Service is important to us and part of our corporate culture. That is why we provide you with useful information about the technical terms and abbreviations used in our catalogue on this site. We also offer you information on the degrees of protection described in the catalogue and valuable information on how to determine the X-dimension.

The levels of protection are indicated by an abbreviation (IPxy), which is composed of the two constant code letters
IP (international protection) and two index numbers for the level of protection.
first index number x: level of protection for protection against contact and foreign bodies
second index number y: level of protection for protection against harmful ingress of water

IPxy index number x index number y
IP00 no protection against contact and foreign bodies no water protection
IP20 protection against solid objects greater than 12 mm greater than 1 mm no water protection
IP40 protection against grain-shaped solid objects no water protection
IP44 protection against grain-shaped solid objects greater than 1 mm front side protection against splashing water from all directions
IP54 protection against dust front side protection against splashing water from all directions
IP65 protection against dust ingress protection against  water jets from all directions
IP67 protection against dust ingress protection against immersion (in depths from 150 mm until 1000 mm no detrimenta quantity of water may ingress with time limitation)
