IP protection classes and their meaning
Several ICY BOX and KeySonic products have a so called IP protection class (. IP54 or IP66). This IP indication specifies the level of protection against certain environmental conditions, particularly against foreign particles (. dust) and water.

The IP protection classes are defined by two digits and are subdivided into different levels. While the first digit specifies the protection against foreign particles, the second digit defines the degree of protection against moisture.

IP protection classes:

Level      Meaning
0               No protection
1               Protection against objects with a diameter > 50 mm
2               Protection against objects with a diameter > mm
3               Protection against objects with a diameter > mm
4               Protection against objects with a diameter > mm
5               Dust protected
6               Dust tight

Level      Meaning
1               Protection against dripping water
2               Protection against dripping water when tilted up to 15°
3               Protection against spraying water
4               Protection against splashing of water
5               Protection against water jets
6               Protection against powerful water jets
7               Protection against temporary immersion
8               Protection against permanent immersion
9               Protection against high-pressure cleaning / steam cleaning

This means that the external ICY BOX enclosure IB-276U3 with protection level IP66 is dust tight and protected against powerful water jets .

In addition to the dust and water proof IB-276U3, there is the IB-278U3 (IP54) and the IB-279U3 (IP65), all of which are external enclosures for " drives. Regarding KeySonic keyboards mainly those from the industrial line (like KSK-5230IN) comply with IP68 protection class.
