JY27508E12B35PN High-Reliability Circular Connector, Vibration Resistant, Gold-Plated Contacts, Bayonet Coupling, Multi-Pin Electrical Plug

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.

Contact resistance and rated current of the contact parts:

Electromagnetic interference shielding: at 100 MHz-1 GHz, minimum attenuation is 45 dB; Withstand voltage:V

Insulation resistance: Under normal conditions ≥ 5000 MΩ

Electrical continuity between the shell and interior: Class B ≤ 2.5 m Ω

Moisture condition: ≥ 100 M Ω

F class ≤ 1.0 m Ω E class ≤ 50 m Ω
