FQ Series 2 Pin Waterproof Circular Plug Connector – Shell Size 14, IP67 Bayonet Connector

Product Description

The FQ Series 2 Pin Waterproof Circular Plug Connector is designed for secure power transmission and dependable electrical connections in industrial equipment exposed to moisture, vibration, and challenging operating conditions. Manufactured in accordance with the DZ4Q/RE008-84 standard, the FQ series is an enhanced version of the traditional Q series, featuring improved sealing performance, a compact structure, and a convenient bayonet locking mechanism.

Equipped with a 2-pin configuration and 1.5 mm contacts, this connector is well suited for applications requiring stable low-frequency AC or DC power connections. The female contact adopts an advanced squirrel-cage elastic structure, replacing the conventional wire spring design to provide consistent contact pressure, low contact resistance, and reliable electrical performance during repeated mating cycles. Its lightweight aluminum alloy housing and IP67 protection make it a practical solution for industrial automation, outdoor equipment, and control systems.

Key Features

-- Bayonet connection design enables quick installation and secure locking without complicated assembly procedures.

-- IP67 protection rating helps reduce the effects of water and dust in industrial and outdoor applications.

-- Squirrel-cage elastic contact structure supports stable conductivity and reliable contact performance.

-- Gold-plated copper contacts help improve electrical transmission while reducing oxidation and wear.

-- Aluminum alloy shell with anodized surface treatment provides mechanical strength and corrosion resistance.

-- Compact 2-pin design is suitable for equipment requiring efficient power transmission with limited installation space.

Working Principle

The connector establishes an electrical connection when the plug is inserted into the matching receptacle and secured using the bayonet locking mechanism. Gold-plated contacts provide stable current transmission, while the elastic contact structure helps maintain reliable contact force during vibration or repeated operation. Internal insulation separates the electrical circuits, and the sealing structure assists in protecting the connection from environmental influences during normal use.

Typical Applications

-- Industrial automation equipment

-- Electrical control panels

-- Power supply systems

-- Outdoor electrical devices

-- Communication equipment

-- Test and inspection instruments

-- Marine electrical applications
