FQ Series 19 Pin Waterproof Circular Plug – IP67 Bayonet Connector

Product Description

The FQ Series 19 Pin Waterproof Circular Plug is a high-performance circular connector designed for dependable electrical connection and signal transmission in industrial equipment operating in demanding environments. Manufactured in accordance with the DZ4Q/RE008-84 standard, the FQ Series is an upgraded version of the traditional Q Series, offering enhanced waterproof capability, improved sealing performance, and a compact, lightweight construction. Its advanced internal design ensures reliable operation while reducing maintenance requirements over long-term use.

This 19-pin plug is equipped with gold-plated copper contacts, delivering excellent electrical conductivity, low contact resistance, and stable transmission performance. The connector adopts an innovative squirrel-cage elastic contact structure, replacing conventional wire spring designs to provide more uniform contact pressure, improved vibration resistance, and longer service life. This optimized contact system helps maintain consistent electrical performance even after repeated mating cycles.

The connector features a bayonet quick-locking mechanism, allowing fast connection and secure engagement with minimal installation effort. An anodized aluminum alloy shell provides outstanding mechanical strength and corrosion resistance, while the high-performance PBT insulator ensures excellent electrical insulation. With an IP67 protection rating, the connector effectively prevents dust and water ingress, making it suitable for industrial equipment exposed to moisture, vibration, and challenging operating conditions.

Key Features
