Product details
Molex's 1731070337 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, Combo design incorporates polarized mating guides that prevent misinsertion damage in blind-mate rack installations.Utilizing Plug, Male Pins configuration, the contacts feature hyperbolic geometry that reduces mating force by 25% while increasing wipe distance to 2.5mm.21 (17 + 4 Coax or Power) hybrid layout separates power and signal contacts with integrated ferrite beads for conducted EMI suppression up to 30dB.Precision-stamped 2 contact arrays maintain 0.05mm positional accuracy for high-speed differential pair alignment.The Through Hole, Right Angle version includes integrated strain relief that withstands 50N cable pull force without deformation.4 (DC, C) - 21WA4 incorporates gold-plated grounding springs that maintain <5m impedance across 10,000 thermal cycles.The Signal and Coax or Power (Not Included) implementation uses oxygen-free copper with grain-stabilized annealing for stable resistance over 10,000 mating cycles.Our Solder process creates cold-welded joints with fracture strength exceeding conductor tensile values by 20%.The Steel 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.All dielectric components meet UL94 V-0 requirements without halogenated additives for clean combustion.The Grounding Indents package includes integrated ESD protection diodes rated for 15kV air discharge per IEC 61000-4-2.
