Precautions

Refer to the Technical Information Section for general

precautions.

JWIRING

A cable with a thickness of 0.3 mm2min. 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 µF to the wires, as shown

below. The distance between the terminal and the capacitor must

be 2 m or less:

2mmax.

A capacitance of

10 µFmin.

5to24VDC

Extension

cable

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-µF 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.

5to24VDC

OUT

JPOWER SUPPLY

When using a standard switching regulator, ground the FG and G

terminal so that the photomicrosensor will be in a stable

operating condition.
