Product details
Designed for precision interconnect solutions, Aces Connectors's 91781-31408-001 Card Edge Connectors - Edgeboard Connectors delivers unmatched reliability in high-vibration environments. Developed for aerospace and defense applications, this connector meets rigorous MIL-SPEC performance requirements.The MXM 3.0 compatible design features guided card entry. Angulated lead-ins prevent card edge damage during blind mating operations.Female configuration incorporates positive latching mechanism. The over-center latch design requires 25N minimum release force to prevent accidental unmating.The 314 contact arrangement supports redundant power distribution. Parallel power contacts reduce current density by 40% compared to single-contact designs.Accommodating 0.047" (1.20mm) cards, the connector features dual-beam contacts. This balanced force design prevents card deformation during insertion.The 2 row configuration includes integrated ground planes. These continuous reference surfaces maintain signal return paths for controlled impedance.0.020" (0.50mm) pitch design enables 56Gbps PAM4 signaling. The air dielectric between contacts minimizes dielectric loss at millimeter-wave frequencies.Dual readout capability supports hot-swap applications. Staggered contact lengths provide make-first/break-last sequencing for safe board insertion.Board Guide, Solder Retention include hermetic sealing options. Viton gaskets provide moisture resistance per MIL-STD-202 Method 106.The Surface Mount, Right Angle version includes conductive backshell. This Faraday cage design provides 360 EMI shielding effectiveness >60dB at 10GHz.Solder process creates void-free solder joints. Automated optical inspection (AOI) verifies complete fillet formation on all terminations.The Copper Alloy contacts exhibit excellent thermal conductivity. This property helps dissipate heat generated by contact resistance.Gold plating provides durable wear surface. Micro-hardness testing shows Knoop hardness >200HK for extended mating cycle life.With 3.00µin (0.076µm) gold plating, the contacts achieve <2m contact resistance. This low resistance minimizes voltage drop in power distribution applications.Black housing incorporates radiopaque markers. These features enable X-ray inspection of fully assembled systems.Rated for -55°C ~ 85°C, the connector uses cryogenic-grade materials. Glass transition temperature exceeds maximum operating temperature by 50 C margin.
