BNC Connectors

BNC Connectors

BNC
BNC connector types feature a bayonet style coupling mechanism that allows for quick connect and disconnect with positive locking. Mating is achieved with just a quarter-turn of the coupling nut. With a classic, dependable design, BNC RF connectors are suited to accommodate a large variety of RG and industry-standard coaxial cables, in a variety of termination styles.

What is a BNC Connector?

The Bayonet Neill Concelman (BNC) connector was developed by Paul Neill of Bell Labs and Amphenol's own, Carl Concelman, and was named after both inventors and the innovative bayonet locking mechanism that the connector utilizes. The BNC connector was originally designed for military applications but is mostly used in the broadcast market today. This connector has evolved to keep up with the changing landscape of the industry and now provides 12G SDI performance that is required in 4K and Ultra-HD applications. BNC connector types designed for coaxial cable have been widely adopted and continue to be a popular choice for existing and next-generation video technology.

Amphenol RF offers a full line of BNC connectors types in a multitude of female and male options. BNC connectors are miniature, lightweight and reliable. 50 ohm BNC and 75 ohm BNC connectors are available in configurations ideal for commercial and military-grade applications. A full line of printed circuit board (PBC) receptacles, bulkhead receptacles, reverse-polarity connectors, resistor terminations, and other accessories complement the product offering.
