighting Mechanism Enables a High-speed
Response of 20 µs
The E3X-F has excellent optical characteristics to with-
stand external disturbance. This model is ideal for the
high-speed positioning and detection of minute sensing
objects.
For example, the E3X-F detects with ease a 1-mm mark
on an object on a high-speed line that moves at the rate
of 30 m per second.
Green Light Source Accurately Senses Subtle
Differences in Color
Furthermore, the E3X-VG ensures a high-speed re-
sponse of 200 µs.

OMRON’s unique Fiber Units are available in a wide variety of models that includes
68 standard models and 362 modified models with or without special sleeves.
Common Characteristics
Ideal for Worldwide Use
The E3X models other than the E3X-H and E3X-VG have NPN or
PNP open collector output, thus ensuring worldwide use with ease.
All E3X models are available from OMRON’s 44 representatives in
25 countries.
A Series of E3X Models Incorporates a Variable
Timer Function
(Except the E3X-H11, which has a built-in 40-ms fixed timer)
A minute, high-speed signal is prolonged by the built-in OFF-delay
timer for a certain period, which makes it possible to input the signal
directly to Programmable Controllers in various lengths.
(The variable timer function is built into the self-diagnostic model.)

Note: 1. If the indicators operate as described in the table, the E3X can operate in stable condition within the rated temperature range.
2. Even when the green indicator is OFF, the E3X will operate stably if the operating temperature change since the initial setti ngs is
within ±10°C.
Light Axis Adjustment with Flashing Function
1. Set the mode selector to SET. 2. Adjust the light axis by moving the fiber with the light
flashing.
3. Set the mode selector to L-ON or D-ON after the light axis
is adjusted.
4. After adjusting the light axis, be sure to change the mode
to “L-ON” or “D-ON” before actually operating the Unit.

Alarm Output Function
With this function, the E3X checks changes in environmental condi-
tions (especially a change in the ambient temperature) and
self-diagnoses the resistance against the changes. The result is
shown by the indicators or an output signal.
Stability Indicator
(Green Indicator) Light Reception Indicator
(Red Indicator)
Displays
•Stability Indicator: Changes in environmental conditions
(changes in the ambient temperature, the operating voltage, or
the volume of dust) are checked and the resistance against them
are self-diagnosed. The result is shown via the indicator.
•Light Reception Indicator: The amount of light received is
indicated by this indicator.
Output
•The resistance against changes in environmental conditions is
indicated by the indicator and the result is output.
*If the alarm output is ON when the sensing object is moving at
low speed, use the E3X with an ON-delay timer circuit.

Variable Hysteresis Function (E3X-H11)
Sensing of Plate Level Differences
(If sensing is impossible with the hysteresis value set to maximum) Refer to the following when using the hysteresis adjuster .
Sensing operation is not stable because
zone B is within the hysteresis differential
range.
Reduce the sensitivity of the E3X with
the sensitivity adjuster and turn OFF
zone B.
Reduce the hysteresis value with the
hysteresis adjuster so that zone A will
be ON.

Locate the head
in zone B and turn the
hysteresis adjuster counterclockwise slowly
and make sure
that the light reception
indicator
is ON.
When the
head is located in zone B,
light reception indicator
is ON.
Set both the sensitivity adjuster
and hysteresis adjuster to maxi-
mum.
Decide the position of the fiber
head and that of the sensing
object in zone A.
Locate the head in zone A and
turn the sensitivity adjuster
counterclockwise slowly until the
stability indicator and light re-
ception indicator are OFF (i.e.,
position E as shown in the il-
lustration).
Sensing is possible.

Set the hysteresis adjuster to the
point where the light reception in-
dicator is ON (i.e., position H as
shown in the illustration).
The light reception indicator is
ON when the head is located in
zone B and the light reception
indicator is OFF when the head
is located in zone A.
Set the hysteresis adjuster to
maximum.
Locate the head in zone A and turn
the sensitivity adjuster clockwise
until the stability indicator and light
reception indicator are OFF (i.e.,
position F as shown in the illustra-
tion).
Locate the head in zone A and turn
the sensitivity adjuster counter-
clockwise until the light reception
indicator and stability indicator are
OFF. Confirm the position G that is
more sensitive than the position E.

External Check Input Function (E3X-A21/51, E3X-F21/F51, E3X-VG21)
With this function, light projection can be stopped when desired. The operation of the Sensor can be checked with this function before the E3X is
placed into actual operation.
E3X-Ajj
Light is emitted from the projection fiber head when the external
check input is ON. The Sensor, however, will not operate.
E3X-Fjj/-VGjj
No light is emitted from the projection fiber head when external
check input is ON.
By short-circuiting the pink and blue cords, light projection can
be stopped∗ (with a short-circuit current of 0.2 mA max.).

Precautions
General
Do not impose any voltage exceeding the rated voltage on the E3X.
Do not impose 100 V AC or more on models that operate with DC. In
both cases, the E3X may be damaged.
Do not short-circuit the load connected to the E3X, otherwise the
E3X may be damaged.
When supplying power to the E3X, make sure that the polarity of the
power is correct, otherwise the E3X may be damaged.
The load must be connected to the E3X in operation, otherwise the
E3X may be damaged.

