QMS-078-01-L-D-RA-PC4

Samtec Inc.'s QMS-078-01-L-D-RA-PC4 delivers military-grade reliability for Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) applications in aerospace and defense systems. This MIL-DTL-83513 compliant connector withstands extreme environmental conditions while maintaining signal integrity in mission-critical applications.The Header, Outer Shroud Contacts configuration meets stringent MIL-STD-901D shock requirements for naval applications. The hermetic sealing technology prevents moisture ingress in submerged conditions.With 164 (156 + 8 Power) contact options, the connector supports complex avionics architectures. The redundant power contacts are designed for fault-tolerant systems in aircraft applications.The vibration-resistant 0.025" (0.64mm) spacing maintains contact alignment during high-G maneuvers. The design has been qualified for 500+ hours of salt fog exposure per MIL-STD-810G.The 2 row configuration provides optimal EMI shielding for sensitive radar systems. This layout has been optimized for impedance control in RF applications up to 6GHz.Engineered for Surface Mount, Right Angle; Through Hole installation in military electronics, the connector features anti-vibration locking mechanisms. The mounting system survives 15G random vibration per MIL-STD-167.Critical Ground Bus (Plane), Power Pins (8) include EMP hardening and radiation-resistant materials. These enhancements ensure operation in nuclear electromagnetic pulse scenarios.The Gold formulation prevents fretting corrosion in high-vibration environments. Testing shows 10x better performance than standard finishes in sand/dust exposure tests.With 10.0µin (0.25µm) protection, the contacts maintain performance after 1,000 thermal shock cycles (-65 C to +150 C). This specification exceeds MIL-DTL-55302 requirements.The 0.320" (8.12mm) profile has been optimized for conformal coating compatibility in military PCBAs. This height allows for proper coating coverage in harsh environments.
