How to know if a USB-C cable is waterproof
If you need extra protection for your USB cables, knowing how to tell if they're waterproof beforehand is important. Here's how to check a cable's rating.
When selecting a USB-C cable that is waterproof, it is crucial to verify the IP rating provided by the manufacturer. USB-C cables with waterproof capabilities can be found in various types, including male, female, and angled cables. These cables often come sealed or packaged with gaskets to protect against water ingress. The International Electrotechnical Commission (IEC) standardizes water resistance through the Ingress Protection code IEC 60529, which indicates the level of protection against solids (first number) and liquids (second number).
Waterproof USB-C cables typically carry an IP67 or IP68 rating, meaning they can withstand immersion in water for limited periods.
These cables are commonly used in demanding environments such as manufacturing, construction, maritime work, and electric vehicle charging systems. Water exposure poses several risks, including short circuits, corrosion, overheating, and potential fire hazards. Therefore, it is advisable not to plug a wet USB-C cable into any device. USB cable protection generally employs silicone rubber seals, gaskets, or locking collars to prevent water from entering the connector.
Industrial-grade waterproof cables made from tough materials like neoprene or fluoroelastomer (FKM) offer enhanced resistance to chemicals and solvents. If the contacts are free of corrosion after drying, the cable can typically be used again after drying. To dry a waterproof USB-C cable, disconnect it, shake the connector to expel water, and allow it to air dry for 24 to 48 hours.
Avoid using heat sources like hair dryers, as they can damage the cable, and avoid using rice, as it may introduce grit and dust into the connector. If the cable becomes hot during use after drying, it should be replaced immediately.
Brands such as Atlavox, Yale, and L-Com manufacture waterproof USB-C cables, and these products are available at reputable retailers including Amazon. The cost of basic waterproof cables ranges from around ten dollars, while more rugged options for harsh environments can cost significantly more. Always check the official IP rating before purchasing to ensure the cable meets your required level of water resistance.
