Product details
The 1757820-3 by TE Connectivity Aerospace, Defense and Marine redefines D-Sub, D-Shaped Connectors - Housings technology for marine navigation systems, crafted to withstand harsh saltwater environments. This corrosion-resistant D-Sub connector delivers uncompromised signal transmission while meeting stringent DNV-GL marine certification requirements.Featuring D-Sub design, the connector achieves 45% better vibration resistance than standard models through patented interlocking shell architecture.The Receptacle for Female Contacts configuration utilizes triple-sealed contacts that maintain IP68 rating at 20m depth for 30 days, critical for underwater ROV applications.With 25 available circuits, the design supports simultaneous power over Ethernet (PoE++) and high-speed data transmission up to 10Gbps.Precision-engineered 2 row arrangement prevents salt creepage between contacts, exceeding IEC 60529 salt mist corrosion standards.The 3 (DB, B) incorporates sacrificial zinc anodes that provide 15-year corrosion protection in seawater environments.Special Signal contacts feature hydrophobic nano-coating that repels moisture while maintaining <5m contact resistance after 5000 mating cycles.Optimized for Free Hanging (In-Line) installation, the connector includes anti-rotation locking tabs that withstand 50Nm of torque without deformation.The Housing/Shell (Unthreaded) design integrates conductive silicone seals that maintain EMI shielding effectiveness >90dB even after prolonged UV exposure.Constructed with Steel, Yellow Chromate Plated Zinc, the housing demonstrates exceptional resistance to biofouling and marine growth accumulation.Precision 20µin (0.51µm) plating ensures stable impedance characteristics ( 1.5 ) in fluctuating temperature and humidity conditions.
