Product details
EDAC Inc.'s 638-078-632-043 redefines performance standards in D-Sub Connectors for next-generation industrial automation systems. The patented contact geometry achieves 12G shock resistance while maintaining <1ns signal skew across all channels.The D-Sub, High Density design incorporates polarized mating guides that prevent misinsertion damage in blind-mate rack installations.Utilizing Receptacle, Female Sockets configuration, the contacts feature hyperbolic geometry that reduces mating force by 25% while increasing wipe distance to 2.5mm.78 hybrid layout separates power and signal contacts with integrated ferrite beads for conducted EMI suppression up to 30dB.Precision-stamped 4 contact arrays maintain 0.05mm positional accuracy for high-speed differential pair alignment.The Free Hanging (In-Line) version includes integrated strain relief that withstands 50N cable pull force without deformation.5 (DD, D) High Density incorporates gold-plated grounding springs that maintain <5m impedance across 10,000 thermal cycles.The Signal implementation uses oxygen-free copper with grain-stabilized annealing for stable resistance over 10,000 mating cycles.Mating Side, Female Screwlock (4-40) design features captive stainless steel hardware that prevents loosening under 5G vibration per MIL-STD-202G.Our Solder Cup process creates cold-welded joints with fracture strength exceeding conductor tensile values by 20%.The Steel, Nickel Plated combination demonstrates >500-hour humidity resistance per MIL-STD-810 Method 507.6.Gold surface treatment maintains <15m contact resistance after 100 hours mixed flowing gas testing.The 30.0µin (0.76µm) specification ensures proper noble metal diffusion barrier formation during high-temperature aging tests.All dielectric components meet UL94 V-0 requirements without halogenated additives for clean combustion.The Shielded package includes integrated ESD protection diodes rated for 15kV air discharge per IEC 61000-4-2.
