FQ Series 4 Pin Waterproof Circular Plug Connector – Shell Size 14, IP67 Bayonet Lock

Product Overview

The FQ Series 4 Pin Waterproof Circular Plug Connector is developed for stable power and signal transmission in industrial electrical systems where environmental protection and reliable connections are essential. Manufactured in accordance with the DZ4Q/RE008-84 standard, the FQ series is an upgraded version of the traditional Q series, featuring improved sealing performance, a compact structure, and a user-friendly bayonet locking mechanism.

Designed with a 4-pin layout and 1.5 mm contacts, this connector is suitable for equipment that requires multiple electrical circuits within a compact interface. The advanced squirrel-cage elastic contact structure helps maintain consistent contact pressure throughout repeated mating cycles, while the anodized aluminum alloy shell provides durability and corrosion resistance. With an IP67 protection rating, the connector is well suited for industrial automation, outdoor electrical equipment, transportation systems, and other applications exposed to demanding operating conditions.

Key Features

-- Bayonet coupling mechanism enables fast installation and secure locking for efficient equipment assembly.

-- IP67 sealing design helps protect the connector from dust and temporary water exposure under normal operating conditions.

-- Gold-plated copper contacts provide stable electrical conductivity and help reduce oxidation over time.

-- Squirrel-cage elastic female contacts maintain reliable contact force and low contact resistance during repeated use.

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

-- Compact 4-pin configuration supports simultaneous transmission of power and control signals.

Working Principle

When the plug is connected to the matching receptacle, the bayonet locking system securely holds the connector in position. The precision gold-plated contacts establish stable electrical continuity, while the squirrel-cage elastic contact structure helps maintain consistent contact pressure under vibration or movement. Internal PBT insulation separates each circuit, and the sealing system assists in protecting the electrical connection from external environmental influences.

Typical Applications

-- Industrial automation equipment

-- Electrical control systems

-- Manufacturing machinery

-- Outdoor monitoring devices

-- Communication equipment

-- Marine electrical installations

-- Test and measurement instruments

-- Power distribution equipment
