Product details
The MM70-314-310B2-2-R500 by JAE Electronics 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 MXM 3.0 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.The 314 contact arrangement supports automotive Ethernet. Impedance-controlled differential pairs maintain 100 10% across all mating conditions.Compatible with 0.047" (1.20mm) 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 0.020" (0.50mm) 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 Board Guide, Latches package includes active alignment aids. Integrated guide pins facilitate blind mating during vehicle assembly line installation.The Surface Mount, Right Angle 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 11.8µin (0.30µm) gold plating, the contacts achieve <10m initial resistance. This low resistance minimizes power loss in 48V mild hybrid systems.The Black housing incorporates UV stabilizers for outdoor exposure. Colorfast testing shows E<1 after 1,000 hours Xenon arc exposure.Rated for -40°C ~ 85°C, the connector uses automotive-grade materials. The housing maintains mechanical integrity from -40 C cold starts to 125 C under-hood temperatures.
