Amphenol® BNC Description Developed in the late 1940’s, the BNC is a miniature version of the Type C. BNC stands for Bayonet Neill Concelman and is available in 50 Ohm and 75 Ohm impedance versions. The BNC product line is a miniature quick connect / disconnect RF connector. It features two bayonet lugs on the female connector; mating is achieved with only a quarter turn of the coupling nut. Primary Applications - Ideally suited for cable termination for miniature to subminiature coaxial cable (RG-58, 59, to RG-179, RG-316, etc.) Features/Benefits 50 ohm BNC Cable Connectors • 50 and 75 ohm impedance designs allow customers to match impedance to system requirements. Specifications Cable Plugs Cable Jacks Receptacles PCB Receptacles Adapters Caps & Accessories • 50 and 75 ohm connectors are intermateable to ensure nondestructive mating. • Three grades of connectors are available for military, industrial and commercial applications.

BNC 50 ohm Coaxial Connectors Amphenol® Description Amphenol 50 ohm BNC connectors a re m i n i a t u re , l i g h t w e i g h t u n i t s designed to operate up to 11 GHz and typically yield low reflection through 4 GHz. Designed to accomodate a large variety of RG and industry standard cables, BNC connectors are available in crimpcrimp, clamp-solder, SURETWIST ®, and field serviceable termination styles. A full line of printed circuit board receptacles, bulkhead receptacles, resistor terminations, and other accessories complement the product offering. Features/Benefits Amphenol manufactures a full line of BNC connectors to meet all users’ needs. Parts which are listed with the appropriate M39012 number in t h e c a t a l o g a re M i l i t a r y G r a d e connectors produced in accordance with and actively qualified to the military specification MIL-C-39012. Connectors not listed with the M39012 number constitute the Industrial Grade product offering. These connectors provide comparable performance and generally feature nickel plated brass bodies, Teflon insulators, and either gold or silver plated center contacts. A m p h e n o l ’s C o m m e rc i a l G r a d e connector offering carries the part number designation “RFX” for easy recognition. These low cost connectors typically utilize diecast and molded components. While performance will not be equal to the Industrial or Military grade p ro d u c t s , t h e s e c o n n e c t o r s a re ideal for use on a variety of commercial applications. Amphenol’s 50 ohm BNC connectors (where indicated) are recognized under the Component Program of U n d e r w r i t e r ’s L a b o r a t o r i e s , I n c . They are ideal for use with medical equipment and test instrumentation where safety cannot be compromised. 50 ohm BNC 50 ohm Connectors 106 Plugs and Jacks 108-113 Adapters 119 PCB Connectors 120-121 Applications • Computers/LANs • Test and Measurement • Medical Equipment • Telecommunications • Wireless/Networks Amphenol Corporation Tel: 800-627-7100 www.amphenolrf.com 106 ELECTRICAL MECHANICAL ENVIRONMENTAL Impedance 50 ohms nominal ■ Frequency range 0-4 Ghz w/low reflection Voltage rating 500 volts peak Dielectric withstanding voltage 1,500 volts rms.
