PCN21B-110PB-2PF-G

The PCN21B-110PB-2PF-G by Hirose Electric Co Ltd 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 B 22 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 154 (110 + 44 Ground) 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 + 2 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 31.5µin (0.80µm) palladium-nickel deposition, the contacts achieve 75% better wear resistance than standard marine connectors. This coating is optimized for mating in particulate-laden seawater.
