Product details
The 346-031-521-678 by EDAC Inc. redefines performance standards in Card Edge Connectors - Edgeboard Connectors for automotive electronics. Specifically engineered for in-vehicle networks, this connector exceeds AEC-Q200 qualification requirements for harsh automotive environments.Supporting Non Specified - Single Edge applications, the connector features anti-fretting design. The multi-point contact system prevents micro-motion induced wear in vibration-prone installations.The Female configuration includes tactile engagement feedback. Audible click and 5N snap force provide positive mating confirmation in low-visibility conditions.With 31 contacts per row, the design optimizes signal routing. Alternate ground contacts provide return paths every 0.100" for EMI control.The 31 contact arrangement supports automotive Ethernet. Impedance-controlled differential pairs maintain 100 10% across all mating conditions.Compatible with 0.054" ~ 0.070" (1.37mm ~ 1.78mm) cards, the connector features tapered entry. This self-centering design compensates for 0.5mm card misalignment during assembly.The 1 row configuration includes power contacts. These 3A-rated contacts feature 50% larger cross-section for reduced voltage drop.The 0.125" (3.18mm) pitch design enables miniaturization without compromising reliability. Micro-machined contacts maintain precise alignment despite thermal cycling.Single readout capability supports automotive diagnostic systems. Dedicated sense contacts provide real-time connection integrity monitoring.The Through Hole version includes IP6K9K sealing. Overmolded gaskets prevent water ingress during high-pressure vehicle washes.Solder process is compatible with automotive soldering profiles. The thermal mass design prevents tombstoning during reflow up to 260 C peak temperature.The Copper Alloy contacts exhibit excellent stress relaxation resistance. After 1,000 hours at 150 C, contact force remains >75% of initial value.Gold plating provides superior corrosion resistance. Testing per ISO 9227 shows no degradation after 96 hours salt spray exposure.With 10.0µin (0.25µm) gold plating, the contacts achieve <10m initial resistance. This low resistance minimizes power loss in 48V mild hybrid systems.The Cantilever design includes redundant contact points. This dual-touch system maintains conductivity even if one contact point becomes contaminated.The Green housing incorporates UV stabilizers for outdoor exposure. Colorfast testing shows E<1 after 1,000 hours Xenon arc exposure.Top Mount Opening, Threaded Insert, 4-40 includes anti-rotation tabs. These positive locking features prevent connector movement during vehicle vibration.Rated for -40°C ~ 105°C, the connector uses automotive-grade materials. The housing maintains mechanical integrity from -40 C cold starts to 125 C under-hood temperatures.
