WIRING
A cable with a thickness of 0.3 mm
2
min. or AWG22 and a length
of 2 m max. must be connected to the output terminals.
To use a cable longer than 2 m, attach a capacitor with a
capacitance of approximately 10 F to the wires, as shown
below. The distance between the terminal and the capacitor must
be 2 m or less:
2 m max.
A capacitance of
10
F min.
5 to 24 VDC
Extension
cable
0 V
OUT
Avoid disconnecting from the photomicrosensor when power is
supplied to the photomicrosensor or the photomicrosensor could
be damaged.
If the metal mounting base is subjected to inductive electrical
noise, the photomicrosensor can be activated accidentally. If
noise is a problem, take the following precautions:
1. Connect the GND terminal to the mounting base, so there will
be no difference in electric potential between the photomicro-
sensor and mounting base.
2. Connect the GND terminal to the mounting base via a
0.47-
F capacitor.
3. Insert a plastic insulating plate with a thickness of approxi-
mately 10 mm between the photomicrosensor and mounting
base.
Wire, as shown by the following illustration, to connect a small
inductive load (a relay for example) to the photomicrosensor. A
diode must be connected parallel to the relay to absorb the
reverse voltage.

When using a standard switching regulator, ground the FG and G
terminal so that the photomicrosensor will be in a stable
operating condition.
