The FQ Series 5-pin waterproof circular connector is a compact electrical connection solution designed for equipment where installation space is limited but reliable environmental protection is still required. With a Shell Size 14 housing, 5 contacts and IP67 protection, this socket combines a compact footprint with secure electrical and mechanical performance.
Developed as an improved version of the Q Series in accordance with the DZ4Q/RE008-84 standard, the FQ connector incorporates a squirrel-cage elastic contact structure rather than a conventional wire-spring design. This contact configuration helps maintain stable contact pressure and reliable electrical continuity while supporting resistance to vibration and mechanical impact.
-- Compact 5-pin design: Five contacts provide multi-circuit connection in a relatively small connector housing.
-- IP67 protection: Helps protect the mated connection from dust and temporary water immersion.
-- Bayonet coupling: Allows quick mating and locking for efficient installation and maintenance.
-- Elastic squirrel-cage contacts: Help provide stable contact engagement and consistent electrical performance.
-- Gold-plated copper contacts: Provide good conductivity and corrosion resistance.
-- Aluminum alloy shell: Anodized surface treatment provides additional surface protection.
-- Wide operating temperature: Suitable for environments from -55°C to +100°C.
When the plug and socket are connected, the elastic contact structure creates stable electrical contact between corresponding terminals. The bayonet mechanism then locks the connector through a short rotational movement, reducing installation time while maintaining secure mating. The sealing components work together with the connector housing to help prevent dust and water from reaching the contact area.
