4. Recommended installation
procedure
Install the sensor so that it is orientated
correctly in relation to the pass directions
of the target objects as shown in the
figure below.
1) Avoid using the sensor in
are made of polycarbonate resin and can
withstand water, alcohol, oils, salts and
weak acids. Other fluids such as
environments containing excessive
amounts of steam, dust, corrosive gas, or
where organic solvents are present.
2) When the sensor is used in noisy
environments, implement a
countermeasure such as connecting a
capacitor (Min. 33 µF) across the power
input terminals. Only use the sensor after
verifying actual operation.
alkalines, aromatic hydrocarbons and
halogenated hydrocarbons may melt or
swell the lens and case, please do not
have such fluids touch the lens and case.
5) If you use the sensor with a cover or
filter connected to the front of the sensor,
the sensor may detect the cover itself, the
detection distance can change, and
unstable operation can result.
6) If this sensor is used in a position
where it will be facing another sensor,
light will be received from the other
sensor which can cause mutual
interference and malfunction. Therefore,
please verify the installation conditions
before use.
7) When multiple sensors are to be used
side by side, please verify that there will
be no mutual interference by installing
them with the proper spacing, depending
on the type as shown below.

1) Check all wiring before applying
power. Incorrect wiring may damage the
internal circuit (in particular, check that
the connection to the power supply is not
reversed.)

For the general precautions, refer to
“NOTES FOR USING MOTION SENSOR
(Common)” on next page.
2) Avoid excessive removing and
replacing of the connector.
3. Detector surface (Optical surface)
1) Keep the detector surface clean.
Excessive dust or dirt on the detector
surface will deteriorate the sensing
performance.
2) Do not allow condensation or freezing
to occur on the surface of the sensor. If
condensation or freezing does occur at
low temperatures, the sensor may not
detect objects correctly.
3) This product is designed to detect the
existence of human bodies. The sensor
may not detect properly or the detection
distance may become unstable if the
objects consist of a low reflective material
(e.g., an object coated with black rubber,
etc.) or of a highly reflective material
(e.g., mirror, glass, coated paper, etc.).
