1703690

The 1703690 from Phoenix Contact pioneers Terminal Blocks - Panel Mount technology for undersea applications. Engineered to withstand 11,000-meter depths, these terminal blocks maintain reliable performance in ROVs, seafloor observatories, and submarine communication systems.The Header, Female Sockets system utilizes corrosion-resistant Hastelloy C-276 contacts that withstand seawater exposure for 25+ years. This durability has been proven in WHOI's Alvin submersible electrical systems during 5000+ deep ocean dives.Designed for pressure compensation, the Bolt/Screw Clamp - Wire Entry 90° to Panel options feature oil-filled chambers that equalize to ambient pressure at 1100bar. This design prevents implosion risks in hadal zone scientific instruments.Available in 1.750" (44.45mm) configurations, these terminals enable compact packaging in autonomous underwater vehicles. The 6mm titanium variant reduces buoyancy while maintaining 10kPSI crush resistance for Mariana Trench exploration.Compatible with 0.039 ~ 0.118" (1.0 ~ 3.0mm) specifications from 3mm to 50mm, the mounts adapt to both lightweight polymer housings and thick titanium pressure vessels. The tapered seal design maintains integrity during thermal cycling from surface to abyssal temperatures.The 2 matrix supports distributed sensor networks in oceanographic moorings. The daisy-chain capable design simplifies deployment of 100+ node tsunami warning systems across oceanic plates.The 2 Piece, Snap Lock incorporates syntactic foam flotation that prevents sinking if housings breach. This safety feature meets IMCA guidelines for ROV tether management systems in offshore oil operations.Precision 0.400" (10.16mm) spacing prevents dendritic growth in seawater-filled enclosures. The alumina ceramic insulation maintains >10G resistance after 10,000 pressure cycles in deep-sea camera housings.Rated for 600 V operation, the terminals withstand 5kV pulses from underwater sparker arrays. This ruggedness is essential for marine seismic exploration equipment operating in conductive seawater.The 55 A capacity handles 500A fault currents in submarine power cables. The silver-graphite contacts prevent welding during short-circuit events in offshore wind farm umbilical connections.Supporting 6-20 AWG ranges, these terminals accommodate both microcoax for sonar signals and heavy conductors for ROV thrusters. The pressure-balanced oil compensation prevents dielectric fluid migration in penetrator assemblies.The Green coding uses photoluminescent markers visible in low-light benthic environments. The pigments remain detectable at 1000m depth where only bioluminescence provides ambient lighting.The 1 single-plane construction minimizes volume for pressure housings. This design allows 30% smaller diameter for Nereus-class hybrid ROV electronics cans rated to full ocean depth.