Fiber Connection and Disconnection
The E3X Amplifier has a push lock. Connect or disconnect the fibers
to or from the E3X Amplifier using the following procedures:
1. Connection
Lock button
Fiber insertion mark
Fiber
Insert the fibers into the E3X Amplifier and press the push lock until
the Amplifier clicks to lock the fibers. The fibers will have insertion
marks when they are cut with the E39-F4 (Fiber Cutter). The portion
from the tips to the insertion mark should be inserted to the E3X.
2. Disconnection
Be sure to press the push lock again to unlock before pulling out the
fiber, otherwise the fiber may be deteriorated.
Fiber Insertion
If the portion from the tip to the insertion mark of the fibers are not
inserted into the Amplifier Unit, the sensing distance will be re-
duced.

Cutting Fiber
Insert a fiber into the Fiber Cutter and determine the length of the
fiber to be cut.
Press down the Fiber Cutter in a single stroke to cut the fiber.
An insertion mark can be placed on the fiber to serve as a reference
when inserting the fiber into the Amplifier . Use the following proce-
dure.
Insert the fiber all the way into the cutter and confirm that you can
see it in the hole at the back of the cutter , then press firmly down on
the cutter.
(2)
(1)
Insert the fiber into the Amplifier up to the insertion mark. Proper fi-
ber performance will not be achieved unless the fiber is inserted all
the way to the insertion mark. (This method is applicable to stan-
dard, 2.2-mm-diameter fibers only.)
12.6 Insertion mark
2.2-dia.
The cutting holes cannot be used twice. If the same hole is used
twice, the cutting face of the fiber will be rough and the sensing dis-
tance will be reduced. Always use an unused hole.
Use either one of the two holes on the right (refer to the following
figure) to cut a thin fiber as follows:
1. An attachment is temporarily fitted to a thin fiber before
shipment.
Temporarily fitted
2. Secure the attachment after adjusting the position of it in the

Minute Sensing Object
This datasheet shows typical examples for detecting minute ob-
jects. These typical examples are for reference use only, because
these example operations were tested on Units sampled at random
from a lot and the values described are average values. Do not
assume that all Units ensure such operations.
Others
When power is OFF:
The moment power is turned OFF , the E3X could output a pulse sig-
nal which could affect the operation of the devices connected to it.
This will happen more often if power is supplied to the E3X from an
external power supply, thus affecting the connected timer and
counter. Use a built-in power supply as much as possible to avoid
this.
If power is supplied to a photoelectric sensor through a cord that is
wired together with other power lines in the same duct, the cord will
be influenced by the power lines and malfunctioning of the photo-
electric sensor or damage could result. Wire the cord separately or
use a sealed cord to supply power to the photoelectric sensor.
In the case of the cord is extended, use a wire with 0.3 mm2 max.
The total length of the cord should be 100 m max.
Power line
Power supply:
If a standard switching regulator is used as a power supply, the
frame ground (FG) terminal and the ground (G) terminal must be
grounded, or otherwise the E3X can malfunction, influenced by the
switching noise of the power supply.
The supplied voltage must be within the rated voltage range. Unreg-
ulated full- or half-wave rectifiers must not be used as power sup-
plies.
Do not use a hammer to hit the Amplifier when mounting or the Am-
plifier will loose watertightness.

E39-F3A Reflective Unit Lens
When the E39-F3A is attached to the fiber, the E3X can sense the
light reflected from the interior of the E39-F3A. If this happens, ad-
just the sensitivity of the E3X Amplifier with Sensitivity Adjustor.
Place a sensing object or white paper at the sensing distance set
and adjust the insertion length of the Fiber Unit to the E39-F3A so
that the light spot is as small as possible. Then fix the position of the
Fiber Unit with the hexagonal wrench (attachment)

Liquid Level Sensing Position:
The liquid level sensing position is located 5.2±2 mm above the tip of
the PTFE part. Refer to the illustration below.
The precise liquid level sensing position varies with the surface ten-
sion of the liquid and the wet condition of the sensing position.

The Fiber Unit must be secured at sections that cannot be bent. Do
not secure the Fiber Unit at sections that can be bent, otherwise pre-
cise liquid level detection may not be possible.
The side or bottom of the tank may affect the Fiber Unit and lower
the performance of the Fiber Unit. In that case, locate the Fiber Unit
far enough from the side or bottom of the tank or coat the side or bot-
tom of the tank with black paint.
The operation of the Fiber Unit may not be stable in the following
cases:
1. The cone part of the Sensor Head has gathered air foam.
2. The cone part of the Sensor Head has gathered dissolved
substances.
3. The viscosity of the liquid is excessively high.
Some liquids, such as milky liquids, may not be detected.
Make sure that the tip of the Fiber Unit does not hit hard objects.
Operation may become unstable if the sensing head is scratched or
deformed.
When the Units are to be used in a dangerous environment, install
the Fiber Unit in a dangerous environment and the Amplifier Unit in a
safe environment.

Handling
Do not pull or press the Fiber Unit with any force exceeding 0.1 N S m
(1 kgf S cm).
Do not bend the Fiber Unit beyond the permissible bending radius.
If the pipe is secured with a mounting band, make sure that the pipe
will not be deformed.
The Fiber Unit may not operate properly if an opaque pipe is used.
The Fiber Unit may malfunction if the inner surface of the pipe gath-
ers water drops or condensation.
The casing material uses a polycarbonate resin, which is soluble in
alkaline, aromatic hydrocarbon, and chlorinated aromatic hydrocar-
bon solvents. Make sure that the casing is free from these materials.
If the background affects the Fiber Unit during operation, attach the
reflection preventing sheet provided with the Fiber Unit. This sheet
prevents the shifting of the Fiber Unit that may be caused by vibra-
tion.
