Precautions
Refer to the Technical Information Section for general
precautions.

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
Do not solder the cable to the connectors. Use the EE-1002
Connector or EE-1003 Connector (with a 1-m cable attached) to
connect the cable to the output terminals.
Use the EE1003A Connector Holder to prevent accidental
disconnection of the EE-1003 Connector from the
EE-SPX301/401 Photomicrosensor.
Do not impose excessive force on the terminals (refer to the
diagram below). Excess force will damage the terminals.
Terminal
No
Do not disconnect the EE-1002 or EE-1003 Connector 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:
Connect the negative terminal to the mounting base, so there
will be no difference in electric potential between the photo-
microsensor and mounting base.
Connect the negative terminal to the mounting base through
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.

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