BNC Connector

The golden oldie BNC connector. Ideal for quick connects to audio coax and high-frequency signal lines. We thought BNC stood for British Naval Connector. The Wikipedia definition has it listed as the *Bayonet Neill Concelman *connector. Boy were we wrong!

Comes with lock washer and nut.

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

2 Soldering

Skill Level: Rookie - The number of pins increases, and you will have to determine polarity of components and some of the components might be a bit trickier or close together. You might need solder wick or flux.

  • The other names are not "definitions" for the acronym BNC. They are nicknames or perhaps mnemonics used to remember the letters B,N,C.
    If you go to Amphenol's site, they tell you what the real name is.
    Paul Neill of Bell Labs and Carl Concelman of Amphenol, collaborated to develop the BNC connector, and it was named after them and its locking mechanism.
    Neill had formerly invented the N connector and Concelman had invented the C connector.
    The incorrect names are copied and repeated hundreds of times on the Internet, but it doesn't make them correct.

  • Sparkfun, you guys think you'll ever carry male, crimp versions of these? for making cables and such?

    • unfortunately, probably not. we don't sell a lot of these and they're a bit hard to find.

  • I know i'm going to submit a trivial question...
    I never used a bnc connector. I'm going to use it for a 3 cable temperature sensor. How do I solder the 3 cables to the bnc connector ?

    • Assuming you've got other cables for the power (both VCC and GND connections), a BNC cable would do a great job of transmitting the analog signal without allowing extra noise. Connect the shield to ground, and use the center terminal for the low-level, noise-sensitive analog connections.

    • you don't. it only supports signal and ground.

  • There are numerous definitions of the BNC acronym, including Bayonet Neill-Concelman (after its inventors), Barrel Nut Connector, Bayonet Nipple Connector, Bayonet Navy Connector, Baby N Connector, British Naval Connector and British National Connector. See A/V ports, coaxial cable and plugs & sockets.
