CNLINKO Waterproof Connectors are industrial-grade, sealed interconnect solutions engineered to provide reliable power, signal, and data transmission in harsh, wet, or dust-prone environments. Manufactured by CNLINKO Electric, these connectors are globally recognized for their robust IP-rated weatherproofing and fast-locking mechanisms.
​Key Waterproof & Technical Specifications ​
ₒ High Ingress Protection (IP Rating): Certified to IP67, IP68, and IP69K standards—guaranteeing 100% dust tightness and continuous water resistance against submersion or high-pressure water jets.
ₒ ​Sealing Technology: Utilizes high-grade silicone and O-ring gaskets at panel mounts, cable glands, and mating interfaces to block water, oil, and moisture ingress.
ₒ ​Corrosion & UV Resistance: Built with flame-retardant PBT engineering plastics or nickel/chrome-plated zinc alloy housings, allowing reliable outdoor operation under intense UV exposure and saltwater spray.
ₒ ​Connection Speed: Features quick-connect mechanisms (push-pull, bayonet, or snap-button locks) that create an instant watertight seal upon connection.
​ₒ Operating Temperature: Maintains structural and electrical integrity across wide thermal ranges (typically -40^\circ\text{C} to +85^\circ\text{C}). ​
Supported Signal & Power Interfaces
​Power Connectors: 2-pin to 5-pin layouts supporting up to 50\text{ A} / 500\text{ V} for heavy machinery and outdoor power feeds. ​
ₒ Signal Connectors: Multi-pin configurations (6 to 24+ pins) for sensors, control systems, and audio/video signals.
ₒ ​Data & Optical Interfaces: Watertight RJ45 (Ethernet), USB 2.0/3.0, Type-C, and Fiber Optic connectors for outdoor communications and data transfer.
​Primary Applications ​
1. Outdoor LED Screens & Lighting: Power and data distribution for stadium displays, architectural lighting, and stage equipment. ​
2. Marine & Naval Electronics: On-deck instrumentation, fishfinders, navigation systems, and electric boats.
3. ​Solar & Renewable Energy: Inverters, solar tracking systems, and outdoor battery energy storage systems (BESS).
4. ​Industrial Automation & AGVs: Waterproof connections for outdoor robotics, automated guided vehicles, and agricultural machinery.
