It is also used for many types of signal connections like: Serial digital interface and analog signals High-tech video networks Amateur radio antenna connections Electronic test equipment Aviation electronics or avionics The BNC connector is widely used in electronics although it is being superseded by the LEMO 00 mini-connector that handles higher densities.
BNC connectors can connect both analog and digital signals. Male type BNC connectors are attached to the ends of coaxial cables. BNC connectors consist of metal ring, or tube, surrounding a pin. The pin is connected to the coaxial cable and is the point of transmission between the cable and the device the cable is connected to.
This type of connector by its nature can cope with a limited range of cable sizes and requires no specialised tooling to assemble. This makes it ideal for small quantity production, either for one off cables for laboratory use of for limited production runs. The crimp BNC connector has the centre pin which is normally crimped to the centre conductor.
This crimped pin is then pushed into position through an inner ferrule which separates the inner insulation sheath and the braid of the cable. An outer ferrule is then crimped over the braid and outer insulation which fixes the cable to the connector. Greater accuracy is required for the crimp style connectors and therefore the correct connector variant must be chosen for the cable being used.
This may result in a crimp style connector not being practicable for some cable types. In addition to this the assembly requires the use of the correct crimping tools to ensure that the connector is correctly crimped. While these connectors are always preferred for large production runs because they are much faster to assemble, it is not possible for them to be reworked for obvious reasons.
For both styles of BNC connector it is essential that the exact amount of insulation is stripped from each section to ensure accurate assembly and the required RF performance.
Finally a variety of BNC adapters and other ancillary items are available. One popular BNC adapter is the straight through adapter, allowing two cables with male connectors fitted to be connected end to end. Other "T" adapters are also available. These have a male plug at the bottom of the "T" and two female connections at either end of the horizontal of the "T". These are ideal for use with oscilloscopes where a through connection needs to be measured, and the "T" BNC adapter enables the required connections to be made.
In addition to this a variety of inter-series adapters are available to enable transitions to be made between different connector types. These inter-series connector adapters can be very useful as it is not uncommon for two or more varieties of connector to be used in a laboratory or work area.
It is easy and convenient to use, it is robust, cost effective, and relatively easy to assemble, although a little care is needed.
