Electric Capacitive type
Mutual-Interference & Influence By Surrounding Metals
When several proximity sensors are mounted closely, malfunction of sensor may be caused due to mutual interference.
Therefore, be sure to keep a minimum distance between the two sensors as below charts.
When sensors are mounted on metallic panel, you must prevent the sensors from malfunction by any metallic object.
Therefore, be sure to keep a minimum distance as below charts.
Sensing distance may be different by electrical characteristic of sensing target(conductivity, non dielectric constant)
and status of water absorption, size etc.
It may cause malfunction by machinery which generate high frequency of electrical eld such as a washing machine etc.
There is water or oil on surface of sensing part, it may cause malfunction.
If the bottle for sensing of level is coated by oil etc., it may cause malfunction.
Especially, 15mm type has high sensitivity for induced objects, please be careful of waterdrops.
Do not let the oil or oil liquid is owed into the sensor because the case is made by plastic.
