BNC PLUG CONNECTORS
BNC-connectors are some of the most popular coaxial connectors
and were created back at the end of the forties. The name BNC stands for “Bayonet
- Neill Concelman“, the inventor of the bayonet closure.
BNC-connectors are available
with an impedance of 50 Ohm and 75 Ohm, whereas the 50 Ohm connector operates at
a frequency above 4 GHz, the 75 Ohm connector at a frequency lower than 1 GHz. BNC-connectors
are mostly used in broadcasting, video, medical, and computer technologies.
BNC-connectors
are not quite as easy to use as one might imagine. The first problem is that the
BNC-connector and the RG/VIDEO-cable do not comply with the same norm. And although
some manufacturers were able to agree to produce plug connectors that would, with
a 90 % certainty, fit standard types 0.6/3.7, 0.6/2.8, and 0.3/1.8, even tiny differences
in the diameter of the jacket material or the design of the strain relief on the
plug will cause total chaos. Even slight rattling may cause the image to be distorted
and the cable will jump out of the plug if it is pulled even slightly.
But the manufacturers
are not to be blamed for this, because import cables from the USA and Asian countries
make sure that cables keep turning up for which - at least in Europa - no suitable
plugs can be found.
And if you at last find the right plug, the right cable...do
you have the right pliers at hand?
Without crimping pliers, but you can manufacture
the compression version with a soldering gun - ideal for outside installation (watertight
in compliance with IP67).
A special service by SOMMER CABLE:
Observe the technical
data for our articles, because there you will find the information about suitable
components! We offer a tool set to ensure that you are well equipped, including all
the necessary pliers, all for a reasonable price.
What does the designation 0.6/3.7
mean?
It sound complicated, but it is very easy to understand.
The number “3.7“ is
the diameter of the wire insulation on the cable. The larger the diameter, the longer
the transmission distance without greater losses.
The “0.6“ is the diameter of the
copper wire. But be careful! Diameter is not the same as wire diameter! If you work
with a flexible cable you have to make sure that the diameter of the individual copper
litz matches diameter “0.6 mm“!
(Formula: Ø = √ ((4 × diameter): π)
Unfortunately
the outer cable diameter has never been standardized in Europe!
So, now what?
The
solution to the plug problem?
There is only one thing to do: Testing, testing, testing.
And to do this we will be glad to supply a small number of cable samples free of
charge. Once you have found the cable suitable for the connector, you will have it
a lot easier in the future.
