Proximity Sensors: For Outdoor Usage

FAQ No. FAQ00380

Primary Contents


Are Proximity Sensors that can be used outdoors available?


Proximity Sensors that are used outdoors may not last.


Degradation of Resin Material Due to Ultraviolet Light

The environmental resistance (i.e., water resistance) of Proximity Sensors may be degraded because of degradation of the internal filling resin, sensing surface resin material, or cable sheath due to ultraviolet light.

Stress on Filling Resin Due to Sudden Temperature Changes

Rapid changes in temperature that accompany exposure to direct sunlight or changes in weather may cause swelling and shrinking of internal filling resin and other stress on Sensors.

Degradation of Resin Due to Freezing

Freezing of Proximity Sensors may cause cracks in the resin material of the sensing surface and degrade the environmental resistance (i.e., water resistance).


Proximity Sensors can be used with a hood or installed in a resin box to prevent exposure to ultraviolet light and freezing.
