4-640428-6

The 4-640428-6 by TE Connectivity AMP Connectors delivers exceptional performance in Rectangular Connectors - Free Hanging, Panel Mount for marine and offshore applications. This corrosion-resistant interconnect system exceeds DNV-GL, ABS, and Lloyd's Register standards, providing reliable connectivity in the harshest saltwater environments.As a Receptacle solution, it features a triple-sealing design that maintains IP69K protection after 500 mating cycles. The stainless steel housing resists pitting corrosion in seawater splash zones.The Female Socket design utilizes marine-grade materials that withstand 1000-hour salt fog testing. The self-cleaning contact action removes surface contaminants during mating cycles.Available in 16 configurations, the connector supports both power distribution and shipboard communication networks. The segregated contact groups prevent galvanic corrosion between dissimilar metals.The 0.156" (3.96mm) spacing provides sufficient creepage distance for 1000V AC shipboard systems. The molded ribs between contacts prevent tracking in high-humidity conditions per IEC 60092.The 1 row arrangement positions power contacts for optimal heat dissipation. The thermal management design reduces hot-spot temperatures in enclosed marine panels.The Free Hanging (In-Line) version includes integrated cable glands meeting IEC 60092-350. The corrosion-resistant bronze hardware withstands constant saltwater exposure.The Locking Ramp mechanism provides positive locking with visual indicators. The corrosion-resistant stainless steel hardware meets ASTM F593 standards.Featuring IDC technology, the system accommodates tinned marine cables. The silver-plated termination surfaces resist sulfur-induced corrosion in bilge areas.Compatible with Discrete or Ribbon Cable marine cables, the contacts maintain stable resistance through thermal cycling. The parallel contact springs compensate for vibration-induced relaxation.Supporting 22 AWG conductors, the power contacts carry 200% of rated current for 1 minute without derating. The multi-point contact design ensures reliable power transmission.The Closed End include integrated zinc sacrificial anodes for cathodic protection. These marine-specific features extend connector life in electrolytic environments.The Tin plating exceeds 2000-hour salt spray testing per ASTM B117. The thick gold flash on mating surfaces prevents fretting corrosion in vibrating environments.With 80.0µin (2.03µm) plating, the contacts maintain less than 5m resistance after extended saltwater immersion. The nickel barrier layer prevents base metal corrosion.The Red housing incorporates UV-stabilized polymers that resist fading in direct sunlight. The high-visibility options improve safety in low-light engine room conditions.
