Ignores the background and detects the objects only. Smaller beam
makes it possible to detect small objects and narrow gaps between the
objects. The upgraded model is also less affected by the object colors.
Background Suppression
(BGS)
Coaxial Polarized Retro-reflective (Transparent Object Sensing)
Long Distance Detection
Several SA1E models are protected from incorrect wiring:
• Through-beam with infrared LED sensitivity adjustment
• Polarized retro-reflective with sensitivity adjustment
• Diffuse-reflective
• Background Suppression (BGS)
• Small-beam Reflective
The improved sensing ability detects objects of different
colors such as black and white more accurately.

Because the SA1E-X
co-axial polarized
retroreflective model does
not have blind zone,
where the reflected light
misses the light receiving
element, like the SA1E-P
polarized retro-reflective
type, the SA1E-X can be
used in applications
where objects pass near
the sensor.

•The stable LED turns on (green) either at stable incident or
stable interruption. Make sure to use the photoelectric switch
after the stable operation is ensured.
•In the light ON operation, the output turns on when the receiv-
ing light intensity level is 1.0 or over as shown on the right.
•In the dark-ON operation, the output turns on when the receiv-
ing light intensity level is 1.0 or less as shown on the right.

2. Optical Axis Alignment (Light ON)
Through-beam
Fasten the receiver temporarily. Place the projector to face the
receiver. Move the projector up, down, right and left to find the
range where the operation LED turns on. Fasten the projector in
the middle of the range. Next, move the receiver up, down, right
and left in the same manner and fasten in the middle of the range
where the operation LED turns on. Make sure that stable LED
turns on at stable incident and stable interruption.
Polarized retro-reflective
Install the reflector perpendicularly to the optical axis. Move the
SA1E photoelectric switch up, down, right and left to find the
range where the operation LED turns on. Fasten the switch in
the middle of the range. Polarized retro-reflective model can
be installed also by finding the position where the reflection of
projected red light is most intense, while observing the reflection
on the reflector from behind the switch. Make sure that stable
LED turns on at stable incident and stable interruption.
Diffuse-reflective/Small-beam reflective/
Convergent reflective
Place the SA1E photoelectric switch where the switch can detect
the object. Move the switch up, down, right and left to find the
range where the operation LED tuns on. Fasten the switch in
the middle of the range. Make sure that stable LED turns on at
stable incident and stable interruption. Because the light source
element of small-beam reflective model is a red LED, visual
inspection is possible as well.
3. Sensitivity Adjustment
Referring to the table at right, adjust the sensitivity of the
SA1E photoelectric switch when necessary, in such cases as
the through-beam model is used to detect small or translucent
objects or the reflective model is affected by background. The
table explains the status of operation LED when the operation
mode is set to light ON.
•After adjusting the sensitivity, make sure that stable LED turns
on at stable incident and stable interruption. For detecting ob-
jects too small to turn on the stable LED, use an optional slit.
•Sensitivity is set to the maximum (+) at the factory before ship-
ment. When adjusting the sensitivity, use the screwdriver sup-
plied with the SA1E photoelectric switch to turn the control as
shown below, to a torque of 0.05 N·m maximum.

4. Adjustment of Sensing Range for Background
Suppression (BGS) Model
•When adjusting the sensing range, follow the instruction below.
Step Distance Control Adjusting Procedure
1
Install the photoelectric switch and
the object firmly. Turn the control
counterclockwise until the operation LED
turns off (turns on with dark ON type). From
this point, turn the control clockwise until the
operation LED turns on (turns off with dark
ON type) (point A).
2
Remove the object, and confirm that the
operation LED turns off (turns on with dark
ON type). Turn the control clockwise until
the operation LED turns on (detecting the
background) (turns off with dark ON type)
(point B). (Note 1)
3Set the middle point between point A and B
as point C. (Note 2)
Note 1: When the background is far off and not detected, turn the
control 360°, and set the point as point C.
Note 2: Because the control is multi-turn, it may take more than
one turn to move from point A to point B.
Note 3: Turning the control clockwise lengthens the sensing dis-
tance.
Note 4: Background suppression (BGS) model is not provided with
a stable LED.

