FQ Series 12 Pin Waterproof Bayonet Plug Connector – IP67 Circular Electrical Connector

Product Description

The FQ Series 12 Pin Waterproof Circular Plug Connector is designed for reliable electrical connection and signal transmission in industrial equipment operating under demanding environmental conditions. Manufactured in accordance with the DZ4Q/RE008-84 standard, the FQ series is an enhanced version of the traditional Q series, offering improved sealing performance, a compact structure, and dependable mechanical reliability. Its lightweight aluminum alloy housing and precision-engineered internal components make it suitable for applications requiring long-term connection stability.

One of the key design features of the FQ series is the highly reliable squirrel-cage elastic contact structure, which replaces the conventional wire spring design. This optimized contact system helps maintain consistent electrical conductivity while improving resistance to vibration and mechanical shock. Combined with a bayonet quick-lock mechanism, the connector allows fast installation and secure engagement, making it an efficient solution for a wide variety of industrial electrical systems where stable performance and environmental protection are important.

Key Features

-- Manufactured in accordance with the DZ4Q/RE008-84 standard.

-- IP67-rated sealing helps protect against dust and temporary water immersion under specified conditions.

-- Squirrel-cage elastic contact structure provides reliable contact stability.

-- Bayonet locking mechanism enables quick connection and easy maintenance.

-- Gold-plated copper contacts support stable electrical conductivity and corrosion resistance.

-- Anodized aluminum alloy shell offers excellent mechanical strength and surface durability.

-- Compact and lightweight design simplifies installation in space-limited equipment.

Working Principle

The connector establishes electrical continuity through precision-machined gold-plated contacts housed inside an insulated body. After the plug is inserted into the matching receptacle, the bayonet locking mechanism securely fixes both connector halves together, helping maintain stable contact pressure during operation. The sealed housing and insulating components protect the internal contacts from external environmental influences while ensuring reliable signal and power transmission.
