Defense connectors are high-performance electrical connectors designed for extreme environments such as military, aerospace, etc. They have the characteristics of high protection, corrosion resistance, fast separation, and signal integration transmission. Here is the key information:

Protection level and environmental adaptability
IP67 protection: dustproof and waterproof, can be immersed in water for a short time (1 meter depth, no leakage for 30 minutes). ‌‌
Extreme temperature: The working temperature range is -66 ℃ to 200 ℃, and some models can reach -65 ℃ to 175 ℃. ‌
Salt spray/mold: The cadmium/nickel/titanium alloy shell can withstand salt spray for 500-2000 hours and mold test for 28 days. ‌

Structure and Performance
Quick locking: bayonet rotation, steel ball locking, or multi head thread locking, supporting direct insertion or rotary insertion, with low separation force. ‌‌
Mechanical lifespan: 500 cycles of insertion and extraction, with some models reaching up to 1000 cycles. ‌
Signal transmission: Supports optoelectronic signal integration, with contact resistance ≤ 10m Ω and insulation resistance ≥ 5000m Ω. ‌

Standards and Certification
MIL-DTL-38999: US military standard, suitable for tactical weapons and aerospace systems. ‌
GJB599: Chinese military standard, compatible with MIL-DTL-38999, requiring vacuum resistance and radiation protection. ‌

Application scenarios
Tactical weapons, satellites, shipborne systems, etc. need to work stably under harsh conditions such as vibration (10-2000Hz) and impact (300g).
