MX 4mm Banana Male Plug Connector Gold Plated Heavy Duty For 6mm Cable (MX-2896)

Most banana plugs are sized for thin, flexible test lead wire, but a lead built to carry real current - a bench supply output, a battery test rig - benefits from a thicker 6mm cable that this plug is specifically sized to accept and clamp securely around. The gold plating on the contact resists the oxidation that would otherwise raise contact resistance over years of use, and the metal cap gives the whole connector a sturdier feel than a lightweight economy plug. The heavy-duty build and larger cable acceptance make this the plug to reach for when a test lead is genuinely going to see higher current rather than light signal-level use.
