What is the difference between IP67 and IP ?

Ingress Protection (IP) ratings are a standard measurement used to define the level of protection provided by electronic devices against solid particles like dust and water. The IP rating is composed of two digits: the first digit represents the level of protection against solid objects, while the second digit indicates the level of protection against liquids.

IP65 and IP67 are two common IP ratings found in the market and are frequently encountered in the specifications of smartphones, smartwatches, and other electronic devices. IP65 rated devices are considered "dust-tight," meaning they provide complete protection against dust ingress. Additionally, IP65 rated devices can resist low-pressure jets of water from all directions. This makes them suitable for use in rainy conditions or situations where splashing might occur.

On the other hand, IP67 rated devices offer a higher level of protection against both dust and water. IP67 devices are also deemed "dust-tight," but what sets them apart is their ability to withstand the immersion of up to 1 meter of water for a duration of 30 minutes. This means IP67 rated devices offer superior water resistance and can handle accidental drops into water or exposure to water sports activities.

IP66-rated devices are similar to IP67 but with some limitations. They are also dust-tight, but they can only handle powerful jets of water up to a depth of 0.5 meters. This means they are suitable for use in harsh environments or for devices that require a higher level of protection against water.

In conclusion, IP65 and IP67 are both common IP ratings used to provide protection against solid particles and liquids. IP65-rated devices are suitable for use in indoor environments, while IP67-rated devices are better suited for outdoor use or situations where heavy rain or water activities may occur.
