Never use this product as a sensing
device for personnel protection.
In case of using sensing devices for personnel
protection, use products which meet laws and standards,
such as OSHA, ANSI or IEC etc., for personnel protection
applicable in each region or country.
WARNING
Note: Each condition for use that the standards require is under
less than 2,000m above sea level.

Do not run the wires together with high-voltage lines or
power lines or put them in the same raceway. This can
cause malfunction due to induction.
In case noise generating equipment (switching
regulator, inverter motor, etc.) is used in the vicinity of
this product, connect the frame ground (F.G.) terminal
of the equipment to an actual ground.
Take care that the sensor is not directly exposed to fluorescent
light from a rapid-starter lamp, a high frequency lighting device
or sunlight etc. as it may affect the sensing performance.
If an external surge voltage exceeding 4kV (DC-voltage:
1kV) is impressed, the internal circuit will be damaged,
and a surge suppressing element should be used.
Do not use during the initial transient time (50ms) after
the power supply is switched on.
This sensor is suitable for indoor use only.
A mechanical structure is employed for the distance
adjuster of this product. Take care not to drop the product.
Do not use this sensor in places having excessive
vapor, dust, etc., or where it may come in direct
contact with water, or corrosive gas.
Take care that the sensor does not come in contact
with water, oil, grease, organic solvents, such as,
thinner, etc., strong acid or alkaline.
This sensor cannot be used in an environment
containing inflammable or explosive gases.
Never disassemble or modify the sensor.
Due to the configuration of the circuit, a slight noise
may be generated in this product, however, this is not
a problem.
WIRING CONNECTIONS

ە
ە
Check all wiring before applying power since incorrect
wiring may damage the internal circuit.
Also, carefully tighten the terminal screws so that the
wires of adjacent terminals do not touch.
The mounting hole for screw the terminal cover fixing
inclines 70 degrees to the
terminal cover, as shown
in the figure below.
To avoid damaging this
product or a screw, take
care when tightening or
loosening a screw.

This product has been developed / produced for
industrial use only.
Make sure that the power supply is off while wiring
and adjusting.
Take care that wrong wiring will damage the sensor.
Verify that the supply voltage variation is within the rating.
If power is supplied from a commercial switching
regulator, ensure that the frame ground (F.G.)
terminal of the power supply is connected to an
actual ground.

Care must be taken regarding the sensor mounting

If a specular body is present in the background, wrong
operation may be caused due to a small change in the
angle of the background body. In that case, install the
sensor at an inclination and confirm the operation with
the actual sensing object.
This product is not easily affected by the reflected light
intensity since this sensor is the adjustable range reflective
type. When the reflected light intensity is remarkably low, the
sensing range may be affected. In that case, mount the
sensor, while checking light-up of the stable indicator (green).
Mounting screws of the terminal cover and display
cover should certainly be tightened to maintain the
water tight rating, however, the tightening torque of the
screws should be of 0.3 to 0.5N

When detecting a specular object (aluminum or copper
foil, etc.) or an object having a glossy surface or
coating, please take care that there are cases when
the object may not be detected due to a small change
in angle, wrinkles on the object surface, etc.
When a specular body is present below the sensor, use the
sensor by tiling it slightly upwards to avoid wrong operation.
