66143-3

TE Connectivity Aerospace, Defense and Marine's 66143-3 redefines reliability in Card Edge Connectors - Contacts for aerospace and defense applications. This MIL-DTL-83513 compliant connector features hermetic sealing technology for extreme environment operation. Its lightweight design meets stringent weight reduction requirements without compromising performance.The Pin configuration incorporates redundant contact paths that meet MIL-STD-1344 vibration standards. Advanced finite element analysis has optimized the contact geometry for 50g shock resistance.Designed for 22-26 AWG aircraft wiring, the contact system maintains stable impedance characteristics up to 20,000 feet altitude. The patented anti-vibration design reduces micro-arcing potential by 60%.Utilizing Crimp technology certified to NASA-STD-8739.4, this connector ensures mission-critical reliability. The cold-weld termination process creates a metallurgical bond unaffected by thermal cycling.The Brass alloy has been specially formulated for cryogenic applications down to -65 C. Material testing confirms zero brittle fracture incidents after 1000 thermal shock cycles.With Gold plating, the contacts achieve ultra-low outgassing properties (<0.1% TML) required for space applications. The proprietary process creates a diffusion barrier that prevents intermetallic growth.The 15.0µin (0.38µm) is precisely controlled to maintain stable contact resistance in vacuum environments. X-ray fluorescence testing guarantees thickness uniformity within 2% across all contacts.
