4-1377173-5

The 4-1377173-5 from TE Connectivity AMP Connectors sets new benchmarks in Terminals - Wire Pin Connectors for aerospace avionics. These connectors are qualified to MIL-DTL-38999 Series III standards with triple-redundant contact systems. The lightweight titanium housing provides 40% weight savings versus traditional designs while surviving 1000G shock loads.Precision Circular - 0.071" (1.80mm) Dia contacts maintain signal integrity across 10MHz-18GHz avionics databuses. The quadrax variants feature hermaphroditic designs that eliminate gender-mating errors in fly-by-wire systems.The 0.264" (6.71mm) pin length is optimized for press-fit installation in rigid-flex PCBs used in satellite payloads. The controlled depth stops prevent over-insertion in blind-mate radar array connections.With 0.813" (20.65mm) dimensions, these connectors meet ARINC 600 form factors while providing 25% more contacts. The modular design allows mixed signal/power configurations in aircraft LRUs.Supporting 14-16 AWG wiring, these terminals utilize cold-welded terminations that survive 5000 thermal cycles from -65 C to +200 C in jet engine monitoring systems.The 0.115" ~ 0.190" (2.92mm ~ 4.83mm) range includes space-qualified materials that outgas <0.1% TML in vacuum environments. The radiation-hardened variants withstand 100krad(Si) total dose in LEO satellite constellations.Insulated options feature atomic oxygen-resistant coatings for ISS external connections, tested per NASA SSP 30472 requirements.The Crimp process creates gas-tight joints that maintain <10m resistance after 1000 hours salt spray exposure per MIL-STD-810H Method 509.6.Advanced Serrated Termination include embedded fiber optic channels that provide EMI-immune data transmission alongside power contacts in next-gen flight control systems.Blue coding follows AS50881 standards for aircraft wiring systems. The high-contrast variants improve maintainability in low-light flight deck conditions.
