Product Description

BNC connectors are miniature quick connect/disconnect RF connectors. They feature two bayonet lugs on the female connector; mating is achieved with only a quarter turn of the coupling nut. BNCs are ideally suited for cable termination for miniature to sub-miniature coaxial cable types (RG-58, RG-59, to RG-179, RG-316, etc.)  See our Coaxial Cable Guide for additional cable types.

50Ω BNC connectors are miniature, lightweight units designed to operate up to 11 GHz and typically yield low reflection through 4 GHz. Designed to accommodate a large variety of RG and industry standard cables, BNC connectors are available in crimp/crimp, clamp/solder and field serviceable termination styles. A full line of printed circuit board receptacles, bulkhead receptacles, resistor terminations, and other accessories complement the product offering.

In addition to 50Ω ohm connectors, Amphenol Connex also offers 75Ω BNC connectors to meet the needs for higher performance impedance-matched cable interconnections. These connectors can be used in a variety of applications where true 75Ω performance (meeting SMPTE return loss requirements) is needed to ensure low signal distortion. Designed for the most popular 75Ω cables used in broadcast and CATV applications as well as for plenum and other cables, these connectors feature crimp-crimp cable affixment for quick and reliable installation.  Download our Broadcast Solutions Brochure for additional information.

Reverse Polarity BNC's are also available. Reverse polarity is a keying system accomplished with a reverse interface, and ensures that reverse polarity interface connectors do not mate with standard interface connectors. Amphenol Connex accomplishes this by inserting female contacts into plugs and male contacts into jacks.  To order a reverse polarized connector, add "RP" to most standard connector part numbers.
