Safety Precautions
Refer to Warranty and Limitations of Liability.
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Make sure that this product is used within the rated ambient
environment conditions.
● Wiring
Soldering
• When direct soldering to the terminal, use the following guidelines.
Soldering Conditions
• The terminal base uses a polycarbonate resin, which could be
deformed by excessive soldering heat, resulting in damage to the
product’s functionality.
Cable Extension
• When extending the cable, use an extension cable with conductors
having a total cross-section area of 0.3 mm
2
. The total cable length
must be less than 10 m.
● Installation
The photomicrosensor is built into the device being used and so is not
equipped to deal with interference from an external light source.
When using the sensor in an area exposed to an incandescent lamp,
install so as to minimize the effects of external light sources.
● Sensitivity Adjustment
Use the special screwdriver (sold together) for sensitivity
adjustment.
• When an excessive force is applied to sensitivity adjuster, it may be
damaged.
• The shaft of the sensitivity adjuster is charged. Connect a DC
power supply incorporating an insulated transformer to the
photomicrosensor. Do not connect a DC power supply
incorporating an autotransformer or the user may receive an
electric shock when adjusting the sensitivity.

Adjustment
Procedure
1. Set the sensitivity of the
photomicrosensor to
minimum, place the sensing
object in the sensing
position, turn the sensitivity
adjuster clockwise slowly
until the light indicator is lit
(point A).
2. Remove the sensing object,
at which time the light
indicator will be OFF.
Further turn the sensitivity
adjuster clockwise slowly
until the light indicator is lit
again (point B). The
operation indicator will not
light again if the background
object does not reflect light,
in which case refer to
‘Sensitivity Adjustment with
No Background Object”.
3. Set the sensitivity adjuster
at the center (point C)
between point A and B.
Points A and B will be very
close if the sensor is
influenced by excessive
light reflected by the
background object, in which
case take the following
preventive measures.
(1) Separate the sensor and
the background object
by a distance of 20 mm
min.
(2) Cover the surface of the
background object with
a material with a small
reflection factor, such as
black sponge.
4.After setting the sensitivity
adjuster to point C, check if
the light indicator is lit on
placing the sensing object at
the sensing position and not
lit on removing the sensing
object.
