JY27466T13F989N High-Reliability Circular Connector, Wall-Mount Electrical Receptacle, EMI Shielded Bayonet Interconnect Connector
The GJB599B MIL-DTL-38999 Series I Quick-Release EMI Shielded Connector is designed for compact, lightweight, and high-density circuit signal connection. It features quick-release coupling, EMI/RFI shielding, five-key positioning, anti-mismating protection, and detachable crimp contacts for reliable connection performance.
This series provides 9 shell sizes, multiple contact layouts, and various receptacle mounting styles, including box-type, wall-mounted, front-mounted, rear-mounted, and jam-nut options. Rear accessories comply with GJB1784, supporting stable cable assembly and system-level integration.
The connector is manufactured with aluminum alloy, stainless steel, or titanium alloy shells. Contacts are made of gold-plated copper alloy and support crimp, solder, and PCB termination. With 500-cycle mechanical durability, 10–2000 Hz sine vibration resistance, random vibration resistance, and 300g half-sine shock resistance, it is widely used in aviation systems, defense electronics, communication equipment, industrial control systems, and high-reliability signal interconnection applications.
