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

Bayonet coupling mechanism provides quick mating and unmating.
50 and 75 ohm impedance designs allow customers to match impedance to system requirements.
50 and 75 ohm connectors are intermateable to ensure nondestructive mating.
Three grades of connectors are available for military, industrial and commercial applications.

Amphenol 50 ohm BNC connectors are miniature, lightweight units 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 crimp- crimp, 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 the catalog are Military Grade 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. Amphenol’s Commercial Grade 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 products, these connectors are ideal for use on a variety of commercial applications. Amphenol’s 50 ohm BNC connectors (where indicated) are recognized under the Component Program of Underwriter’s Laboratories, Inc. They are ideal for use with medical equipment and test instrumentation where safety cannot be compromised.

BNC 75 ohm Amphenol® 123 Amphenol Corporation Tel: 800-627-7100 www.amphenolrf.com To meet the need for higher performance, impedance matched cable interconnections, Amphenol offers a full line of 75 ohm BNC connectors. These connectors can be used in a variety of applications where true 75 ohm performance is needed to insure lower signal distortion. Features/Benefits Designed for the most popular 75 ohm cables used in broadcast and CATV applications as well as for plenum cables and others — these connectors fea- ture crimp-crimp cable affixment for quick and reli- able installation. Two distinct types of 75Ω BNCs are available. Both types mate with each other and with 50 Ω BNCs.

Type 1 is designated 75 Ω BNC-T1 and provides constant 75 Ω perfomance with low VSWR DC to 4 GHz.
Type 2 is designated 75 Ω BNC-T2 and is usable with low reflection DC to 1 GHz. For applications above 1 GHz, Type 1 is recommended.
