FQ Series 3 Pin IP67 Waterproof Circular Socket Connector

Product Information

The FQ Series 3-pin waterproof circular socket connector provides a compact and sealed electrical interface for equipment requiring multiple contact positions within a small connector format. Developed as an improved version of the Q Series and manufactured according to the DZ4Q/RE008-84 standard, it combines IP67 protection, a bayonet locking system, and a reliable elastic contact structure for demanding electrical connection applications.

Unlike conventional wire-spring contacts, the female contacts adopt a squirrel-cage elastic structure. This design helps maintain stable contact pressure during operation, supporting reliable electrical continuity while reducing contact resistance. The structure also offers good resistance to vibration and mechanical impact, which can help maintain connection stability in equipment subject to movement or mechanical disturbance.

Key Characteristics

• 3-pin configuration provides flexible multi-contact electrical connection.

• IP67-rated protection helps protect the mated connection from dust and temporary water immersion.

• Squirrel-cage elastic female contacts support stable contact performance.

• Gold-plated copper contacts provide good electrical conductivity and corrosion resistance.

• Aluminum alloy shell with anodized surface treatment combines durability with relatively low weight.

• Bayonet connection enables fast mating and secure locking.

• Solder termination is suitable for equipment wiring and assembly.

• Operating temperature range of -55°C to +100°C supports a wide range of working environments.
