BNC connectors are very common among other RF connectors that are used with various coaxial cables for connecting mostly video or audio radio-frequency electronic equipment such as surveillance cameras, for example.
They use bayonet-type locking system which provides secure connection but a bit harder to connect comparing with RCA plugs. These connectors have good impedance characteristics.
BNC connectors are small in size made for rather quick bayonet-type connecting and disconnecting operations requiring just one quarter turn.
These connectors got their name from 2 engineers: Paul Neill from Bell Labs and Carl Concelman from Amphenol. Bayonet-Neill-Concelman was used to create an abbreviation for BNC connectors.
These connectors have center pins that are connected to the center cable conductors. Metal tubes of BNC connectors are connected to the outer cable shields.
They are manufactured in 2 different versions each matching cables of the same characteristic impedance: 50 ohm version and 75 ohm version.
Both versions of connectors can mate with each other.
50 ohm version is used primarily for RF and data applications. 75 ohm BNC connectors are used mostly with video equipment.
BNC connectors are available in clamp, crimp and twist-on cable styles.
For inserting and removing BNC Connectors in hard-to-reach areas a BNC tool is used.
Below are the main types of BNC connectors that we have in stock.
