Product details
The L177HRDG78S from Amphenol ICC (Commercial Products) represents the pinnacle of D-Sub, D-Shaped Connectors - Housings technology, engineered for mission-critical connectivity solutions. This high-density D-Sub connector delivers exceptional signal integrity while maintaining robust EMI shielding characteristics, making it ideal for aerospace and defense applications where reliability is paramount.Designed with D-Sub, High Density configuration, this connector ensures optimal space utilization without compromising mating cycle durability, achieving over 500 mating cycles in rigorous testing.Featuring Receptacle for Female Contacts architecture, the contact arrangement provides superior current carrying capacity (up to 5A per contact) while minimizing insertion loss below 0.5dB at 3GHz frequencies.With 78 available positions, engineers can implement complex multi-protocol interfaces while maintaining backward compatibility with legacy systems through intelligent pin mapping.The 4 row arrangement has been thermally optimized to prevent current crowding effects, reducing thermal resistance by 30% compared to conventional designs.Precision-machined 5 (DD, D) High Density shell geometry incorporates advanced strain relief features that increase cable retention force by 2.5x under vibration conditions.Specialized Signal contacts employ gold-over-nickel plating (50 in min) to ensure stable contact resistance (<10m ) even after prolonged environmental exposure.The Free Hanging (In-Line) installation method incorporates anti-rotation safeguards that maintain connector alignment within 0.25mm during high-G shock events.Innovative Board Side (M3) design integrates conductive gaskets that achieve 360 shielding effectiveness of 90dB at 1GHz, exceeding MIL-DTL-24308 requirements.Constructed with Steel, Tin Plated materials, the housing demonstrates exceptional corrosion resistance (500hrs salt spray per ASTM B117) while maintaining <0.5 V electromagnetic leakage.Precisely controlled 100µin (2.54µm) plating thickness guarantees consistent impedance characteristics ( 2% variation) across the entire connector interface.
