Product details
The 345-138-500-878 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 - Dual 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 69 contacts per row, the design optimizes signal routing. Alternate ground contacts provide return paths every 0.100" for EMI control.The 138 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 2 row configuration includes power contacts. These 3A-rated contacts feature 50% larger cross-section for reduced voltage drop.The 0.100" (2.54mm) pitch design enables miniaturization without compromising reliability. Micro-machined contacts maintain precise alignment despite thermal cycling.Dual readout capability supports automotive diagnostic systems. Dedicated sense contacts provide real-time connection integrity monitoring.The Card Guides package includes active alignment aids. Integrated guide pins facilitate blind mating during vehicle assembly line installation.The Through Hole version includes IP6K9K sealing. Overmolded gaskets prevent water ingress during high-pressure vehicle washes.Solder Eyelet(s) 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.
