5646731-1

The 5646731-1 by TE Connectivity AMP Connectors pioneers advanced solutions in Backplane Connectors - Hard Metric, Standard for underwater robotics. Designed for deep-sea exploration systems, this connector series withstands extreme pressures while maintaining reliable signal transmission. Its innovative sealing technology and corrosion-resistant materials meet the challenges of submersible vehicles and oceanographic sensors.Featuring Header, Male Pins configuration, this pressure-balanced connector maintains performance at 6000m depth. The oil-filled design compensates for hydrostatic pressure without signal degradation.The AB 25 form factor incorporates titanium housing that resists seawater corrosion. Testing shows less than 0.1% weight loss after 5-year saltwater immersion per ASTM B117.With 125 isolated channels, this solution supports complex sensor arrays. The optimized layout provides 1000V isolation between circuits in conductive seawater environments.The All configuration enables power-over-fiber transmission alongside electrical signals. Hybrid contacts handle both 10kW power and 100Gbps optical data streams.The 0.079" (2.00mm) spacing achieves pressure-resistant density while maintaining 5mm creepage distance. The glass-filled PEEK material withstands 10,000 pressure cycles at 600bar.The 5 contact arrangement provides balanced pressure loading. This symmetrical design prevents housing deformation during deep-sea pressure fluctuations.Designed for Through Hole installation on submersibles, this connector features hydrostatic pressure relief. The automatic equalization system prevents vacuum formation during ascent.The Press-Fit process creates hermetic seals that pass 500-hour hyperbaric testing. The glass-to-metal feedthroughs maintain insulation resistance above 1G at full ocean depth.Specifically engineered for Backplane in ROV systems, this series meets DNVGL-RU-NAVAL certification requirements. The cathodic protection compatibility prevents galvanic corrosion.The Gold plating provides exceptional performance in hydrogen sulfide-rich environments. Testing shows contact resistance stability after 1000 hours in anoxic seawater.With 30.0µin (0.76µm) palladium-nickel deposition, the contacts achieve 75% better wear resistance than standard marine connectors. This coating is optimized for mating in particulate-laden seawater.
