BNC Connector (75 Ohm)

What are the different types of BNC connectors?

There are basically two versions: 50 ohm and 75 ohm connectors. Their use is related to video and radio frequency functions. 75 ohm BNC connectors are used specifically for video cameras. BNC connectors can also be used as an alternative to RCA connectors on devices capable of transmitting composite video signals.

There are different types:

• Crimp connectors. BNC crimp type connectors must be pressed on with pliers for a stable fixing.
• The BNC type connectors must be of the twist-on type. If you choose a solderable version, it is essential to use a soldering iron.
• Straight or 90 degree connectors. We also offer straight or "elbow" types.
• Connectors with built-in sockets. These PCB mountable connectors are useful if you want to incorporate them into your electronic devices.

Why BNC connectors with 50 and 75 ohms?

Coaxial cables with 50 and 75 ohm resistance provide optimum power handling and minimal signal loss, making them great for transmitting video signals. In the first half of the 20th century, 30 ohm cables were also experimented with, which provided basically adequate power and voltage handling, but required higher resistance, i.e. more ohms, to achieve sufficiently low attenuation. Today, these are the two most widely used standards.

How is the 75 ohm design better?

It is most commonly used for cable TV and security cameras, but 75 ohm coaxial cables can also carry audio, making them a great choice for home theatre systems.

What should you choose 50 ohm for?

For measuring instruments and amplifiers, and other test equipment. If you're not specifically talking about video or audio transmission, you should opt for 50 ohm connectors, which offer better signal amplification performance. These BNC plugs and cables are used up to 4 Ghz and are widely used for analog video signal transmission. It is important to note, however, that 50 ohm plugs and cables do not produce a crystal clear picture, so if picture quality is important, 75 ohm products are the solution.

Is BNC technology still popular today?

Yes, BNC sockets and coax cables are still in use today Although they had their heyday in the 1990s and 2000s, they are still widely used for SD and HD video signal transmission. Interestingly, decades ago BNC converters and cables were still used to transfer signals between computers, but today you see fewer and fewer of them in workplaces and homes. However, BNC technology still offers the same reliable performance as it did in the 1990s, the golden age of cable TV.

We offer BNC connectors in socket, nut and crimp and other types!
