QR/P4-40P-C(21)

Hirose Electric Co Ltd's QR/P4-40P-C(21) 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 Male Pins 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 40 configurable positions, this solution supports mixed-signal requirements in fly-by-wire flight control computers and heads-up displays.The 0.100" (2.54mm) 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 Plug, this component meets MIL-PRF-55302 requirements for salt spray and fungus resistance in naval aviation applications.The Guide Pin package includes hermetic glass seals that maintain 10^-9 atm-cc/sec helium leak rates in space-qualified payload interfaces.The Black housing material provides radar-absorbent properties while meeting flame propagation requirements for aircraft cabin installations.
