● Wiring
Power Supply
• If the load and Sensor are connected to different power supplies,
always turn ON the Sensor power first.
• Switching noise can cause operating mistakes if a commercial
switching regulator is used. When using a switching regulator,
always ground the frame ground terminal and the ground terminal.
● Operating Environment
Ambient Atmosphere
• Although the Sensor is water resistance, it is a capacitive sensor
and should not be used where it will come into direct contact with
liquids, such as water or cutting oil.
• The life of the Sensor will be shorten by rapid changes in
temperature even within the ambient operating temperature range.
Do not use the Sensor in locations subject to rapid temperature
changes.
● Miscellaneous
Drift will occur when the power supply is turned ON. If the specific
inductive capacity of the sensing liquid is low, the detection level may
increase by 2 to 3 mm during the 20 minutes required from the time
the power supply is turned ON until operation stabilizes.
