1703797

Phoenix Contact's 1703797 delivers military-grade Terminal Blocks - Panel Mount performance for defense electronics. Meeting stringent MIL-DTL-38999 requirements, these terminal blocks ensure mission-critical reliability in radar systems, electronic warfare suites, and armored vehicle electronics.The Header, Female Sockets system employs self-cleaning rhodium contacts that resist corrosion in desert, marine, and Arctic environments. Field testing demonstrates 10,000 mating cycles with <5m resistance change in M1 Abrams tank electronics.Engineered for EMP protection, the Bolt/Screw Clamp - Wire Entry Parallel to Panel options feature gas-discharge tube integrated designs that clamp transients to <50V. This meets MIL-STD-461G CS115 requirements for naval radar signal processing equipment.With 3.217" (81.72mm) options available, system integrators can optimize space in ruggedized electronics bays. The 9.53mm variant enables 30% higher packing density in F-35 avionics LRUs while maintaining vibration resistance to 20G RMS.Compatible with 0.039 ~ 0.118" (1.0 ~ 3.0mm) specifications from 2mm to 25mm, the mounts adapt to both lightweight UAV avionics and armored vehicle electronics pods. The crush-resistant design survives 50G impacts in IED-protected MRAP vehicles.The 4 arrangement supports triple-redundant voting architectures in flight control systems. The symmetrical layout ensures equal path lengths for fault-tolerant avionics networks in Boeing 787 Dreamliners.The 2 Piece, Snap Lock - Front Flange incorporates conductive elastomer seals that maintain EMI shielding effectiveness >100dB up to 40GHz. This performance exceeds requirements for AESA radar front-end modules in F/A-18 Super Hornets.Precision 0.400" (10.16mm) spacing prevents tracking in high-humidity conditions. The PTFE-filled polyimide insulation resists fungus growth per MIL-STD-810 Method 508.7 while maintaining arc resistance in 400Hz aircraft power systems.Rated for 600 V operation, the terminals withstand 5kV lightning strikes per DO-160 Section 22. This protection is critical for wingtip-mounted electronics in commercial and military aircraft.The 55 A capacity handles 200% overload for 5 minutes in naval gun director systems. The silver-cadmium oxide contacts resist welding during fault conditions in shipboard power distribution networks.Supporting 6-20 AWG ranges, these terminals handle both 44AWG sensor leads and 500MCM power cables. The captive screw design prevents loosening under 15G vibration in artillery fire control systems.The Green coding complies with MIL-STD-1472 human factors standards. The chemical-agent-resistant finish withstands decontamination procedures in NBC-protected command post equipment.Featuring Threaded Mating Lock, Shield Connection Front Side, these connectors implement TEMPEST shielding for classified systems. The multi-layer construction prevents compromising emanations in SIGINT equipment per NSA 94-106 specifications.The 1 single-tier design minimizes radar cross-section in stealth applications. This flat architecture reduces cavity resonances that could increase detectability in B-21 Raider avionics.
