A standard electronic plastic enclosure can meet requirements such as IP (protection class) or IK. It may contain a mounting element such as a pin tray.
The IP Standard is a standard for sealing against solids and liquids. The first number expresses the tightness against solids and the second number against liquids. The most common standards are:
IP 54 :
5 = Protected against dust and other microscopic residues
4 = Protected against strong water jets from all directions (12.5 mm nozzle, distance 2.5 m to 3 m).
IP 64 :
6 = Fully protected against dust
4 = Protected against water spray from all directions
IP 65 :
6 = Fully protected against dust
5 = Protected against water jets from all directions (6.3 mm nozzle, distance 2.5 to 3 m, flow rate 12.5 l/min ±5%)
