The JONHON JYS Series (GJB599 Series) represents the cutting edge of high-density, ultra-miniature circular connectors designed for extreme, space-constrained environments. Engineered to combine an ultra-lightweight profile with exceptional mechanical strength, these connectors feature a rapid bayonet coupling mechanism for secure, vibration-resistant mating. Compliant with the rigid Q/21EJ733 technical specification, the JYS series offers unparalleled environmental resilience, withstanding temperatures from -55°C to 175°C, high vibration up to 2000Hz, and up to 1000 hours of salt spray corrosion (E-class). Available in aluminum alloy or stainless steel shells with both crimp-removable and PCB tail contact options, it is the premier interconnect solution for advanced aerospace, military electronics, and high-end industrial UAV systems where every millimeter and gram counts
