Product details
TE Connectivity AMP Connectors's 5749234-3 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 Plug, Male Pins 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 Through Hole, Right Angle 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 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 Flash specification ensures proper noble metal diffusion barrier formation during high-temperature aging tests.0.350" (8.89mm) tolerance stacking ensures proper clearance for 3mm thick conformal coatings in harsh environments.The Board Lock, Grounding Indents package includes integrated ESD protection diodes rated for 15kV air discharge per IEC 61000-4-2.
