What does IP67 mean? I need waterproof cables, connectors, and adapters

Water and dust proof connectivity products are defined by their Ingress Protection (IP) numbers. The first number after IP is for the component's protection against solid objects like dust and sand. This number can range from 0, meaning no protection against dust and sand, and 6, meaning 100% protection against dust and sand. 

The second number after IP is for the part's protection against liquids.  It ranges from 0 to 8.  

IP67 cables and components such as connectors and NEMA enclosures are most commonly found in the industrial or military connectivity applications. IP67 rated products are 100% protected against solid objects like dust and sand and have been tested to work for at least 30 minutes while under 15cm to 1m of water.  

If you're looking for an IP67 waterproof assembly or a IP67 power connector, IP67 rated enclosure, or an IP67 connector or any of our other items with an IP67 waterproof rating, then explore our website to see a wide selection of waterproof and dustproof connectivity products all with same day shipping.
