FQ Series 5 Pin Waterproof Circular Plug Connector – Shell Size 14

Product Description

The FQ Series 5 Pin Waterproof Circular Plug Connector is designed for secure power and signal connections in industrial equipment operating in environments where moisture, vibration, and frequent connection cycles are common. Manufactured in accordance with the DZ4Q/RE008-84 standard, the FQ series represents an upgraded solution based on the traditional Q series, offering enhanced sealing performance and a more reliable contact structure.

This connector features a 5-pin configuration with a compact shell size, making it suitable for equipment requiring multiple electrical circuits within limited installation space. The innovative squirrel-cage elastic female contact structure provides stable contact pressure and low contact resistance throughout repeated mating operations. Combined with a quick bayonet locking system and an IP67-rated sealing design, the connector supports dependable performance in a wide variety of industrial electrical applications.

Key Features

-- Bayonet locking mechanism allows quick installation while helping maintain a secure mechanical connection.

-- IP67 protection rating helps reduce the effects of dust and water during normal industrial operation.

-- Squirrel-cage elastic contact design provides stable contact force and supports consistent electrical transmission.

-- Gold-plated copper contacts help improve electrical conductivity and reduce surface oxidation.

-- Lightweight aluminum alloy shell with anodized finish offers corrosion resistance and mechanical durability.

-- Compact 5-pin configuration supports both power and signal transmission in space-limited equipment.

Working Principle

Electrical power or control signals are transmitted through precision gold-plated contacts after the connector is fully engaged. The bayonet coupling securely locks the plug to the mating connector, helping maintain stable electrical continuity under vibration or movement. Internal insulation separates each contact while the sealing structure assists in protecting the connection from external environmental influences during normal operation.

Typical Applications

-- Industrial automation systems

-- Electrical control cabinets

-- Outdoor monitoring equipment

-- Communication devices

-- Test and measurement instruments

-- Marine electrical applications

-- Portable industrial equipment

-- Machine tools and manufacturing systems
