* Models numbers for Through-beam Sensors (E3S-AT@@) are for sets that include both the Emitter and Receiver.
The model number of the Emitter is expressed by adding "-L" to the set model number (example: E3S-AT11-L 2M), the model number of the Receiver, by adding "-D"
(example: E3S-AT11-D 2M). Refer to Ordering Information to confirm model numbers for Emitter and Receivers.

Adjustment Methods
Sensitivity Adjustment for Diffuse-reflective Sensors Set to Light ON
Unlike conventional Photoelectric Sensors, the variation in the sensitivity of E3S-A Photoelectric Sensors is minimal. This means
the sensitivity can be adjusted on only a single Photoelectric Sensor, and then the adjusters on the other Photoelectric Sensors
can be set to the same scale position. There is no need to adjust the sensitivity of each Photoelectric Sensor individually.

Item Sensing condition Sensitivity adjuster Indicators Procedure
1) Position A
Locate a sensing object at the sensing
distance, set the sensitivity adjuster to
the minimum scale position, and
gradually increase sensitivity by turning
the sensitivity adjuster clockwise until the
incident light indicator (red LED) is ON.
Position A is where the indicator has
turned ON.
2) Position B
Position B is when the sensing object is
removed and the sensitivity adjuster is
turned clockwise until the incident light
indicator (red LED) is ON. Position C is
where the adjuster is turned
counterclockwise (reducing the
sensitivity) from position B until the
incident light indicator (red LED) is OFF.
When there are no background objects,
the maximum sensitivity is position C.
3) Setting ---
Set the sensitivity adjuster to halfway
between (A) and (C) (at the optimum
sensitivity). Check that the stability
indicator (green LED) turns ON
according to whether the sensing object
is there or not. There is not sufficient
margin if it does not turn ON. If this is the
case, reconsider the detection method.

Safety Precautions
This product is not designed or rated for
ensuring safety of persons.
Do not use it for such purposes.
Do not use the product in atmospheres or environments that
exceed product ratings.
Mounting
Position of Optical Axis of Through-beam Model
Unlike conventional through-beam sensors, the E3S-A
Through-beam Photoelectric Sensor incorporates 2 lenses.
The lens actually in use is the one marked with an arrow
indicating the position of the optical axis. When using a Slit,
attach it to the lens marked with the arrow.
Tightening the Connector
Manually tighten the connector until the threads have
completely disappeared. If tightening is insufficient, the
degree of protection may not be maintained, or the connector
may become loose when it is subjected to vibration. Using
pliers to tighten the connector may damage it.
Use the E39-L60 Close Mounting Plate (provided) if the
Sensor is mounted using mounting brackets or if it is mounted
directly. (Refer to Dimensions.)
Mounting Bracket (Provided)
The direction of the optical axis coincides with the machine
axis of the E3S-A when the mounting screw is inserted into
the lock hole of the Mounting Bracket. If the mounting surface
and the screw hole are correctly aligned toward the sensing
object (or toward the Retroreflector for a Through-beam
Sensor), the mechanical axis and optical axis will be aligned
when the screw is inserted into the hole. Incident light will be
detected, and time-consuming adjustment will not be
necessary. (If, however, the mounting surface is not flat,
adjustment of the optical axis may still be required.)
Adjust the position of the Sensor so that incident light points
at the center. Make sure that the incident light is at a fixed
position.
The maximum tightening torque of the screw is 0.53 N.m max.
● Adjustments
E39-S46 Through-beam Slits
(Accessory, order separately)
Use the rubber attachment with the metal cover if a slit width
of 2 mm is required. (A Slit is not required in this case.) Insert
the 0.5- or 1-mm Slit between the metal cover and rubber
attachment if a slit width of 0.5 or 1 mm is desired.
These Slits fit into the rubber attachment.
Apply the Slit to the lens of the Photoelectric Sensor marked
with an arrow indicating the position of the optical axis (apply
it to the bottom lens of Horizontal Sensors and the top lens of
Vertical Sensors).

E39-E6 Polarized Mutual Interference Prevention Filters
for Through-beam Sensors
(Accessory, order separately)
•A set of 4 Filters are sold together for two Through-beam
Sensors (for 2 each for Emitters and Receivers). Order one
for every two sets of Photoelectric Sensors.
•For mounting, refer to the figure of the Through-beam Slits.
•The arrow printed on the cover indicates the direction of
polarization. By attaching the Filters opposite to each other
in polarization to the Emitters and the Receivers in rows,
mutual interference can be prevented (in any case, the
Filter attached to an Emitter and to the corresponding
Receiver must be the same in direction of polarization or the
Photoelectric Sensor will not function).
Operating Mode Selection
As shown in the following illustration, the E3S-A has an
operating mode selector on the panel where the Receiver
connector is located.
With this operating mode selector, the E3S-A is in either Dark-
ON or Light-ON mode.
and Switch
The Emitter of the Through-beam Sensor with the self-
diagnostic feature incorporates a turbo switch. When this
switch is ON, the intensity of the red LED light source can be
increased to make a brighter spot.
Function ( Switch)
The turbo function is effective with the turbo switch pressed,
and the function is reset automatically when released.
With the turbo function switched ON, the light spot is visible
even at a distance of 200 mm, making it easy to check the
sensing position and the angle of the optical axis.
Precautions
(1)Do not keep the turbo switch pressed for longer than 3
minutes. (It will not break even if it is pressed for an
extended period.)
(2)Pressing the switch may change the timer delay settings.
Set the timer after using the turbo function to check the
optical axis.
(3)To press the switch, use a force of 9.8 N max.
Using the E39-R5 Optical Axis Reflector for Through-
beam Sensors
(Accessory, order Separately)
Use this attachment when the set distance is long and
adjustment is mechanically difficult with a sensing object.
•Attach the Reflector to the Receiver.
•Look at the Reflector from right behind the Emitter. The
Reflector should be bright with red light when the optical
beam strikes the Reflector. If the Emitter has a turbo
function, the Reflector looks brighter with the function
switched ON.
•When the Reflector is removed, the light beam strikes the
Receiver.
Emitter
Receiver
Up to two units
can be attached.
Y = 0
Note: The arrows on the Filters can be attached in
either direction when two Sensors are
mounted next to each other. The Filter
attached to an Emitter and to the
corresponding Receiver must be the same
in direction of polarization or the Sensor will
not function.
