4-1377173-1

TE Connectivity AMP Connectors's 4-1377173-1 sets new benchmarks in Terminals - Wire Pin Connectors performance, specifically developed for mission-critical automotive electronics. The patented contact geometry ensures <1m resistance while withstanding engine compartment temperatures up to 150 C. These terminals are IATF 16949 certified for use in safety-related vehicle systems.Precision-machined pin diameters of Circular - 0.071" (1.80mm) Dia provide optimal current density for 48V mild hybrid systems. The rectangular variants feature anti-rotation design that prevents terminal twisting during harness assembly.The 0.264" (6.71mm) pin length is calculated to achieve optimal thermal dissipation in high-current applications. This prevents localized heating that could degrade insulation materials in electric vehicle battery management systems.Designed for space-constrained installations, the 0.815" (20.70mm) overall length includes integrated locking tabs that secure the connector in ECU housings without requiring additional fasteners.Supporting 16-22 AWG (0.2~1.6mm²) wiring, these terminals utilize dual-crimp technology that meets LV214-2 automotive standards. The optimized crimp profile prevents wire strand breakage during harness flexing.The 0.142" (3.61mm) range accommodates both cross-linked polyethylene and silicone-insulated cables commonly used in automotive wire harnesses. The flared entry design prevents insulation damage during automated insertion.Insulated options include color-coded heat shrink that withstands underhood fluids like transmission oil and brake fluid, as identified in SAE J2030 testing protocols.The Crimp process creates metallurgical bonds that exceed USCAR-25 vibration requirements. Piercing variants eliminate the need for wire stripping in CAN bus network installations.Key Serrated Termination include laser-marked position indicators that survive steam cleaning, crucial for agricultural equipment connectors exposed to frequent washdowns.Red identification follows OEM-specific coding schemes for quick fault tracing in complex vehicle wiring systems. Fluorescent variants enhance visibility in low-light service conditions.
