J599Ⅲ Series Fiber Optic Connector/ Optic & Electronic Hybrid Connector
Product Description
The J599Ⅲ Series Fiber Optic / Optic & Electrical Hybrid Connector is a military-grade circular connector designed for reliable transmission of optical and electrical signals in harsh environments. Based on the GJB599B (MIL-DTL-38999 Series III) interface, it supports high-density signal integration and offers excellent resistance to vibration, shock, fluids, and extreme temperatures.
With flexible housing materials, multiple keying options, and optional airtight adapter sockets, this series is widely used in aerospace, aviation, naval, electronic, and weapon systems requiring high reliability and long service life.
Key Features
- GJB599B (MIL-DTL-38999) Series III compatible interface
- Supports integrated transmission of optical and electrical signals
- Triple-screw coupling mechanism for fast connection and anti-loosening
- 5-key positioning design with blind-mate and error-proof insertion
- Multiple shell materials and surface treatments for different environments
- Optional airtight adapter socket to reduce cable constraints
- Excellent resistance to vibration, shock, fluids, and salt mist
