=|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 provide a minimum distance between the two sensors, as below charts.

=|Materials 

OMaterials of sensing targets 

OEffect by high frequency electrical field It may cause malfunction by machinery which generate high frequency of electrical field such as a washing machine etc. 

OSurrounding environment 

There is water or oil on surface of sensing part, it may cause malfunction. If the bottle for detecting 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. OOil 

Do not let the oil or oil liquid is flowed into the sensor, the case is made by plastic.
