4 x Copper Beryllium 4mm Banana Connectors

Made from flexible but highly conductive beryllium copper, these 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. They are a screw type design, with two screws to get a good connection onto the wire (please note the clear plastic tube that is shown in the pictures is there purely to stop the screws from falling out in transit).

These plugs feature a strong body which makes them much less likely to bend than most similar plugs, making them suitable for a wider range of cables than many. The wire opening is 5mm but naturally some if that is required for the screw connections, so a 3mm or less wire diameter is probably ideal. The quality rubber finished outer jackets can cover up to approximately 8mm of insulation diameter. This listing is for a set of 4 as pictured, two red and two black.
