Product details
TE Connectivity Aerospace, Defense and Marine's 1757845-3 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 configuration features captive sealing rings that maintain IP68 rating at 20-meter depth.Plug, Male Pins contacts employ gold-over-nickel plating that resists galvanic corrosion in seawater environments.The 25 layout includes isolated RF and power contacts with 60dB crosstalk suppression.Precision-engineered 2 contact arrangement maintains 50 impedance within 5% in salt spray conditions.Through Hole, Right Angle variant incorporates non-magnetic stainless steel hardware for compass-safe installations.The 3 (DB, B) 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 Housing/Shell (Unthreaded) 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, Yellow Chromate Plated Zinc demonstrates >2000-hour resistance to marine atmospheric corrosion.The Gold surface treatment maintains <10m resistance after 500 immersion cycles.Precision-controlled 10.0µin (0.25µm) ensures proper corrosion barrier in splash zones.The 5A design incorporates de-rating curves for 45 C ambient seawater conditions.0.318" (8.08mm) dimensional control ensures proper drainage in vertical installations.
