Coaxial Connectors

Coaxial connectors are necessary for a coaxial cable to connect it to a device, such as a WiFi antenna. Depending on the cable and component as well as the usage requirements, different types of connectors must be used, which can be connected by crimping, soldering or clamping to the coaxial cable. You can easily mount the coax connectors from our online shop with the help of a suitable crimping tool. Our plugs fit the high-frequency RF240, H155 and RF5 coaxial cable types, which are often used for WiFi. The plugs must be selected to match the socket of the device to which the cable is to be connected and vice versa. Basically, the male component of a connector consists of an inner conductor pin, a closure (for turning, plugging, etc.) and an insulating outer material. The female component has an inner conductor tube. Both components are usually also available as a reverse version, then with an inverted polarity. Which connector type you need, you can ask our customer service. There you will also receive detailed instructions for correct installation.

Different coax connectors
SMA: The SMA connector, espacially the reverse version is one of the most commonly used connectors in the area of WiFi. It has a sturdy screw cap and, depending on the series, can still be safely used in the extremely high-frequency range up to 18 GHz. The impedance is 50 ohms for SMA and RP-SMA (reverse polarity). An SMA connector has a union nut for mounting, while the corresponding SMA connector is equipped with an external thread. Thus, the two components can be easily connected to each other and are subsequently securely and stably bolted. Most of the WiFi devices have reverse SMA sockets. These were originally intended to complicate the mounting of an external antenna and thus to keep the market for such components small. However, this was only little success, because in a short time appropriate plugs and adapters were produced, which circumvent this problem simply and inexpensively. Therefore, make sure that your device is an SMA or RP-SMA connector. This can only be detected in the released state, since the two plug connections are identical externally. In RP-SMA, the plug is equipped with an inner conductor tube, while the socket is equipped with a pin.

N: The N connectors are mainly used in the professional field of high frequency technology and have been used since the 40s in the Navy. Whether their name derives from this (Navy Connector) or from their developer Paul Neill, is not finally clarified. They are mounted by a screw lock, the impedance is either 50 or less often 75 ohms. The plugs have an inner conductor as a pin (male), the jacks on an inner conductor in tube form. N connectors can be used up to a frequency of 11 GHz.

TNC: TNC (Threaded Neill Concelman or Thread Navy Connector) connectors are a much used series in the field of connectors. They differ from their predecessor BNC only by a different closure. The name-giving bayonet closure of the BNC proved especially in vehicles or under exposure to vibration not the desired stability, which is why it was replaced by a threaded screw cap. The TNC is as RP-TNC is also available in the reverse version and can be used with a characteristic impedance of 50 ohms for high frequencies up to a maximum of 18 GHz.

FME: FME connectors are usually connected to the matching RG 58 coaxial cable and connect cellular antennas in vehicles as well as external antennas. The internal resistance is standard at 50 ohms at frequencies up to about 2 GHz. FMEs are among the miniature connectors and their special design also makes them suitable for narrow cable entries: unlike other regular connectors, the FME is the female component, ie the socket with tube, with a union nut, the male component (plug with pin) with an external thread.
