MX 4mm Banana Crimp Type Male Plug Connector Gold Plated Beryllium Copper (MX-1403)

Crimping gives a fast, repeatable wire termination that doesn't depend on solder skill or a heated iron being available, which matters when building test leads in volume or in the field. This banana plug's crimp barrel takes a stripped wire end and compresses down to a secure mechanical and electrical connection, while the gold-plated beryllium copper contact tip resists the oxidation that degrades a bare-metal contact's performance over years of bench use. It's the plug to reach for when building custom test leads where a fast, consistent crimp termination is preferred over soldering each one individually.
