 SF Circular Connector - Reliable Connection for Industrial Environments

Looking for a robust, easy-to-operate, and weather-resistant connectivity solution for your industrial equipment? Our SF Series Circular Aviation Connector is engineered to deliver uncompromising performance in the harshest conditions, making it the top choice for engineers and manufacturers worldwide. With its push-pull quick-locking design, IP67 waterproof and dustproof rating, and durable zinc alloy (brass with chrome plating) construction, this connector ensures stable signal and power transmission even in extreme temperatures, vibrations, and humidity.

SF Circular Connector

SF Circular Connector: Key Features That Set Us Apart

Push-Pull Quick-Locking System: Effortless mating and unmating with a "click" confirmation, eliminating the need for tedious screwing. The self-locking mechanism prevents accidental disconnection caused by vibration or external impact, ensuring secure connections in mobile or high-vibration equipment like robotic arms and rail transport systems.

SF Connector


 Durable & Corrosion-Resistant Construction: Crafted from high-quality zinc alloy (brass with chrome plating), the shell offers excellent corrosion resistance and mechanical strength. The gold-plated contacts enhance conductivity, reduce contact resistance (≤5mΩ), and ensure long-term reliability even in corrosive environments like coastal or industrial areas.
