Water and dust proof connectivity products are defined by their Ingress Protection (IP) numbers. The first number after IP is for the part'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 equipment is the most commonly found in the connectivity market. It is 100% protected against solid objects like dust and sand, and it has been tested to work for at least 30 minutes while under 15cm to 1m of water.
Meaning:IP67 indicates that the housing is multi-purpose and meets the requirements of spraying water or short time and continuous immersion.
Number 6 means:Fully protect internal circuit from dust intrusion.
Number 7 means:When immersed in less than 1m water, the internal parts can be protected for not less than 30min.
