4mm Standard Banana Cables

The 4mm standard banana plug is one of the oldest electronic connectors still in popular use today for low-voltage applications. The male 4mm connector has a hollow barrell (4mm x 14mm L) with lengthwise springs that bulge out slightly. These springs compress when the male banana plug is inserted into the female banana socket (aka banana jack) and help hold the two connectors together regardless of device orientation.

Beginning in the 1970's, manufacturers of test equipment started using shrouded banana connectors in order to prevent accidental shock through contact with the exposed metal tip of the standard banana plug. It is for this reason that standard banana cables are not IEC 61010 rated (IEC 61010 is the Advisory Standard for test equipment safety). Most 4mm standard patch cords are rated by the manufacturer for 33 Vrms / 70VDC (hand-held) and 1,200 Vrms when used hands-free.

Nevertheless, standard banana plug patch cords remain popular for many applications due to their low cost and are compatible with either standard or shrouded (safety) banana jacks.

Standard banana cables are also available with stacking 4mm banana plugs. A stacking banana connector has a standard banana jack mounted directly behind the banana plug in the same connector housing. This allows many cables to connect to a single test point.

4mm standard patch cords are availble in current ratings up to 36A with either PVC or Silicone insulated, stranded, test lead wire. Test lead wire composed of the finest strands (and highest strand count) will not only be the most flexible, it will also be the most reliable - capable of withstanding the highest number of flex cycles. PVC test lead wire is the most popular choice for clean indoor environments when wire flexibility is not important. Silicone is considered the best jacket material for test leads. It combines the desirable features of high flexibility, even at sub-zero temperatures, along with a resistance to burns and chemicals but at a higher cost.

TestPath carries over 1,000 different 4mm standard banana cables with standard, stacking or right-angle connectors in 10 colors, 6 standard lengths, 5 current capacities with either PVC, PVC coiled or silicone wire.
