BNC Series
Description
BNC
BNC connectors are miniature units, light in weight and feature
a quick disconnect bayonet lock coupling mechanism. One of
the most widely used connector interfaces in the industry today,
BNC connectors are available in a number of termination styles
and accommodate a variety of popular coaxial cables.
Applications
Computers/LANs
Instrumentation
Test and Measurement
Medical Equipment
Broadcast (75Ω)
Features
BNC connectors with a 50 ohm nominal impedance
are designed for use in telecommunication,
datacommunication and test and instrumentation
equipment. BNC connectors with a 75 ohm nominal
impedance are designed for broadcast, video and
other applications which require impedance matched
performance. Both 50 ohm and 75 ohm BNC connectors
are intermateable.

BNC Series
Specification
BNC 50 ohm 0-4 GHz
BNC coaxial connectors are one of the world's most popular RF connectors . They are miniature, light-weight and can
operate satisfactorily up to 11 GHz . The BNC is typically used in applications from DC to 4 GHz and yield low reflection
in this frequency range.
Cable terminations are available in crimp, clamp, solder and jacket quick twist configurations. The two-stud bayonet lock
coupling provides ease of connecting and disconnecting and is ideally suited for applications such as test equipment
where this feature is notably significant.
BNC connectors are most prevalent in computer networks, audio, data processing and telecommunications equipment
because of their size and relatively low installed cost.
