Top quality banana plug with robust design and sleeve with polished ruthenium finish. Offering high contact pressure due to an expanding inner spike ensures a solid mechanical fit. Termination fitted with two Torx™ screws size T6 for secure crimp connection as well as cable strain relief. Easy fit for wire size up to 10mm? / 8 AWG. Banana Plug Topline Straight banana plug with WBT Topline quality. Robust construction made from a special copper alloy. Sleeve with polished ruthenium finish. High clamping force by means of expandable centre pin. The expansion mechanism is activated by simply screwing the sleeve in the direction of the plug tip. In this way, the cross bar pushes the inner spike forwards and ensures not only a firm positioning of the plug but also a continual and high contact pressure. The clamping force and high copper content of the alloy give the WBT-0600 an especially high conductivity and precise signal transmission. The fabrication from one piece does not permit any unnecessary transition resistance. The plug body is nickel-free and 24 carat gold-plated so that any oxidation which could influence contact quality is impossible. The WBT-0600 is suitable for both the crimping connection technique and the solder technique. The wide gap between the two Torx screws should be used for soldering on your cable. WBT recommends the surface friendly silver solder WBT-0800 or rather the lead-free version, WBT-0805. For those preferring the crimping technique, the designated Torx screws (T.6) should be used to provide a durable connection of the crimped cable end, as well as reliable strain relief. If using the crimping connection with your WBT-0600 it can be used time and again since the valuable protective surface of the plug will not be damaged by soldering.
