4-1377173-2

The 4-1377173-2 by TE Connectivity AMP Connectors revolutionizes Terminals - Wire Pin Connectors for marine propulsion systems. These seawater-resistant connectors meet DNVGL-RU-SHIP Pt.4 Ch.8 standards with triple-layer corrosion protection. The pressure-balanced design maintains performance at 5000m depth while withstanding 15kV lightning strikes per IEC 62305-1.The Circular - 0.071" (1.80mm) Dia contacts utilize nickel-aluminum bronze alloy that provides 50-year service life in seawater environments. The tapered pin design ensures positive engagement even with marine growth present on ROV connections.With 0.390" (9.91mm) pin length, these terminals achieve proper wipe action in dynamic umbilical cables. The extended contact area maintains <10m resistance despite constant flexing in wave energy converters.The 0.937" (23.80mm) design includes integrated cathodic protection zones that prevent galvanic corrosion in mixed-metal offshore installations. The buoyant variants reduce cable loading in floating wind turbine arrays.Rated for 16-22 AWG (0.2~1.6mm²) marine-grade cables, these terminals feature tinned copper construction that resists sulfide attack in deep-sea mining operations. The crimp indentations are optimized for copper-nickel alloy conductors.The 0.142" (3.61mm) accommodates both oil-filled and dry-mate subsea cables. The syntactic foam insulation provides neutral buoyancy while withstanding 300bar hydrostatic pressure.Insulated options include HSNO-compliant materials that prevent marine organism attachment without toxic leaching in sensitive reef environments.The Crimp process creates hyperbaric-chamber-tested connections that maintain IP68 sealing at 7000m depth. The field-matable variants enable repairs without drydock access.Advanced Serrated Termination include integrated fiber optic multiplexing that transmits power, data, and video through single hybrid cables in underwater observatory networks.Red coding follows IMO resolution A.760(18) for shipboard safety systems. The photoluminescent variants guide emergency disconnection in blackout conditions.
