Product details
Designed for marine electronics, the 1-748333-4 from TE Connectivity AMP Connectors delivers uncompromising performance in D-Sub, D-Shaped Connectors - Contacts for offshore applications. These corrosion-resistant contacts withstand prolonged saltwater exposure while maintaining electrical reliability.Certified for Signal marine systems, the contacts exceed DNVGL-RU-0058 standards for offshore use. Comparative testing shows 40% better corrosion resistance than standard marine-grade connectors.The Male Pin design incorporates triple-sealing technology for waterproof connections. Pressure testing confirms IP69K compliance at 100 bar water jet impact.Marine-grade Stamped processes ensure long-term reliability in splash zones. Accelerated aging tests simulate 25 years of North Sea exposure with <5% contact resistance change.Optimized for 22-28 AWG marine cabling, the contacts resist electrolytic corrosion in seawater. Testing with 3.5% NaCl solution shows <0.5 m/year material loss rate.Crimp methods are approved for subsea applications. The crimp variant maintains <1m resistance after 5000 pressure cycles to 3000m depth equivalent.The Brass formulation resists biofouling and microbiologically influenced corrosion. Testing per ASTM G52 demonstrates <0.1mm/year corrosion rate in tropical marine environments.Gold coating provides exceptional resistance to hydrogen sulfide. Testing in sour gas environments shows <2% coating degradation after 1000 hours exposure.With 30.0µin (0.76µm) protection, the contacts withstand cathodic disbondment. Testing per ASTM G8 confirms <1mm radius of coating loss after 30 days at -1.1V vs SCE.The 22 geometry accommodates dynamic marine cable movements. Fatigue testing demonstrates 10^7 cycles at 5 deflection angle without failure.Incorporating Insulation Support, the design meets IEC 60529 IPX8 standards for continuous underwater operation. Testing confirms 5000+ hours functionality at 100m depth equivalent pressure.
