Product Description
The J599Ⅲ Series High & Low Frequency Mixed Connector is a high-reliability circular interconnect solution designed for the integrated transmission of power, microwave/high-frequency signals, high-speed data, control signals, and optical fibers in harsh aerospace and defense environments.
Based on the GJB599B / MIL-DTL-38999 Series III interface, the connector combines high contact density, excellent electromagnetic shielding, and superior vibration resistance, enabling multi-signal integration within a compact and lightweight form factor.
