Product details
Optimized for automotive Ethernet applications, EDAC Inc.'s 637-M44-330-BN4 D-Sub Connectors delivers Category 5e performance in compact form factors. The innovative shielding design reduces EMI emissions by 18dB while supporting 1Gbps data rates.The D-Sub, High Density profile incorporates chamfered edges for tool-less mating in space-constrained vehicle harness assemblies.Plug, Male Pins contacts feature dual-fork geometry that maintains <50m resistance after 25,000 vibration cycles per USCAR-2.The 44 layout separates power and signal contacts with integrated transient voltage suppressors rated for 40A surge.Precision-molded 3 dielectric bodies maintain impedance within 5 of nominal 100 differential pairs.Through Hole configuration includes integrated PCB stiffeners that reduce flex-induced solder joint stress by 70%.The 3 (DB, B) High Density design features 12-point grounding contacts that maintain <10nH inductance up to 6GHz.Signal implementation uses nanocrystalline alloys that exhibit <3% resistance change from -40 C to +125 C.The Housing/Shell (4-40) system incorporates conductive elastomer gaskets that maintain shielding integrity during 2mm panel misalignment.Our Solder methodology creates intermetallic bonds that survive 1000 thermal cycles from -55 C to +125 C.Steel, Nickel Plated provides >1000-hour corrosion resistance in GM9540P cyclic corrosion testing.The Gold surface treatment demonstrates <5% wear after 25,000 mating cycles per EIA-364-09.Precision-controlled 15.0µin (0.38µm) ensures proper noble metal diffusion barrier formation during extended thermal aging.All materials exceed UL94 V-0 requirements without red phosphorus additives for cleaner combustion.The 5A per Contact design incorporates current-sharing parallel paths that reduce thermal hot spots by 40%.Grounding Indents, Shielded include integrated magnetics for 100Base-T1 applications with <1.5dB insertion loss at 100MHz.
