QR/P-4S-C(01)

Hirose Electric Co Ltd's QR/P-4S-C(01) sets the benchmark for Backplane Connectors - Housings in military-grade avionics systems. This rugged interconnect solution exceeds MIL-STD-38999 performance requirements while addressing the unique challenges of next-generation flight control and navigation equipment.The Housing for Female Sockets architecture features triple-start threads that enable rapid mating/de-mating cycles (<5 seconds) critical for field maintenance of airborne radar systems.Utilizing Rack and Panel technology, this connector achieves 360 continuous shielding with <1nH inductance for sensitive RF front-end modules in electronic warfare systems.With 4 configurable positions, this solution supports mixed-signal requirements in fly-by-wire flight control computers and heads-up displays.The 0.177" (4.50mm) military-standard pitch maintains impedance control across extended temperature ranges (-55 C to +200 C) for turbine engine monitoring systems.The 2 concentric row design provides balanced RF grounding paths for phased array antenna elements in satellite communication terminals.The Panel Mount interface incorporates anti-vibration features that maintain contact integrity under 20G random vibration profiles specified for fighter jet avionics.As Receptacle, this component meets MIL-PRF-55302 requirements for salt spray and fungus resistance in naval aviation applications.The Mating Guide package includes hermetic glass seals that maintain 10^-9 atm-cc/sec helium leak rates in space-qualified payload interfaces.The Blue housing material provides radar-absorbent properties while meeting flame propagation requirements for aircraft cabin installations.
