8-1579008-4 is a crimping terminal manufactured by TE Connectivity for solderless wire connection in electrical assembly applications. The terminal is designed to be crimped onto stripped wire using a crimping tool, forming a homogeneous metal connection without requiring solder, heat, or flux. The product must meet industry certification standards including vibration testing (16 hours of intense vibration exposure without electrical discontinuity or physical damage), crimp tensile strength testing to ensure wire does not pull out or separate from the crimp, and dielectric strength testing to verify insulation effectiveness. Proper crimp quality requires correct selection of wire, terminal, and applicator tool from the same manufacturer, with specifications including conductor crimp height (CH1), insulation crimp height (CH2), conductor crimp width (CR1), and insulation crimp width (CR2). This terminal is commonly used in industrial systems and electrical assemblies where reliable, cost-effective connections are required.
