Is IP68 better than IP66 ?

When it comes to the waterproof rating of electronic devices, the terms IP66 and IP68 are commonly used. But what do these ratings actually mean? IP66 and IP68 are designed to protect electronic devices from dust and water, but they differ in their specific requirements and levels of protection.

IP66 rating means that the device is protected from dust that is 0.1mm or larger than the diameter of the opening of the device. Additionally, the device must also be protected from water that is splashing from all directions, including a 3m (9.8ft) water jet, and must not be able to penetrate the device.

On the other hand, IP68 rating means that the device is protected from dust that is 0.1mm or larger than the diameter of the opening of the device, as well as water that is splashing from all directions, including a 3m (9.8ft) water jet, and must not be able to penetrate the device. In addition, the device must also be protected from contact with solid objects that are larger than 1mm (0.04in) in diameter.

It is important to note that IP66 does not imply that the device is protected from all forms of water, such as, IP68 does.

Comparing IP66 and IP68

So, is IP68 better than IP66? The answer may vary depending on the specific requirements of the device and the environment in which it will be used. However, in general, IP68 provides more comprehensive protection against water and dust compared to IP66.

IP68 is designed to provide protection against water that is splashing from all directions, including a 3m (9.8ft) water jet, as well as dust that is 0.1mm or larger than the diameter of the opening of the device. In addition, IP68 is designed to provide protection against contact with solid objects that are larger than 1mm (0.04in) in diameter.

In conclusion, IP68 is a more comprehensive rating than IP66, and provides better protection against water and dust. However, it is important to carefully consider the specific requirements and environment of the device before choosing an IP rating.
