4 x Copper Beryllium 4mm Banana Connectors (No Insulator)

Made from flexible but highly conductive gold plated beryllium copper, these extremely low mass plugs are a great connector suitable for use into both 4mm sockets and also BFA/Camcon sockets. The springy nature of the metal means they always make a nice tight fit for the best contact. 

These plugs are supplied as pictured, with no insulator, they can be covered with heatshrink (not supplied) or used as they are. They are a solder only type connector, the wire can be fed in through the rear of the plug but normally it is soldered to the 'ear' that protrudes from the side, and this has the added benefit that you can stack connectors inside one another for bi-wiring (etc). Please note that due to the extremely low mass design we do not recommend using them with thick, heavy or inflexible cables, they are best suited to simple single core or thin multi strand speaker cables.
