N plug (RG-213) UG-21/U

N connectors are among the most commonly used connectors in radio technology, they are available for practically all cables. The advantage is the robustness and simple assembly without special tools (except for crimp connectors). N-connectors are largely waterproof when mounted correctly. The N connectors we offer are nickel-plated and have a gold-plated inner conductor.

So-called RP-N connectors are occasionally used in the WLAN sector. RP stands for Reverse Polarity, i.e. the inner conductor has a reversed polarity. Instead of a pin, one finds a cup and vice versa. This confuses the terms plug and socket - usually everything with an external thread is called a socket, everything with an internal thread is called a plug, regardless of what the internal conductor looks like. This is explained in more detail and with pictures on our WLAN pages.

Many of the plugs offered here are crimp plugs. This means that they are not soldered on, but the outer braiding is placed on a shaft, a sleeve is placed over it and this is then pressed shut with a special crimping tool. The inner conductor is usually always soldered. We are happy to supply the necessary tools:

If you want to crimp the connectors yourself, you need the exact dimensions to which the outer sheath, the outer conductor and the dielectric must be cut. You can find these dimensions in the following file in the download area above: Kabel-Längenmaße für Crimpstecker (PDF, 173KB)

We are also happy to offer customised cable production.
