> IK codes :

Shock protection :  IK Code. It is a code system to indicate the cover required protection level against harmful mechanical impacts.

The IK code refers to the protection level. It is indicated as follows:
Each group of characteristic figures refers to the impact energy value, as indicated in the opposite table :

 CODE IK  00  01  02  03  04  05  06  07  08  09  10
 Shock energy (Joule)  0.15  0.20  0.35  0.50  0.70  1.00  2.00  5.00  10.00  20.00

> IP rating protection:

First number: protection degree against solid substances
Second number: protection against liquid substances

 IP 20  IP 40  IP 54 IP 65
Protected against solid substance over 12mm Protected against solid substance over 1mm Protected against dust
Protected against water splashings from all directions
Completely protected against dust
Protected against water splashings from all directions (0,3 bar of pressure to a distance of 3 meters)
