> 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) |
> Class :
| CLASSE 1 | CLASSE 2 | CLASSE 3 | |
| Main characteristics of the material | Protection by earth connection | Supplementary insulation but no means of protection by earth connection | Used for power supply by extra low voltage of security (lower or equal in 50V) |
| Security precautions | Connection to earth protection | No necessary precaution | Connection to extra low voltage of security (TBTS) |
