The FQ Series Waterproof Circular Connector Plug is a high-performance circular connector designed to provide secure and stable electrical connections for professional equipment and electronic systems. Manufactured according to the DZ4Q/RE008-84 standard, the FQ Series combines advanced waterproof design, compact structure, lightweight construction, and excellent connection reliability.
With a 5-pin configuration and 10A rated current capability, this plug connector provides an efficient solution for applications requiring both power transmission and signal connection within limited installation space. The compact circular structure helps simplify wiring layouts while maintaining strong mechanical performance.
The connector features a specially developed squirrel-cage elastic contact structure, which replaces conventional wire spring contact designs. This structure provides stable contact pressure, low contact resistance, and improved resistance to vibration and mechanical stress. The gold-plated copper contacts ensure excellent electrical conductivity and corrosion resistance, supporting reliable operation over extended service periods.
The bayonet quick-connection mechanism enables fast installation and secure locking between plug and socket. Combined with an aluminum alloy shell and anodized surface treatment, the connector offers a durable and lightweight housing design suitable for various industrial and electronic equipment.
5 Pin Efficient Connection Design -- Provides flexible power and signal transmission in a compact circular connector structure.
Stable 10A Current Performance -- Designed for applications requiring reliable electrical power connection and continuous operation.
Advanced Contact Structure -- Squirrel-cage elastic contacts maintain consistent contact pressure and improve connection stability.
IP67 Waterproof Protection -- Sealed structure helps prevent dust and water entry, enhancing environmental adaptability.
Fast Bayonet Locking System -- Allows quick connection and disconnection while maintaining secure mechanical locking.
Lightweight Aluminum Alloy Housing -- Anodized shell provides excellent mechanical protection with reduced weight.
