WARNING
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Precautions for Correct Use
Make sure that this product is used within the rated ambient
environment conditions.
● Wiring
Soldering
● 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.
• When direct soldering to the terminal, use the following guidelines.

The portion between the base of
the terminals and the position
1.5 mm from the terminal base
must not be soldered.
• The terminal base uses a polycarbonate resin, which could be
deformed by excessive soldering heat, resulting in damage to the
product’s functionality.
Insulated transformer
Cable Extension
• When extending the cable, use an extension cable with conductors
having a total cross-section area of 0.3 mm2. 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.
