QMS-026-06.75-H-D-PC8

Designed for automotive electronics, the QMS-026-06.75-H-D-PC8 by Samtec Inc. sets new standards for Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) in vehicle applications. This AEC-Q200 qualified connector delivers unmatched reliability for ADAS systems and in-vehicle networks, featuring enhanced vibration resistance and temperature cycling performance.The automotive-grade Header, Outer Shroud Contacts configuration incorporates redundant contact points that meet LV214 requirements. This failsafe design ensures continuous operation even under extreme vibration conditions.With 68 (52 + 16 Power) available configurations, the connector supports evolving automotive architectures. The optimized layout minimizes electromagnetic emissions for CAN FD and Ethernet applications.The 0.025" (0.64mm) spacing has been validated for automotive shock and vibration standards. Micro-locking features prevent contact walking during thermal expansion cycles.The 2 row design provides balanced current distribution for 48V mild hybrid systems. This configuration has been tested for 10,000 thermal cycles from -40 C to +125 C.Developed for Surface Mount, Through Hole applications, the connector features anti-corrosion coatings that resist road salt exposure. The mounting system maintains seal integrity under pressure washing conditions.Key Board Guide, Ground Bus (Plane), Power Pins (8) address automotive-specific challenges including coolant immersion resistance. The connector body materials are halogen-free and meet GMW3191 flame retardancy requirements.The Gold formulation prevents sulfide formation in exhaust-prone environments. Testing shows 5x better performance than standard finishes in sulfur dioxide exposure tests.Precisely controlled 30.0µin (0.76µm) ensures stable contact resistance over the vehicle's lifetime. This specification exceeds USCAR-2 electrical endurance requirements.The 11mm, 13mm options accommodate various ECU mounting configurations. The design prevents water wicking in under-hood applications.With 0.250" (6.35mm) clearance, the connector allows for conformal coating application in automotive PCBAs. This height has been optimized for automated optical inspection systems.
