![]() Impedance refers to the level of electrical resistance in the wire. Gauge refers to the thickness of the cable and is given a given a Radio Guide or RG number, with higher numbers indicating thinner conducting cores. These include:Ĭoaxial cables are available in a variety of types, distinguished by their ‘gauge’ and ‘impedance’. Coaxial cables are the default cabling choice for many low voltage consumer electronics. Their design allows rapid signal transmission (around 10 megabits per second) with minimal electro-magnetic interference or signal loss. They contain an inner conducting wire, usually copper, surrounded by a protective double insulating layer and then an outer plastic sheath, giving them a distinctive appearance.Ĭoaxial cables are durable, easy to install, and have a broad range of uses. if a male or female connection is necessary.Coaxial or ‘coax’ cables are electrical cables created to carry high frequency, multi-megahertz electrical signals.Knowing the essential characteristics of the cable you intend to connect is necessary when choosing a coaxial connector.

These cables each have a male connector with a ring around it. ![]() These cables, which are also known as A/V jacks, are the familiar red, white, and yellow cords that plug into the back of televisions. The Radio Corporation of America connector, also referred to as a “cinch connector,” was initially created for the transmission of audio signals but is now widely used in video as well. Today’s N-series connectors come in reverse polarity and are capable of handling frequencies of up to 18 GHz. 75 oh versions do exist today, but they are much less common and incompatible with the 50 ohm version. The Paul Neill-invented N-series connector is a 50 ohm connector that was first created for military applications. The snap-on coupling design on MCX connectors makes installation quick and hassle-free. In wireless, GPS, TV tuner cards, RF hardware, and digital cellular applications, MCX connectors operate between DC and 6 GHz and have an outer diameter that is 30% smaller than that of SMB connectors. ![]() Micro coaxial connectors are small-form-factor connectors that are perfect for applications requiring minimal weight, size, or space. The female inner contact’s inner diameter is 7 mm, and the outer contact’s overall inner diameter is 16 mm, as indicated by the connector’s name. It can be tightened with a wrench and operates at up to 7.5 GHz. 7/16 DINįor high-wattage transmissions in cellular networks, antenna systems with multiple transmitters, and defense applications, the 7/16 DIN (Deutsches Institut für Normung) connector is a threaded RF connector. They provide a straightforward snap-on coupling design for semi-rigid cables with infrequent connections. For industrial and telecommunications equipment, SMB connectors are among the most widely used RF/microwave connector variations. ![]() Smaller versions of SMA connectors called subminiature version B connectors offer better electrical performance from DC to 4 GHz. To address leakage and stability problems in cellular phone and RF/antenna connections, TNC Connectors are small, weatherproof devices that operate up to 12 GHz. The threaded Neil-Concelman performs better at microwave frequencies than BNC connectors because it is a threaded version of a BNC connector. QMA connectors are perfect for industrial and communications applications as well as cable wiring, assembly, and repair because they offer faster and safer coupling as well as excellent performance in RF connections. QMA connectors share the same internal architecture as SMA connectors and are a quick-lock and quick-disconnect variant. BNC connectors have two bayonet lugs for a twisting interface on the female connector and are best suited for frequencies below 4 GHz because connectors become less mechanically stable as frequencies above 10 GHz approach. It was initially created for military use. The Bayonet Neil-Concelman (BNC) coaxial connector is a miniature-to-subminiature RF connector used for fast connect/disconnect in RF equipment, test instruments, radio, television, and video signal. Read More: Audio Connectors Types of Coaxial Connectors BNC Some have switches that enable internal batteries to be unplugged when an external power source is connected. They come in a wide range of sizes to fit various cable dimensions, and each one works in concert with the others to guarantee signal transmission without interruption. When connecting devices to external power sources or connecting cables to one another, coaxial connectors, also known as barrel or tip connectors, are used to top and tail the cables and maintain the outer interference shielding.
