For years, arnotec, whose brands also include koax24, has been experiencing steady growth – also in terms of the number of employees.

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.

Koax24 Kabelkonfigurator

No-name or branded goods? You have the choice!

You can choose between BNC_farbig_konfektionassemblies, which are assembled exclusively with brands of well-known manufacturers, and assemblies by manufacturers, who are less well-known. This does not mean, that the quality of the connectors and the resulting cable assemblies are worse or worth less.

Example: BNC cable assembly by Telegärtner or by our alternative manufacturer
Price difference: 2.80 €

We check every batch of the connectors on technical parameters and pay close attention to …
