Constructed from tin-plated brass with a nylon housing rated UL 94 V-2 flammability, the terminal includes a funnel wire entry, wire stop, and visual inspection features for crimp quality verification. The receptacle is UL listed (File No. E-66717) and CSA certified, meeting IEC 380, 601, and 950 standards for secondary insulation fixing. Common applications include automotive wiring harnesses, appliance interconnects, and industrial control systems where reliable, insulated quick-disconnect connections are required.
