Product Specification

FQ Series 9 Pin Waterproof Circular Connector Plug – Shell Size 30

Product Description

The FQ Series 9 Pin Waterproof Circular Connector Plug is engineered for dependable electrical connections in environments where moisture, dust, vibration, and frequent mating are common. Manufactured in accordance with the DZ4Q/RE008-84 standard, the FQ series is an upgraded version of the traditional Q series, offering significantly improved waterproof sealing and overall connection reliability.

One of the key features of this connector is its high-performance squirrel-cage elastic contact structure, which replaces the conventional wire spring design. This advanced contact system provides lower contact resistance, more stable electrical conductivity, and enhanced resistance to vibration and mechanical shock. Combined with a durable anodized aluminum alloy shell and an efficient bayonet locking mechanism, the connector ensures quick installation and secure operation even in demanding industrial environments.

Designed for long-term service, the FQ series delivers excellent sealing performance, compact dimensions, and lightweight construction, making it an ideal solution for both power and signal transmission applications.
