FQ Series 26 Pin Waterproof Circular Plug Connector – Shell Size 24

Product Overview

The FQ Series 26 Pin Waterproof Circular Plug Connector is developed for reliable signal and low-current power transmission in industrial electrical equipment that operates in demanding environments. Manufactured in accordance with the DZ4Q/RE008-84 standard, this connector features an upgraded sealing design that offers enhanced environmental protection compared with conventional Q series connectors.

With a compact shell size, high-density 26-pin configuration, and secure bayonet locking mechanism, the FQ series is suitable for applications requiring multiple electrical circuits within a limited installation space. Gold-plated copper contacts, a rugged aluminum alloy housing, and an optimized elastic contact structure work together to deliver stable electrical performance and long-term durability.

Key Features

-- High-density 26-pin layout supports multiple signal and control circuit connections in compact equipment.

-- IP67 protection rating helps protect the connector against dust and temporary water exposure when properly assembled.

-- Bayonet locking mechanism allows fast installation while maintaining a secure mechanical connection.

-- Gold-plated copper contacts provide reliable conductivity and help reduce contact resistance.

-- Squirrel-cage elastic contact structure improves contact stability and supports vibration-resistant performance.

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

Working Principle

Electrical signals and power are transmitted through precision-machined gold-plated contacts housed inside an insulated connector body. Once the plug is connected to the corresponding socket and secured with the bayonet coupling system, the internal elastic contacts maintain consistent contact pressure, helping ensure stable electrical continuity. The integrated sealing structure assists in protecting the connection from moisture, dust, and external contaminants under specified operating conditions.

Typical Applications

-- Industrial automation systems

-- Electrical control cabinets

-- Instrumentation equipment

-- Communication systems

-- Process control devices

-- Railway electrical equipment

-- Outdoor monitoring systems

-- Power distribution equipment
