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.
