J599-26FB99SN Circular Connector, MIL-DTL-38999 Series, Square Flange Receptacle

Engineered for equipment exposed to vibration, shock, and mechanical movement, this connector uses a triple-start threaded quick-locking structure with anti-loosening protection to ensure dependable connection stability. The design combines rapid mating, strong locking force, and reliable resistance to accidental disengagement, making it suitable for rugged electronic systems and harsh operating environments.

Its contact structure supports multiple specifications, including 22D, 20#, 16#, 12#, and 10# contacts, covering working diameters from Φ0.76 mm to Φ3.15 mm. With low contact resistance and rated current capacity up to 40 A, the connector can meet different signal and power transmission requirements within compact system designs.

The anti-oblique insertion contact design enhances mating reliability and reduces the risk of assembly errors. With high insulation resistance and controlled shell conductivity across different finish classes, the connector provides stable electrical performance, effective grounding, and reliable long-term operation.
