Use

The BNC connector is used for professional video connections, both for analog and Serial Digital Interface signals, amateur radio antenna connections, aviation electronics (avionics) and on nearly every piece of electronic test equipment manufactured in the last 35 or so years. This connector is an alternative to the RCA connector when used for composite video on commercial video devices, however many consumer electronics with RCA jacks can be used with BNC-only commercial video equipment via a simple adaptor. BNC connectors were commonly used on 10base2 thin Ethernet networks, both on cable interconnections and network cards, though these have largely been replaced by newer Ethernet devices whose wiring does not use coaxial cable. Some ARCNET networks use BNC terminated coax. Video (Latin for I see, first person singular present, indicative of videre, to see) is the technology of electronically capturing, recording, processing, storing, transmitting, and reconstructing a sequence of still images representing scenes in motion. ... Analog video is a term that can refer to any of three analog television (picture only) transmissions signals. ...

Specifications

BNC connectors exist in 50 and 75 ohm versions. Typically, they are specified for use at frequencies up to 4 and 2 GHz, respectively. A multimeter can be used to measure resistance in ohms. ...


History

The connector was named after its bayonet mount locking mechanism and its two inventors, Paul Neill of Bell Labs (inventor of the N connector) and Amphenol engineer Carl Concelman (inventor of the C connector), and is much smaller than both the N and the C connectors. Other backronyms the BNC has picked up over the years include: "Baby Neill-Concelman", "Baby N connector", "British Naval Connector", and "Bayonet Nut Connector". A bayonet mount A bayonet mount before and after insertion A bayonet mount or bayonet connector is a fastening mechanism that relies on mated surfaces; a male side with one or more pins or slots, and a female receptor with matching slots and a spring that maintains a clamping force. ... Engineer at Bell Labs in the 1940s and 1950s credited with helping to invent the BNC, TNC and Type N connectors used for Microwave communications. ... Bell Laboratories (also known as Bell Labs and formerly known as AT&T Bell Laboratories and Bell Telephone Laboratories) was the main research and development arm of the United States Bell System. ... Type N connector (male) Type N connector (female) The N connector (in full, Type N connector) is a threaded RF connector used to join coaxial cables. ... Amphenol Corporation is one of the worlds leading producers of electronic and fiber optic connectors, cable and interconnect systems. ... Carl Concelman was the electrical engineer who, while working for Amphenol, invented the C connector and teamed up with Paul Neill of Bell Labs to invent the BNC connector. ... C connectors couple using two-stud bayonet-type locks. ... A backronym (or bacronym) is a phrase that is constructed backwards from the phrases abbreviation, the abbreviation being an initialism or acronym. ... Type N connector (male) Type N connector (female) The N connector (in full, Type N connector) is a threaded RF connector used to join coaxial cables. ...


The basis for the development of the BNC connector was largely the work of Octavio M. Salati, a graduate of the Moore School of Electrical Engineering of the University of Pennsylvania (BSEE '36, PhD '63). He filed a patent in 1945 (granted 1951) while working at Hazeltine Electronics Corporation for a connector placed on coaxial cables that would minimize wave reflection/loss.

A threaded version of the BNC connector, known as the TNC connector (for Threaded Neill-Concelman) is also available. It has superior performance to the BNC connector at microwave frequencies.

Microwaves are electromagnetic waves with wavelengths longer than those of terahertz (THz) frequencies, but relatively short for radio waves. ...


BNC connectors are commonly used in NIM electronics, but they are now often replaced by LEMO 00 miniature connectors which allow for higher densities. For higher voltages, MHV and SHV connectors are typically used. MHV connectors are easily mistaken for BNC connectors and can be made to mate with them by brute force. The SHV connector was developed as a safer alternative to MHV connectors and will not intermate with ordinary BNC connectors. Nim is a two-player mathematical game of strategy in which players take turns removing objects from distinct heaps. ... LEMO is both the name of an electronic and fibre optic connector manufacturer based in Switzerland, and the name commonly used to refer to connectors made by that company. ... The MHV (miniature high voltage) connector is a type of RF connector used for terminating coaxial cable. ... The SHV (safe high voltage) connector is a type of RF connector used for terminating a coaxial cable. ...


Twin BNC connectors use the same bayonet latching shell as an ordinary BNC connector but contain two independent contact points (one male and one female), allowing the connection of a 78 ohm or 95 ohm shielded differential pair such as RG-108A.[1] They are capable of operation at 100 MHz and 100 volts. Twin BNC connectors will not intermate with ordinary BNC connectors. Differential pair is a pair of conductors with special characteristics, used for differential signaling. ...
