A complete connector and harness portfolio engineered for satellites, launch vehicles, avionics and deep-space exploration systems

Vacuum conditions, low temperatures, intense radiation, launch shock, long-term micro-vibration, vacuum outgassing and low residual magnetism make space one of the most demanding environments for electronic interconnect systems. From satellite constellations and launch vehicles to space stations, lunar exploration and commercial satellite missions, reliable connection technology is essential to mission performance and system safety.
Yonggui continues to develop aerospace-grade interconnect solutions and a comprehensive connector product portfolio to support stable, reliable and high-performance system integration for commercial aerospace and key space applications. |
