The 75 ohm types can sometimes be recognized by the reduced or absent dielectric in the mating ends but this is by no means reliable. Types īNC connectors are most commonly made in 50 and 75 ohm versions, matched for use with cables of the same characteristic impedance. From left to right: 75 Ω female, 75 Ω male, 50 Ω female, 50 Ω male. Neill worked at Bell Labs and also invented the N connector Concelman worked at Amphenol and also invented the C connector. The connector was named the BNC (for Bayonet Neill–Concelman) after its bayonet mount locking mechanism and its inventors, Paul Neill and Carl Concelman. Wire strippers which strip outer jacket, shield braid, and inner dielectric to the correct lengths in one operation are used.

Cable connectors are often designed to be fitted by crimping using a special power or manual tool. Typically the male connector is fitted to a cable, and the female to a panel on equipment. Digital recording equipment uses the connection for synchronization of various components via the transmission of word clock timing signals. BNC connections can also be found in recording studios. BNC connectors were commonly used on 10base2 thin Ethernet network cables and network cards. Consumer electronics devices with RCA connector jacks can be used with BNC-only commercial video equipment by inserting an adapter. The BNC connector is used for analog composite video and digital video interconnects on commercial video devices.

They were commonly used for early computer networks, including ARCnet, the IBM PC Network, and the 10BASE2 variant of Ethernet.
BNC connectors are used with miniature-to-subminiature coaxial cable in radio, television, and other radio-frequency electronic equipment. The BNC was originally designed for military use and has gained wide acceptance in video and RF applications to 2 GHz. Use Rear of a video switcher with an array of BNC connectors The interface specifications for the BNC and many other connectors are referenced in MIL-STD-348. They are usually applied for frequencies below 4 GHz and voltages below 500 volts. BNC connectors are made to match the characteristic impedance of cable at either 50 ohms or 75 ohms (with other impedances such as 93 ohms for ARCNET available though less common). Above 4 GHz, the slots may radiate signals, so the connector is usable, but not necessarily stable, up to about 11 GHz. This dielectric causes increasing losses at higher frequencies. It uses an outer conductor with slots and some plastic dielectric on each gender connector. The BNC connector features two bayonet lugs on the female connector mating is fully achieved with a quarter turn of the coupling nut.
Similar radio-frequency connectors differ in dimensions and attachment features, and may allow for higher voltages, higher frequencies, or three-wire connections.
The type was introduced on military radio equipment in the 1940s and has since become widely applied in radio systems, and is a common type of video connector. The connector has a twist to lock design with two lugs in the female portion of the connector engaging a slot in the shell of the male portion. It is usually applied for video and radio frequency connections up to about 2 GHz and up to 500 volts. It is designed to maintain the same characteristic impedance of the cable, with 50 ohm and 75 ohm types being made.
