FQ14 Series 7-Pin Square Flange Male Socket
FQ Series 7 Pin IP67 Waterproof Circular Socket Connector
Product Information
The FQ Series 7-pin waterproof circular socket connector is designed for equipment that requires multiple electrical contacts within a compact circular interface. With seven 1.0 mm contacts, this model provides more connection positions while maintaining the practical dimensions of a Shell Size 14 connector. Its combination of IP67 protection, bayonet locking, and stable elastic contacts makes it suitable for reliable electrical integration in demanding equipment environments.
The female contact system uses a squirrel-cage elastic structure instead of a traditional wire-spring design. This structure provides consistent contact engagement and helps maintain reliable electrical continuity during vibration and mechanical impact. Gold-plated copper contacts support good conductivity and corrosion resistance, while the aluminum alloy shell with anodized treatment provides a lightweight and durable housing.
