The FQ Series Waterproof Circular Connector is a high-performance electrical connection solution designed for applications requiring reliable signal and power transmission under demanding environmental conditions. Manufactured according to the DZ4Q/RE008-84 standard, this series is an upgraded version of the traditional Q series with improved sealing performance, enhanced structural strength, and optimized connection reliability.
Featuring a compact design, lightweight aluminum alloy shell, and advanced waterproof structure, the FQ Series connector provides stable electrical performance while saving installation space. The connector adopts a bayonet quick-locking mechanism, allowing fast and secure connection with simple operation, making it suitable for various professional equipment and electrical systems.
The female contact system uses a specially designed squirrel-cage elastic structure instead of traditional wire spring contacts. This innovative contact design provides stable contact pressure, lower contact resistance, excellent vibration resistance, and improved connection durability during repeated operations.
Enhanced Waterproof Performance -- IP67 protection design effectively prevents dust and water ingress, improving equipment reliability in harsh environments.
Reliable Contact Structure -- Gold-plated copper alloy contacts ensure excellent conductivity, corrosion resistance, and long-term stable electrical performance.
Quick Bayonet Connection -- The bayonet locking structure enables convenient installation and removal, reducing assembly time.
Compact and Lightweight Design -- Aluminum alloy housing with anodized surface treatment provides strength while maintaining low weight.
High Environmental Adaptability -- Designed to operate under wide temperature ranges and high humidity conditions.
