Connectors for coaxial cables are available in many varieties. There are various reasons for this, mostly special connectors were created for specific applications. Criteria were robustness and waterproofness (outdoor use, antennas), the possibility to disconnect and reconnect connectors very often quickly (laboratory and measurement technology), connectors for very high frequencies and with a small shape (device cabling) and of course the price.
This has resulted in a very wide variety of coax connectors over the last decades, exactly matching the respective application. In professional outdoor technology mostly N, C or 7/16" connectors are used, in indoor applications BNC or SMA, in industrial communication systems often TNC, for amateur radio use very often PL (SO-239). The explosive boom in the Wifi area has led to many more types. Because the inner conductor was exchanged, so-called "reverse polarity" connectors developed.
One last criteria is the assembly technique - coax connectors are either soldered, screwed or crimped.
A coax plug must fit exactly for the respective cable type. This is especially true for crimp connectors. Here, a deviation of a few tenths of a millimetre is already decisive as to whether a connector fits the cable or not.
WiMo offers a very large selection of coaxial plugs of all types and for many cable diameters. We are happy to help you with your selection.
