Product details
Designed for aerospace avionics, Amphenol ICC (Commercial Products)'s L77TWCH27W2S D-Sub Connectors meets DO-160G standards while reducing weight by 40% versus traditional connectors. The composite shell design maintains shielding effectiveness during 50,000-foot altitude cycling.The D-Sub, Combo configuration incorporates anti-vibration features that maintain contact integrity during 20G shock events.Receptacle, Female Sockets contacts employ quad-redundant springs that maintain continuity during 15G vibration per MIL-STD-810.The 27 (25 + 2 Coax or Power) layout includes arc-resistant spacing that prevents flashover at 35,000-foot equivalent altitudes.Precision-machined 2 contact arrays maintain alignment within 0.1mm during thermal cycling from -65 C to +125 C.Panel Mount variant features hermetic glass seals that maintain <1x10-9 atm-cc/sec helium leak rate.The 4 (DC, C) - 27W2 design provides 100dB shielding effectiveness from 10kHz to 18GHz per MIL-STD-461G.Signal and Coax or Power (Not Included) implementation uses beryllium-nickel alloys that maintain spring properties at cryogenic temperatures.The Housing/Shell (Unthreaded) system incorporates vibration-resistant hardware that meets NASM25027 torque retention requirements.Our Solder Cup methodology creates joints that survive 1000 thermal cycles from -65 C to +200 C.Steel, Tin Plated demonstrates >500-hour salt spray resistance per ASTM B117 with no measurable corrosion.The Gold surface treatment maintains <5m resistance after 500 hours of mixed flowing gas testing.Precision-controlled 16.0µin (0.41µm) ensures proper noble metal coverage after extended environmental exposure.The 7.5A design incorporates parallel current paths that reduce thermal resistance by 30%.
