What is the difference between IP and IPX rating?

The IP (Ingress Protection) and IPX ratings are commonly used to determine the level of protection that electronic devices provide against solids and liquids. These ratings are important for understanding the suitability and durability of a device in various environments. While both IP and IPX ratings serve the same purpose, there are some key differences between them.

IP Rating

The IP rating, also known as the International Protection marking, is a standard defined by the International Electrotechnical Commission (IEC). It consists of two digits that indicate the degree of protection offered by a device. The first digit represents the level of protection from solid particles, such as dust, while the second digit represents the level of protection from liquids, such as water.

For example, an IP68 rating means that the device is completely protected against dust and can be submerged in water beyond 1 meter depth for a specific time period. On the other hand, an IP44 rating indicates limited protection against small objects and splashes of water.

IPX Rating

The IPX rating is an extension of the IP rating system specifically used to indicate the protection against liquids. Instead of using a second digit to represent the level of protection from solids, the "X" in IPX denotes that there is no rating for solid particle protection.

For instance, an IPX7 rating implies that the device is not protected against any solid particles but can be immersed in water up to 1 meter depth for a specified duration without any damage. Similarly, an IPX4 rating indicates protection against water splashes from any direction, but there is no specific rating for protection against solid particles.

Conclusion

In summary, the difference between IP and IPX ratings lies in how they represent the level of protection. While IP ratings provide a comprehensive of both solid particle and liquid protection, IPX ratings concentrate solely on liquid protection. It is crucial to consider both ratings when evaluating the durability and suitability of electronic devices in different environments.

Ultimately, knowing the IP and IPX ratings helps consumers make informed decisions about which devices are appropriate for specific applications, whether it be for indoor or outdoor use, water-resistant or dustproof requirements, or any other environment-related considerations.
