1703056

Phoenix Contact's 1703056 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 PCB Pins - Straight 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 1.750" (44.45mm) 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 2 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 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 300 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 66 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.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.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.
