Coaxial Connectors

Coaxial connectors are used to connect a coaxial cable to another component, such as a WiFi antenna. Depending on the cable, component, and usage requirements, various connector types can be used, connected to the coaxial cable through crimping, soldering, clamping, or insertion. The connectors from our online shop can be easily assembled using an appropriate crimping tool. Our connectors fit the high-frequency coaxial cable types RF240, H155, and RF5, commonly used in WiFi. The connectors must be selected to match the socket of the device to which the cable will be connected and vice versa. In general, the male component of a connector consists of an inner conductor pin, a locking mechanism (for twisting, plugging, etc.), and an insulating outer material. The female component has an inner conductor tube. Both components are usually also available as a reverse variant, with reversed polarity.

Feel free to inquire with our customer service about which connector type you need. They can also provide detailed instructions for correct assembly.
 

Various Connector Types:

SMA (Sub Miniature A): The SMA connector is one of the most commonly used connectors in the WiFi domain. It features a robust screw lock and, depending on the series, is safely applicable even in the extremely high-frequency range up to 18 GHz. The impedance is 50 ohms for both SMA and RP-SMA (Reverse Polarity). An SMA connector has a coupling nut for assembly, while the corresponding SMA socket is equipped with an external thread. This allows the two components to be easily connected and securely screwed together. Many WiFi devices have Reverse SMA sockets, originally intended to make attaching an external antenna more challenging and thus keep the market for such components small. However, this was met with little success, as corresponding connectors and adapters were quickly produced to bypass this problem easily and cost-effectively. Therefore, pay attention to whether your device has an SMA or RP-SMA connector. This can only be recognized in the disconnected state since the two connectors look similar externally. For RP-SMA, the connector has an inner conductor tube, while the socket has a pin.

N Connector: N connectors are widespread in the professional field of high-frequency technology and have been used in the military since the 1940s. Whether their name comes from "Navy Connector" or their developer Paul Neill is not definitively clarified. They are mounted through a screw lock, with an impedance of either 50 or, more rarely, 75 ohms. The connectors have an inner conductor as a pin (male), and the sockets have an inner conductor in tube form. N connectors can be used up to a frequency of 11 GHz.

TNC (Threaded Neill Concelman): TNC connectors are a widely used series in the connector domain, distinguishing themselves from their predecessor BNC only through a different locking mechanism. The BNC's bayonet lock proved insufficient, especially in vehicles or when subjected to vibrations, leading to its replacement with a threaded screw lock. The TNC is available in a reverse version as RP-TNC and, with a wave impedance of 50 ohms, can be used for high frequencies up to a maximum of 18 GHz.

FME (For Mobile Equipment): FME connectors are mostly connected to the corresponding RG 58 coaxial cable, linking mobile antennas in vehicles with external antennas for WiFi devices. The default inner resistance is 50 ohms at frequencies up to about 2 GHz. FMEs are classified as miniature connectors and are well-suited for tight cable penetrations due to their special construction: Unlike other regular connectors, in FME, the female component (socket with tube) has a coupling nut, while the male component (connector with pin) has an external thread.
