<Countermeasures for Switching Power Supplies>
(1) Attach a capacitor of 10 μF min. to the wires as close as possible
(2) Connect to the 0-V line of the power source or connect to the

• Take either of the following countermeasures as required if
connecting a Photomicrosensor with Modulated Light to a switching
power supply.
The line connected as mentioned above should be
grounded or connected to the mounting base to
ensure stable operation. (Recommended by power
supply manufacturers.)

objects.
Decrease reflection from the background object, e.g., by providing
a sufficient distance to the background or by using a black sponge
as the background.
