The 403670631 is a Quick Disconnect Female Terminal made of brass with tin plated finish. The 3-520132-2 Ultra-Fast series terminal comes with a blue nylon 6.6 (polyamide 6.6) fully insulated barrel. It supports flag terminal orientation and 90° terminal angle. The Tab-Lok crimp terminal accepts 16 to 14AWG stranded composition discrete wire. The one-piece fully insulated premier line FASTON receptacle crimp helps prevent shock and short hazards. The ultra-fast fully insulated terminal precludes the need for costly electrical safety interlocks or special protective shields to help prevent shock hazards. In addition, electrical short-circuits from exposed leads are eliminated, even in equipment requiring close contact spacing. It offers the advantage of a completely protected terminal and a wire crimp with comparable electromechanical.
