Product details
Optimized for marine electronics, the 1970720000 from Weidmüller sets new benchmarks in Terminal Blocks - Headers, Plugs and Sockets corrosion resistance. This saltwater-rated interconnect solution combines robust mechanical design with advanced materials to withstand the harshest ocean environments. The Terminal Blocks - Headers, Plugs and Sockets delivers reliable performance in offshore oil rigs and naval systems.The Plug, Male Pins construction incorporates triple-sealing for underwater applications. Compared to standard marine connectors, it provides IP68 protection at 100m depth for 30 days continuous immersion.Available in 4 positions, the design supports both power and data transmission in marine systems. The isolated contact groups prevent galvanic corrosion between dissimilar metals.4 positions per level optimize packaging in confined marine electronics bays. The staggered arrangement prevents capillary action of seawater between contacts.The 1 stacking capability enables vertical integration in sonar arrays. The pressure-balanced design maintains performance at various ocean depths.Featuring 0.150" (3.81mm) pitch spacing, the design exceeds DNV-GL requirements for offshore equipment. The reinforced isolation prevents tracking in salt-fog conditions.With 180° entry options, the connector accommodates both deck and bulkhead installations. The 360 sealing prevents water ingress in wave-impact zones.The Screw - Clamping Yoke (Tension Sleeve) system ensures corrosion-resistant connections meeting MIL-DTL-5015 standards. The tinned copper contacts resist sulfide attack in anaerobic seabed conditions.Free Hanging (In-Line) installation satisfies ABS and Lloyd's Register requirements. The explosion-proof variants are certified for hazardous zone marine environments.Meeting 17.5A IEC standards for marine applications, the design handles engine vibration spectra. The mechanical damping reduces contact fretting in rough seas.The 320 V certification includes testing for salt spray endurance. The design exceeds 5,000 hours salt fog exposure per IEC 60068-2-52.Rated for 10 A in submerged conditions, the contacts utilize naval brass alloys. The material selection prevents dezincification in seawater.The 300 V rating includes testing for lightning strikes on masts. The insulation system withstands 10kV surge pulses without degradation.Compatible with 16-28 AWG marine-grade cables, the termination resists oil and chemical exposure. The integral potting chambers prevent wicking along conductors.The Black housing incorporates international maritime color coding. The fluorescent markers enhance visibility in low-light emergency situations.Operating across -50°C ~ 120°C range, from Arctic waters to engine room heat. Materials testing confirms 10,000 thermal cycles without seal degradation.Tin plating provides optimal performance in marine environments. The palladium-nickel coating resists pitting in polluted harbors.The Mating Flange include integrated cathodic protection terminals. These allow connection to sacrificial anodes for extended service life in seawater.
