Positioning made easy
Because the optical axis can be positioned
quickly, the photoelectric switch can be
installed on a machine or system easily, even in
applications requiring a long sensing range or
detection of small objects.
IDEC’s Unique Optical Lens Mechanism
Parallel beam to the housing axis makes
installation of the photoelectric switch easy.

Background Suppression (BGS)
fast response speed, and high precision sensing.
Detects fast-moving
objects
The 250 µs response speed is the fastest in its
class. Closely-spaced objects on a fast-moving
conveyor can be detected reliably.
IP67 structure can be used in environments
exposed to dust or water vapor.
Dust and water resistant
Because the visible red laser
is easy to see in both short (20
mm) and long (30 m) distances,
the detecting position and
optical axis can be found
quickly. The small beam can
detect small objects, and it also
enables easy positioning of the
sensor in applications where
the beam has to pass through
narrow spaces.
All models are Class 1 laser
compliant (JIS, IEC, FDA).

Fasten the receiver temporarily. Place the projector to face the
receiver. Move the projector up, down, right and left to nd 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 Retroreective
Install the reector perpendicularly to the optical axis. Move the
SA1E-L photoelectric switch up, down, right and left to nd the
range where the operation LED turns on. Fasten the switch in the
middle of the range. Make sure that stable LED turns on at stable
incident and stable interruption. When installing the reector
near the photoelectric switch, adjust the angle and positions of
photoelectric switch and reector so that sensing objects can be
detected reliably.
Background Suppression (BGS)
Place the SA1E-L photoelectric switch where the switch can
detect the object. Move the switch up, down, right and left to nd
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.
Sensitivity Adjustment
(Through-beam/Polarized Retroreflective)
•Referring to the table below, adjust the sensitivity of the SA1E-
L photoelectric switch when necessary, in such cases as the
through-beam is used to detect small or translucent objects. The
table explains the status of operation LED when the operation
mode is set to light ON.

SA1E-L Miniature Laser Photoelectric Switches (Built-in Amplifier)
Power Supply and Wiring
•Do not use the SA1E-L photoelectric switch in the transient
status immediately after turning on the power (approx. 100 ms).
When the load and switch use different power supplies, make
sure to power up the switch rst.
•Use a power supply with little noise and inrush current, and use
the photoelectric switch within the rated voltage range. Make
sure that the ripple 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 connec-
tor cable for the connector type. Connector cables are ordered
separately (see page 5).
•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 100 m.
Installation
Installing the Photoelectric Switch
•Do not install the SA1E-L 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
∗Outdoors
•Make sure to prevent sunlight, uorescent light, and especially
the uorescent light of inverters from entering the receiver of
the photoelectric switch directly. Keep the through-beam type
receiver away from intense extraneous light.
•Interference prevention allows two SA1E-L switches to be
mounted 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-L photoelectric switches are IP67 waterproof,
the SA1E-L 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.
•Acrylic resin is used for optical elements. Do not use ammonia or
caustic soda for cleaning, otherwise optical elements will be dis-
solved. To remove dust and moisture build-up, use soft dry cloth.
•Tighten the mounting screws (M3) to a torque of 0.4 to 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 reectors.
Tighten the mounting screws to a tightening torque of 0.4 to 0.5
N·m maximum. Do not tighten the mounting screws excessively,
otherwise the screw holes of the reector will be damaged.
•While optional reector mounting bracket IAC-L2 is not sup-
plied with mounting screws or nuts, the IAC-L3 and IAC-L5 are
supplied with mounting screws for mounting the reector on the
bracket.

SA1E-L Miniature Laser Photoelectric Switches (Built-in Amplifier)
Installing the air blower mounting block SA9Z-A02
•When installing the SA9Z-A02 on the SA1E-L photoelectric
switch, use the attached M3 mounting screws and tighten to a
torque of 0.4 to 0.5 N·m maximum.
•Mounting bracket is not supplied with SA9Z-A02 and must be
ordered separately. SA9Z-K01 mounting bracket can be used
with SA9Z-A02. When installing the SA9Z-K01 mounting bracket
on SA9Z-A02 air blower mounting block, use the M3 × 20 mount-
ing screws supplied with SA9Z-A02. Do not use the mounting
screws (M3 × 12) supplied with SA9Z-K01.
•The SA9Z-A02 cannot be used with the through-beam slits
(SA9Z-S12, SA9Z-S13, and SA9Z-S14).
•The air tube tting (M5) can be installed to either the top or side.
The air tube is not supplied.
•Close the unused port using the supplied air supply port plugging
screw (M5 × 6) and gasket 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) type
•This sensor can detect objects correctly when the sensor head is
installed perpendicular to the moving object. Install the sensor
head as shown below to minimize sensing errors.
•If the SA1E-L is used in a place subject to large variations in the
ambient temperature, the characteristics may change depending
on the target object. Be sure to check the operation under the
actual operating conditions.
•Polarized retroreective: when the sensing objects have mirror
surface, the reected light from the mirror surface might cause
false detection. Make sure that the reected light does not enter
the receiver.
