In the world of electronics and technology, there are various standards and ratings that help determine the degree of protection offered by a device against elements such as water and dust. Two popular ratings that often confuse consumers are IP66 and IP68. These ratings refer to the levels of ingress protection provided by electronic devices, especially those exposed to harsh environments such as industrial settings or outdoor usage. In this article, we will delve into the differences between IP66 and IP68, and evaluate which rating provides better protection.
Understanding IP66
IP66 is an international standard that rates the protection level of an electronic device against solid objects (represented by the first digit '6') and water resistance (represented by the second digit '6'). A device with an IP66 rating means it is completely protected from dust and other solid particles and can withstand powerful jets of water without any damage. The '6' rating for solids ensures that no particles larger than 50mm can enter the enclosure, while the '6' rating for water means the device can withstand high-pressure water from all directions without penetration.
Exploring IP68
IP68 is also an international standard that rates the protection level of an electronic device, but it offers an even higher degree of protection compared to IP66. The '8' rating for solids means the device is fully protected against dust, just like IP66. However, the difference lies in the '8' rating for water resistance. A device with an IP68 rating can be submerged in water beyond 1 meter for extended periods without any harm. While IP66 protects against powerful water jets, IP68 goes a step further to ensure complete waterproofing, making it suitable for activities such as swimming or diving.
Which is Better?
When it comes to determining which rating is better, it depends on the specific requirements and usage scenario. IP66 offers excellent protection against dust and high-pressure jets of water, making it ideal for most applications such as outdoor lighting fixtures or industrial machinery exposed to splashes. However, if you require a device that can withstand submersion in water for long durations or operate in extremely wet environments, then IP68 is the way to go. For example, smartphones with an IP68 rating are more suitable for individuals who enjoy water sports or work in maritime industries.
In summary, both IP66 and IP68 ratings provide considerable protection against solids and liquids, but the difference lies in the level of water resistance. While IP66 protects against powerful jets of water, IP68 offers complete waterproofing and can withstand submersion beyond 1 meter for extended periods. Ultimately, choosing between the two ratings depends on the intended use and specific environmental conditions of the device.
