8-1377173-4

Designed for automotive electronics, the 8-1377173-4 by TE Connectivity AMP Connectors sets new standards in Terminals - Spade Connectors reliability. This vibration-resistant connector system meets ISO 16750-3 specifications while providing exceptional electrical performance in engine compartment environments. Its robust construction addresses the unique challenges of next-generation vehicle architectures.The Standard configuration in this automotive-grade connector provides positive locking that exceeds USCAR-2 requirements. This design prevents accidental disconnection in high-vibration environments.Featuring M2.5 Stud compatibility, this terminal supports both conventional and high-voltage vehicle systems. The dual-material construction prevents galvanic corrosion in mixed-metal applications.Precisely engineered to 0.217" (5.50mm) dimensions, this connector maintains proper creepage distances for 48V systems. The chamfered edges facilitate blind mating during assembly.The 0.772" (19.61mm) profile incorporates advanced strain relief that reduces conductor fatigue by 70% in dynamic applications. This feature is critical for door harness and suspension wiring.Developed for Free Hanging (In-Line) installations, this terminal simplifies assembly in confined vehicle spaces. The orientation-specific design prevents incorrect routing during manufacturing.Utilizing Crimp technology, this connector achieves gas-tight joints that resist thermal cycling. The process is compatible with both manual and automated production lines.Engineered for 16-22 AWG conductors, this terminal maintains stable contact resistance from -40 C to 125 C. The dual-spring design compensates for material expansion differences.The Insulated material exceeds LV214 flame resistance requirements without compromising flexibility. Special formulations resist automotive fluids including brake fluid and transmission oil.The Red coding follows OEM-specific standards for quick identification during servicing. This visual system reduces diagnostic time in complex vehicle architectures.Tin plating technology provides exceptional corrosion resistance in salty environments. Testing shows less than 5% contact resistance change after 1000 hours of salt spray.The Copper formulation in this automotive connector offers optimal spring characteristics for vibration resistance. Advanced metallurgy ensures stable performance over 15-year vehicle lifecycles.
