IP protection types for coaxial connectors

What are IP protection types?

The abbreviation IP stands for International Protection or also Ingress Protection (protection from intrusion). In our case, the protection class for coaxial connectors provides information about their suitability for certain environmental conditions. This classification clearly clarifies whether a connector is suitable for outdoor use, for example, or whether it could be damaged by penetrating moisture. Incidentally, similar requirements for cables are explained in the article “Jacket materials for coaxial cables”. The individual protection classes are defined within Germany according to DIN and internationally according to ISO.

How is the IP code composed?

Fire properties of coaxial cables

Many coaxial cables are designed to withstand high temperatures of up to 200°C without damage. These usually have a dielectric made of PTFE and an outer sheath made of FEB, PFA or PTFE. Cables with a dielectric and sheath made of Kapton are even temperature-resistant up to 250°C.


Please note: If temperature-resistant cables are assembled with the matching connectors and bend protectors, the maximum temperature is always that of the component with the lowest temperature resistance. If the coaxial cable is suitable for temperatures up to 200°C, but the connectors are only suitable for temperatures up to …

Chemical resistance of coaxial cables

It is not uncommon for a coaxial cable to be exposed to substances that can possibly impair its effect. In this case, it is useful to know the chemical resistance of the material in order to select the right cable for your application in advance. As you can see from the table below, in addition to the sheath material of the cable, the temperature of your application is also crucial. This is due to the fact that the structure of plastics changes at different temperatures. The most common plastics of our cable sheaths are considered here: PVC and PE. You …
