![]() ![]() We also offer custom made coaxial cables, please see here. You can find these dimensions in the following file in the download area above: Kabel-Längenmaße für Crimpstecker (PDF, 173KB) 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. Of course we supply the required tools as well, please see Crimp tools. That means that these connectors are not soldered but that the outer shield is pressed onto the shaft of the connector with a special tool. Most of the connectors offered here are crimp connectors. ![]() SMA connectors are usually made from machined. On our website Wifi connectors this is explained in greater detail and with pictures. SMA connectors consist of a quarter-inch (6.35 millimeter) diameter barrel with 36 threads per inch threading. Usually all connectors with an outside thread are called a jack, all with a nut with inner thread are plugs, regardless of the polarity of the center conductor. This leads to quite some confusion about what is a plug and what is a jack. Instead of a male conductor you find a female contact and vice versa. That means that the center conductor has an inversed polarity. The SMA connectors offered here have a gold plated center conductor and nickel plated exterior.įor Wifi equipment (wireless LAN) often so called reverse polarity, or RP-SMA connectors are used. SMA connectors can be used up to frequencies of more than 14GHz, depending on the model of the connector. Most amateur radio handheld radios do use a SMA female connector. SMA connectors are used for device internal cables as well as external antenna connectors for small antennas. ![]() Frequency Counter, Near Field Receivers.Morse keys, electronic keyers, accessories.Stationary, directional antennas (Yagi, X-Quad).Type F connectors look similar but are of slightly different size and will not pair with SMA or RP-SMA connectors without an adapter. SMA connectors are not compatible with the common, commercially available Type F coaxial connector. The male connector has a hex nut that fits securely around the female barrel for a tight coupling. The female connector has a threaded barrel with a density of 36 threads per inch. SMA connectors are not compatible with the common, commercially available Type F coaxial connector. The SMA connector (Sub-Miniature Version A) is a semi-precision RF coaxial connector with a screwing coupling feature. WiFi antennas, LTE, GSM & CDMA antennas, 433MHz antennas.Common applications of SMA connectors and cables: The connectors have a coupling cycle of 500 times, which can only be achieved by applying the recommended torque while coupling. Both male and female connectors use polytetrafluoroethylene (PTFE) dielectric. SMA connectors have an impedance of 50 Ohms used from DC to 18GHz. Connectors are made out of stainless steel or brass, coated with nickel or gold around the contacts. This coupling is fairly secure and has an outstanding mechanical durability. ![]() The SMA connector (Sub-Miniature Version A) is a semi-precision RF coaxial connector with a screwing coupling feature. This reversing is done on some equipment where there is a danger that the user might damage the connectors wile coupling due to their position or repeated mating. Standard SMA and RP-SMA connectors are not compatible. Similarly, the female has a central pin rather than a receptacle.
