JY27508E12B35PN High-Reliability Circular Connector, Vibration Resistant, Gold-Plated Contacts, Bayonet Coupling, Multi-Pin Electrical Plug
Product Details
electrical circular connector
The GJB599B MIL-DTL-38999 Series II EMI Shielded Circular Connector is a compact, lightweight connector designed for circuit signal connection. It complies with the MIL-DTL-38999 Series II standard and adopts a card-type quick connection design for reliable and efficient electrical interconnection.
This series features small size, light weight, short shell length, EMI/RFI shielding, detachable press-fit contacts, and anti-mismating contact protection. For limited-space applications where plugging and unplugging are difficult, pre-installed contacts in the receptacle are recommended.
The connector is available with aluminum alloy or stainless-steel shells. Contact materials use gold-plated copper alloy and support crimp, solder, and PCB mounting. With a mechanical life of 500 mating cycles, random vibration resistance from 100–1000 Hz at 1 g²/Hz, and 300g half-sine shock resistance, this series is suitable for lightweight electronic systems, communication equipment, industrial control devices, and compact signal interconnection applications.
