Amphenol RFBNCBNC ConnectorsDescription Developed in the late 1940’s as a miniature version of the Type C connector, BNC stands for Bayonet Neill Concelmanand is named after Amphenol engineer Carl Concelman. The BNC product line is a miniature quick connect/disconnectRF connector. It features two bayonet lugs on the female connector; mating is achieved with only a quarter turn of thecoupling nut. BNC’s are ideally suited for cable termination for miniature to subminiature coaxial cable (RG-58, 59, toRG-179, RG-316, etc.)Amphenol 50 Ω BNC connectors are miniature, lightweight units useable up to 11 GHz and typically yield low reflectionthrough 4 GHz. Designed to accommodate a large variety of RG and industry standard cables, BNC connectors are available in crimp/crimp, clamp/solder, SURETWIST , and field serviceable termination styles. A full line of printed circuit boardreceptacles, bulkhead receptacles, resistor terminations, and other accessories complement the product offering.A variety of our 50 Ω BNC connectors are recognized under the Component program of Underwriter’s Laboratories, Inc.These connectors are ideal for use with medical equipment and test instrumentation where safety cannot be compromised.Amphenol also offers a full line of 75 Ω BNC connectors to meet the needs for higher performance impedance-matchedcable interconnections. These connectors can be used in a variety of applications where true 75 Ω performance is neededto insure low signal distortion. Designed for the most popular 75 Ω cables used in broadcast and telecommunicationsapplications as well as for plenum and other cables, these connectors feature crimp-crimp cable affixment for quick andreliable installation.Part numbers that are listed with the appropriate M39012 number are military grade connectors produced in accordancewith and actively qualified to the military specification MIL-C-39012. Connectors not listed with the M39012 numberconstitute the industrial grade product offering. These connectors provide comparable performance and generally featurenickel-plated brass bodies, Teflon insulators, and either gold or silver-plated center contacts. Amphenol’s commercial gradeconnector offering carries the part number designation “RFX” for easy recognition. These low-cost connectors typicallyutilize die cast and molded components.Reverse Polarity BNC’s are also available. Reverse polarity is a keying system accomplished with a reverse interface, andensures that reverse polarity interface connectors do not mate with standard interface connectors. Amphenol accomplishesthis by inserting female contacts into plugs and male contacts into jacks. Other manufacturers may use reverse threading toaccomplish reverse polarity keying.Features/Benefits Bayonet coupling mechanism provides quick mating and unmating 50 Ω and 75 Ω impedance designs allow customers to match systemrequirements 50 Ω and 75 Ω connectors are intermateable Four grades of connectors are available for military, industrial, commercial and performance applicationsApplications Antennas Base Stations Broadcast Cable Assemblies Computers/LANs Radios Satellite Communications106BNCDownloaded from Arrow.com.