5. Power Supply and Wiring
•Do not use the SA1E photoelectric switch at the transient sta-
tus immediately after turning on the power (approx. 100 ms,
background suppression model: 200 ms). When the load and
switch use different power supplies, make sure to power up the
switch first.
•Use a power supply with little noise and inrush current, and use
the photoelectric switch within the rated voltage range. Make
sure that ripple factor is within the allowable limit. Do not apply
AC voltage, otherwise the switch may blow out or burn.
•When using a switching power supply, make sure to ground the
FG (frame ground) terminal, otherwise high-frequency noise
may affect the photoelectric switch.
•Turn power off before inserting/removing the connector on
photoelectric switch. Make sure that excessive mechanical
force is not applied to the connector. Connect the connector
cable to a tightening torque of 0.5 N·m maximum.
•To ensure the degree of protection, use the applicable con-
nector cable for the connector model. Connector cables are
ordered separately.
•Avoid parallel wiring with high-voltage or power lines in the
same conduit, otherwise noise may cause malfunction and
damage. When wiring is long, use a separate conduit for wiring.
•Use a cable of 0.3 mm2minimum core wires, then the cable can
be extended up to 100m.
6. Installation
Installing the Photoelectric Switch
•Do not install the SA1E photoelectric switches in an area where
the switches are subject to the following conditions, otherwise
malfunction and damage may be caused.
∗Inductive devices or heat source
∗Extreme vibration or shock
∗Large amount of dust
∗Toxic gases
∗Water, oil, chemicals
∗Outdoor
•Make sure to prevent sunlight, fluorescent light, and especially
the fluorescent light of inverters from entering the receiver of
the photoelectric switch directly. Keep the through-beam model
receiver away from intense extraneous light.
•Interference prevention allows two SA1E switches to be mount-
ed in close proximity. However, the through-beam model is not
equipped with interference prevention. Maintain appropriate
distance between the switches referring to the lateral displace-
ment characteristics.
•Because the SA1E photoelectric switches are IP67 waterproof,
the SA1E can be exposed to water. However, wipe water drops
and smears from the lens and slit using a soft cloth to make
sure of the best detecting performance.
•Polycarbonate or acrylic resins are used for optical elements.
Do not use ammonia or caustic soda for cleaning, otherwise
optical elements will be dissolved. To remove dust and moisture
build-up, use soft dry cloth.
•Tighten the mounting screws (M3) to a torque of 0.5 N·m. Do
not tighten the mounting screws excessively or hit the switch
with a hammer, otherwise the protection degree cannot be
maintained.
Installing the Reflector
•Use M4 mounting screws for the IAC-R5 and IAC-R8 reflector,
and M3 mounting screws for the IAC-R6 reflector. Tighten the
mounting screws to a tightening torque of 0.5 N·m maximum.
Mounting screws are not supplied with the switch.
•Use the M3 self-tapping screw, flat washer, and spring washer
to tighten the IAC-R7 reflector to a torque of 0.5 to 0.6 N·m.
•Optional reflector mounting bracket IAC-L2 is not supplied with
mounting screws or nuts.
•IAC-L3 and IAC-L5 are supplied with mounting screws for
mounting the reflector on the bracket.
•Reflector IAC-RS1 and IAC-RS2 can be installed directly on a
flat surface using the adhesive tape attached to the back of the
reflector. Before attaching the reflector, clean the board surface
to ensure secure attachment.
Installing the air blower mounting block SA9Z-A02
•When installing the SA9Z-A02 on the SA1E photoelectric
switch, use the attached M3 × 20 mounting screws and tighten
to a torque of 0.5 N·m maximum.
•Do not use the mounting screw (M3 × 12) supplied with the
mounting bracket (SA9Z-K01) to mount the SA1E photoelectric
switches.
•The SA9Z-A02 cannot be used with the through-beam slits
(SA9Z-S06 to S14).
•The air tube fitting (M5) can be installed to either the top or side.
The air tube is not supplied.
•Close the unused port using the air supply port plugging screw
and gasket (supplied with SA1E) to a tightening torque of 1 to
2 N·m maximum. The recommended air pressure is 0.1 to 0.3
MPa.
Installing the background suppression (BGS) model
•This sensor can detect objects correctly when the sensor head
is installed perpendicular to the moving object. Install the sen-
sor head as shown below to minimize sensing errors.

•If the sensor is used in a place subject to a large variations in
the ambient temperature, the characteristics may change de-
pending on the target object. Be sure to check the operation
under the actual operating conditions.
