Round flange connector

Product Overview： The Round Flange Waterproof Connector is a heavy-duty panel-mount circular connector designed for permanent fixed installation and long-term reliable wiring in industrial, outdoor, automotive and marine environments. Unlike conventional floating plug connectors that are prone to loosening under vibration and frequent plugging, this flange-type connector features an integrated round flange base with preset mounting holes, enabling rigid locking on equipment enclosures, control panels and mounting surfaces. It effectively prevents displacement, rotation and poor contact caused by mechanical vibration, pulling and environmental erosion. Supporting multiple core specifications from 2 cores to 8 cores with fully isolated circuits, this fixed circular connector enables stable synchronous transmission of power and multi-channel signals without crosstalk. Built with one-piece overmolding sealing and industrial anti-aging materials, it delivers superior IP67 waterproof, dustproof, anti-corrosion and anti-vibration performance. Ideal for harsh working conditions including outdoor exposure, humid workshops, dusty industrial sites and vibrating mechanical systems, it serves as a high-reliability fixed connection solution for industrial automation, monitoring devices, automotive fixed harnesses and marine precision instruments.

Application field： Industrial Automation，Outdoor Monitoring & Lighting:，Automotive & Special Vehicles，Marine & Offshore Equipment，Precision Instruments & Smart Devices

Core Features & Advantages

Rigid Round Flange Fixed Mount Structure: Equipped with an integrated circular flange base and standard mounting holes, this connector supports fast, firm embedded panel installation. It eliminates connector loosening, shifting and falling off under long-term vibration and external pulling, ensuring stable and durable fixed connection for continuously operating equipment.

Multi-Core Isolated Transmission (2-8 Cores): Available in diversified core configurations with fully independent insulated channels. Effectively isolates current interference and signal crosstalk, achieving loss-free power supply and high-precision signal transmission. Flexible enough to match various low-power and multi-signal control wiring requirements of precision equipment.

IP67 Industrial Waterproof & Dustproof Grade: Adopts integral overmolding sealing technology paired with high-elastic waterproof rubber gaskets to form a fully enclosed protective structure. It resists water splashing, temporary immersion, dust accumulation, moisture and oxidation aging, maintaining stable electrical performance in all-weather harsh environments.

High-Strength Vibration-Resistant Durability: Thickened flange shell made of high-toughness flame-retardant engineering plastic features excellent compression resistance, impact resistance and deformation resistance. It withstands high-frequency vibration and extreme temperature changes, ensuring structural stability for long-term fixed installation.

Premium Conductive & Insulating Performance: Internal pins adopt high-purity oxygen-free copper with anti-oxidation nickel plating, ensuring ultra-low resistance, high conductivity and long-term corrosion resistance. High-standard insulating materials prevent short circuits and electric leakage, guaranteeing safe and stable circuit operation.

Universal Compatibility & Easy Maintenance: Standard industrial size and wiring specifications perfectly match our full series of waterproof harnesses and mating plug connectors. Tool-friendly fixed mounting simplifies on-site installation, replacement and daily maintenance, greatly improving project wiring efficiency.
