Product details
EDAC Inc.'s 638-078-331-053 redefines D-Sub Connectors performance in marine navigation systems. The corrosion-resistant design withstands 1000-hour salt fog testing while maintaining <2dB insertion loss at 2.4GHz for AIS and radar applications.The D-Sub, High Density configuration features captive sealing rings that maintain IP68 rating at 20-meter depth.Receptacle, Female Sockets contacts employ gold-over-nickel plating that resists galvanic corrosion in seawater environments.The 78 layout includes isolated RF and power contacts with 60dB crosstalk suppression.Precision-engineered 4 contact arrangement maintains 50 impedance within 5% in salt spray conditions.Through Hole variant incorporates non-magnetic stainless steel hardware for compass-safe installations.The 5 (DD, D) High Density design provides 70dB shielding effectiveness from 10MHz to 6GHz.Signal implementation uses beryllium-free alloys that maintain elasticity in -30 C to +85 C seawater.The Mating Side, Female Screwlock (4-40) system enables one-handed operation with positive locking feedback in wet conditions.Our Solder methodology creates waterproof joints that withstand 100 bar hydrostatic pressure.Steel, Nickel Plated demonstrates >2000-hour resistance to marine atmospheric corrosion.The Gold surface treatment maintains <10m resistance after 500 immersion cycles.Precision-controlled 15.0µin (0.38µm) ensures proper corrosion barrier in splash zones.All materials exceed UL94 V-0 requirements while maintaining low smoke toxicity.The 3A per Contact design incorporates de-rating curves for 45 C ambient seawater conditions.Shielded include integrated galvanic isolators that prevent electrolytic corrosion between dissimilar metals.
