● 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

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.
