FQ Series 4 Pin IP67 Waterproof Circular Socket Connector

Product Information

The FQ Series 4-pin waterproof circular socket connector is designed for equipment requiring multiple electrical contacts while maintaining a compact and sealed connection interface. Based on the improved Q Series design and manufactured according to the DZ4Q/RE008-84 standard, this connector combines a 4-pin contact configuration, 10A rated current, IP67 protection, and a quick bayonet locking structure.

Its female contacts feature a squirrel-cage elastic structure rather than a conventional wire-spring design. The elastic contact arrangement helps maintain stable contact pressure and reliable electrical continuity during operation. It also supports low contact resistance and good resistance to vibration and mechanical impact, helping the connection remain stable when installed in equipment subject to movement or environmental disturbance.

Key Characteristics

• 4-pin configuration provides multiple electrical connection points in one compact interface.

• 10A rated current supports a range of equipment power and electrical connection requirements.

• IP67 protection helps prevent dust ingress and provides protection against temporary water immersion when properly mated.

• Squirrel-cage elastic female contacts provide stable contact engagement.

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

• Aluminum alloy shell provides a lightweight and durable connector housing.

• Anodized surface treatment improves the surface durability of the shell.

• Bayonet locking enables quick mating and secure retention.

• Solder termination facilitates direct wiring during equipment assembly.
