Product details
The 1844390 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 Bolt/Screw Clamp - Wire Entry Angled to Panel 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 0.472" (12.00mm) 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 ~ 0.236" (1.0 ~ 6.0mm) 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 Piece 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.Supporting 4-14 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 Gray coding uses photoluminescent markers visible in low-light benthic environments. The pigments remain detectable at 1000m depth where only bioluminescence provides ambient lighting.Incorporating Engagement Pin, this series implements cathodic protection compatibility. The zinc-rich coating prevents galvanic corrosion when connected to sacrificial anodes in seawater power distribution systems.
