Technical Features & Advantages
1. Military-Grade Reliability Design
The 38941-22L strictly adheres to MIL-DTL-38999 Series III standards, featuring an aluminum alloy housing and triple-threaded self-locking structure to maintain reliable connections under extreme vibration, shock, and thermal cycling conditions. Withstands 500-hour salt spray testing and operates across a wide temperature range from -65°C to +200°C, ensuring stable performance in harsh environments like marine, desert, and polar conditions.
2. High-Density Signal Transmission
22-pin configuration within a 25-pin housing enables high-density signal transmission. Paired with #20HD high-density contacts, it transmits more data channels within limited space. Supports high-speed differential signals (USB 3.0, Ethernet) to meet modern avionics bandwidth demands.
3. Rapid Locking and Blind Mating Capability
Triple-threaded self-locking design enables 360° quick rotation locking with torque 50% lower than standard 38999 connectors, providing clear tactile feedback. Supports blind mating for enhanced operational efficiency during battlefield deployment or equipment maintenance.
4. 360° EMI Shielding and Grounding
A full-metal housing combined with EMI spring fingers and conductive sealing rings achieves 360° electromagnetic shielding. Shielding effectiveness reaches 100dB (100MHz-10GHz), effectively suppressing electromagnetic interference and protecting sensitive signal integrity.
5. Environmental Sealing and Corrosion Resistance
IP67 protection rating combined with fluorosilicone rubber seals prevents ingress of dust, moisture, and corrosive gases. Housing surface treatments include military-green cadmium plating (compliant with MIL-STD-871), nickel plating, or anodizing to suit diverse corrosive environments.
