*() is for Normally closed type. 

## (a]Grounding 

The sensing distance will be changed by grounding status of capacitive proximity sensor and the target [50 x 50 1mm (ron) ]. Please check the material when installing it on panel.

=|Mutual-interference & Influence by surrounding metals 

When several proximity sensors are mounted close to one another a malfunction of the sensor may be caused due to mutual interference. Therefore, be sure to provide a minimum distance between the two sensors as below chart indicates.

=|Materials 

OMaterials of sensing targets 

Sensing distance may be different by electrical characteristic of sensing target (conductivity, non dielectric constant) and status of water absorption, size etc. 

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 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. OOil 

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