Testing confirms survivability in 50kV/m transient electromagnetic fields.With 100 (4 x 25), the socket supports ruggedized avionics designs. The reinforced grid pattern withstands 100G mechanical shock per MIL-STD-810H.0.050" (1.27mm) spacing maintains signal integrity in jamming environments. Testing shows <-65dB crosstalk despite intentional RF interference.The Tin-Lead finish resists corrosion in salt fog. Testing per MIL-STD-202G Method 101 shows no degradation after 1000 hours.200.0µin (5.08µm) thickness ensures long-term reliability. Accelerated life testing predicts 20-year service in naval applications.Constructed with Phosphor Bronze, the socket withstands ballistic impacts. Testing confirms functionality after 30g 11ms half-sine shock pulses.The Through Hole design prevents loosening in vibration. Testing per MIL-STD-167-1 shows zero connection loss at 29Hz-2kHz random vibration.Incorporating Closed Frame, the socket provides NBC (Nuclear, Biological, Chemical) protection. Sealing tests confirm operation after immersion in decontamination solutions.Solder technology ensures reliability in high-altitude conditions. Testing confirms operation at 70,000 feet with <1% contact resistance change.The 0.050" (1.27mm) spacing accommodates armored cable terminations. Mechanical testing confirms 500N pull-out resistance for field-replaceable connections.Tin-Lead plating prevents galvanic corrosion. Testing in marine environments shows no measurable degradation after 5 years.The 200.0µin (5.08µm) finish ensures reliability after sand abrasion. Testing per MIL-STD-810G Method 510.5 shows <5% contact resistance change.The Phosphor Bronze posts resist stress corrosion cracking. Testing per ASTM G36 shows no cracking after 1000 hours in boiling MgCl2.Liquid Crystal Polymer (LCP) housing material provides radar absorption. Testing shows -20dB RCS reduction compared to metal housings.
