DF64-3S-4.5H(21)

Hirose Electric Co Ltd's DF64-3S-4.5H(21) sets new benchmarks in Solid State Lighting Connectors performance, specifically developed for automotive electrification systems. This ruggedized solution combines EMI shielding with waterproof construction, addressing the stringent requirements of next-generation vehicle architectures.With its Board to Board or Cable architecture, the connector supports both power delivery and high-speed data networks in unified packaging. The hybrid design eliminates separate wiring runs, reducing vehicle weight by up to 15% in harness-intensive applications.The Receptacle, Non-Gendered interface incorporates IP67-rated sealing when mated, protecting sensitive electronics from fluid ingress. Dual-contact wiping action ensures reliable connectivity despite road-induced vibrations.Scalable from 3 positions, the modular system grows with evolving E/E architectures. Position-specific keying prevents misalignment during harness assembly in low-light service conditions.Engineered for Surface Mount, Right Angle installation, the connector withstands G-force loads encountered in collision scenarios. The breakaway design protects wiring integrity during impact events.The Solder method has been validated for 85 C continuous operation in engine compartments. Self-fluxing alloys create reliable joints without additional processing steps.The 0.177" (4.50mm) dimension accommodates 2.5mm power conductors alongside 0.35mm signal wires in unified cavities. Staggered contact arrangement minimizes crosstalk between adjacent circuits.The Latch Holder mechanism provides positive engagement feedback audible over factory ambient noise. The dual-stage locking system prevents partial mating conditions.Solder Retention include integrated diagnostic LEDs and service disconnection points. The service-friendly design enables module replacement without specialized tools.Beige pigmentation meets automotive OEM color-coding standards while resisting chemical degradation from underhood fluids. High-visibility tones facilitate assembly line error-proofing.Copper Alloy formulation resists sulfurization from exhaust gases, maintaining <10m contact resistance throughout the vehicle lifecycle. The alloy's thermal expansion properties match surrounding materials to prevent stress fractures.Tin plating exceeds automotive corrosion test requirements, including 1000+ hours of salt spray exposure. The noble metal surface prevents galvanic corrosion in mixed-metal systems.The Liquid Crystal Polymer (LCP) compound achieves UL 746C F1 outdoor weathering ratings without UV-protective coatings. Material selection avoids halogenated compounds for environmental compliance.Performance-certified for -55°C ~ 105°C environments, the connector survives thermal shock from winter cold starts to desert heat soaking. All materials maintain mechanical properties at temperature extremes.
