BNC connectors were being commonly employed on 10base2 thin Ethernet community cables and network playing cards. BNC connections can also be present in recording studios. Electronic recording equipment uses the relationship for synchronization of various factors by means of the transmission of word clock timing indicators.
BNC tee connectors with resistive load terminators The BNC connector is useful for analog composite video clip and digital online video interconnects on industrial online video gadgets. Purchaser electronics units with RCA connector jacks can be used with BNC-only industrial online video tools by inserting an adapter.
Portion by means of BNC and High definition-BNC connectors BNC connectors are generally Employed in electronics, but in certain applications they are now being replaced by LEMO 00 miniature connectors which allow for noticeably greater densities.
The BNC connector options two bayonet lugs on the feminine connector; mating is fully attained with a quarter change on the coupling nut. It works by using an outer conductor with slots and many plastic dielectric on each gender connector. This dielectric leads to increasing losses at greater frequencies. Over 4 GHz, the slots may radiate indicators, Therefore the connector is usable, although not automatically stable, up to about eleven GHz.

BNC equipment are usually mild body weight, made from stainless steel, and also have screw driver variety plastic cope with grips for implementing torque. Their shafts are usually double the duration of an ordinary connector.
BNC connectors are most often designed in 50 and seventy five ohm versions, matched for use with cables of the same attribute impedance. The 75 ohm styles can sometimes be regarded because of the diminished or absent dielectric within the mating ends but This really is by no means trusted. There was a proposal while in the early 1970s for that dielectric material to get coloured red in 75 ohm connectors, and although this is sometimes applied, it didn't grow to be conventional.
It has a twist-to-lock design and style, where by two lugs on the feminine connector engage slots inside the shell on the male one.
Normally the male connector is fitted into a cable, and the female into a panel on machines. Cable connectors tend to be created to be fitted by crimping[9] employing a Exclusive ability or guide Instrument.
Rear of a video switcher having an variety of BNC connectors The BNC was originally suitable for armed service use and has received broad acceptance in online video and RF apps around two GHz.

Inside the USSR, BNC connectors have been copied as SR connectors. Due to recalculating from imperial to metric measurements their dimensions differ marginally from People of BNC. They are really nevertheless usually interchangeable with them, sometimes with force used.

The court docket located that Salati’s patent was invalid since he realized in the Navy’s BNC prior to his software date.[3]
The BNC connector is a miniature swift-join/disconnect radio-frequency connector for coaxial cable. It was introduced on military radio tools in the 1940s, and has because become broadly Utilized in radio units and as a standard variety of video connector.
Triaxial BNC connector Triaxial (often called triax) connectors really are a variant on BNC that carry a signal and guard and also floor conductor. These are typically Employed in sensitive Digital measurement units. Early triaxial connectors were bnc being designed with just an additional internal conductor, but later triaxial connectors also contain a three-lug arrangement to rule out an accidental compelled mating that has a BNC connector.
The SHV connector was developed as a safer option: it won't mate with everyday BNC connectors, along with the interior conductor is far more difficult to accidentally Speak to.
Adaptors exist to allow some interconnection alternatives amongst triaxial and BNC connectors. The triaxial can also be known as a Trompeter link.
