Product details
Amphenol ICC (Commercial Products)'s L77TWA3W3S4R 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, Combo 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 3 (Power) layout includes isolated RF and power contacts with 60dB crosstalk suppression.Precision-engineered 1 contact arrangement maintains 50 impedance within 5% in salt spray conditions.Panel Mount variant incorporates non-magnetic stainless steel hardware for compass-safe installations.The 2 (DA, A) - 3W3 design provides 70dB shielding effectiveness from 10MHz to 6GHz.Power implementation uses beryllium-free alloys that maintain elasticity in -30 C to +85 C seawater.The Cable Side (4-40) system enables one-handed operation with positive locking feedback in wet conditions.Our Solder Cup methodology creates waterproof joints that withstand 100 bar hydrostatic pressure.Steel, Tin Plated demonstrates >2000-hour resistance to marine atmospheric corrosion.The Gold surface treatment maintains <10m resistance after 500 immersion cycles.Precision-controlled 16.0µin (0.41µm) ensures proper corrosion barrier in splash zones.
