Twinax Connectors

Twinax connectors, also called twin Bayonet Neill-Concelman (BNC) connectors, are used in balanced low level and high level sensitivity circuits to prevent signals from being mixed. These connectors ensure system integrity through a feature called keyway polarisation. Twinax connectors have a bayonet latching shell and contain male and female contact points. The bayonet design allows for quick and easy coupling. Twinax connectors have crimp contacts to ensure lower installation costs.

What are twinax connectors used for?

Twinax connectors are used for 78, 95 or 100 Ohm twinaxial conductor cables. These connectors can operate in a range of 0-200 MHz. Twinax connectors are standard in the broadband internet, military and instrumentation fields.

Types of twinax connectors

Twinax connectors are suitable for either cable attachment or panel mount configurations. They come in bulkhead and cable mount styles. They're available in standard (BNC), miniature and subminiature sizes.

Twinax connectors come in various solder / clamp and crimp assembly versions. The interface models are 2-, 3- and 4-lug bayonet as well threaded. Unique features like pin and socket, keying and polarisation are also available.
