Which is better: IP55 or IP65?

When it comes to protecting electronic devices against dust and water, there are specific international standards that determine their level of protection. Among the most commonly used standards are IP55 and IP65. In this article, we will explore the differences between these two ratings and help you understand which one is better suited for your needs.

Understanding IP Ratings

Before diving into the comparison, let's first understand what IP ratings signify. IP stands for Ingress Protection, and it is followed by two digits. The first digit represents the level of protection against solid objects, such as dust and dirt. The second digit indicates the degree of protection against liquids, like water.

IP55 - Durable Protection

Devices with an IP55 rating offer a considerable level of protection against dust and water. The "5" in IP55 indicates strong protection against dust, meaning that the device is dust-tight. It prevents the ingress of dust particles that could potentially damage the internal components.

Regarding water protection, the "5" in IP55 signifies resistance against low-pressure water jets from all directions. This means that the device can endure direct exposure to rain, but it may not be completely waterproof, so it should not be submerged in water.

IP65 - High-level Protection

If you require a higher level of protection for your electronic devices, IP65 could be a better choice. Similar to IP55, IP65 offers excellent resistance against dust, indicated by the "6" in its rating. With an IP65-rated device, you can be confident that no harmful dust will penetrate into the device.

In terms of water resistance, IP65 takes it a step further than IP55. The "5" in IP65 still refers to protection against low-pressure water jets, but the additional "6" represents protection against powerful water jets. This means that an IP65-rated device can withstand direct water spray, making it suitable for outdoor applications even in harsh weather conditions.


In conclusion, both IP55 and IP65 ratings provide a certain level of protection against dust and water. Which rating is better depends on your specific needs and environmental conditions. If you require devices to be protected against dust and occasional rain or splashes, IP55 should suffice. However, if you need enhanced protection against dust and water, including exposure to powerful water jets, then IP65 is the recommended choice.

Remember, always check the IP rating before purchasing electronic devices to ensure they meet your requirements for dust and water resistance.
