Product Specification

FQ Series 19 Pin Waterproof Circular Socket – IP67 Bayonet Connector

Product Description

The FQ Series 19 Pin Waterproof Circular Socket is designed for dependable electrical connection and signal transmission in industrial and outdoor applications where reliable sealing and long-term performance are essential. Manufactured in accordance with DZ4Q/RE008-84, the FQ Series is an upgraded version of the traditional Q Series, offering improved waterproof capability, enhanced mechanical reliability, and a compact, lightweight design suitable for demanding operating environments.

This connector features a 19-pin configuration with gold-plated copper contacts, ensuring stable conductivity and low contact resistance for consistent signal and power transmission. Unlike conventional spring-contact designs, the female contact system adopts a highly reliable squirrel-cage elastic structure, providing uniform contact pressure, excellent electrical continuity, and outstanding resistance to vibration and mechanical shock. The bayonet locking mechanism allows quick and secure connection while reducing installation time and improving operational efficiency.

The anodized aluminum alloy housing, high-performance PBT insulator, and IP67-rated sealing provide excellent protection against dust, moisture, and environmental exposure. Designed for reliable operation across a wide temperature range, the FQ Series is suitable for equipment that requires durable waterproof electrical interconnections and long service life.

Key Features

-- IP67 waterproof protection for demanding environments

-- Reliable bayonet locking for quick installation and secure connection

-- 19-pin configuration for multi-circuit transmission

-- Gold-plated copper contacts with low contact resistance

-- Advanced squirrel-cage elastic contact structure

-- Compact and lightweight aluminum alloy housing

-- Excellent resistance to vibration, humidity, and environmental exposure
