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.

Description
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.
Applications
• Computers/LANs
• Test and Measurement
• Medical Equipment
• Telecommunications
• Wireless/Networks
