Precautions
To ensure safety, be sure to observe the following precautions.
◆
Wiring
●
Power Supply Voltage
• Do not use voltages above the allowable range. Applying a
voltage above the allowable range or applying an AC volt-
age (100 VAC) to a DC-type Sensor may result in burning
or damage.
●
Load Short-circuits
• Do not short-circuit the load. Doing so may result in burn-
ing or damage.
●
Incorrect Wiring
• Be sure to perform wiring correctly. Incorrect wiring may
result in burning or damage.
●
No-load Connection
• Connecting the power supply directly to the Sensor without
a load may result in burning or damage to internal ele-
ments. Be sure to connect a load when wiring.
◆
Installation
●
Influence of Surrounding Objects
• Performance may be adversely affected by conductive
objects (e.g., metals) in the vicinity of the Sensor. Ensure
that any conductive objects are separated from the Sensor
by at least the distances shown below.

●
Mutual Interference
• When installing 2 or more Sensors in series, in parallel, or
facing each other, be sure that they are separated by at
least the distances shown below.

The detection level for the top Sensor may change when the
detection level for the bottom Sensor is set. Be sure to set the
detection level for the bottom Sensor first.
