Is IP68 Better than IP66?

When it comes to the waterproof rating of electronic devices, the terms IP68 and IP66 are commonly used. But what do these ratings actually mean? And, more importantly, is IP68 really better than IP66? In this article, we will delve into the technical details of both ratings to determine which one offers superior protection against water and dust.

The Difference Between IP68 and IP66

The IP in IP68 and IP66 stands for ingress protection, a standardized rating system developed by the International Electrotechnical Commission (IEC) to classify the degree of protection provided by electrical enclosures against various environmental factors.

The first digit in the IP rating represents the dust protection level, while the second digit indicates the water protection level. In both IP68 and IP66, the highest possible rating for dust protection (6) is achieved, meaning that no harmful dust can enter the device.

However, the main difference lies in the water protection level. IP68 provides a higher level of resistance to water compared to IP66. While IP66-certified devices offer protection against powerful jets of water, IP68 devices are capable of withstanding immersion in water under specific conditions.

The Water Resistance of IP68 Devices

A device with an IP68 rating means it is completely protected against dust and can be submerged in water beyond 1 meter for a specified duration without suffering any damage. The depth and duration may vary depending on the manufacturer's specifications, but generally, an IP68 device can withstand immersion up to 3 meters for 30 minutes.

This high level of water resistance makes IP68 ideal for devices that are frequently exposed to extreme environmental conditions like smartphones, smartwatches, and fitness trackers. With an IP68 rating, users can confidently use their devices in heavy rain or even take them for a swim without worrying about water damage.

When to Choose IP66?

While IP68 provides superior water resistance, there are certain scenarios where IP66 might be more suitable. For instance, if you are looking for a device that can withstand powerful jets of water but don't necessarily need it to be fully submersible, IP66 is a cost-effective choice.

Additionally, IP66 enclosures are commonly used for outdoor installations, such as security cameras, outdoor lighting, and industrial equipment. These devices need robust protection against dust and high-pressure water from hoses or cleaning processes, but prolonged submersion is not expected.

In conclusion, the choice between IP68 and IP66 depends on your specific needs. If you require maximum water resistance, especially for portable electronic devices, IP68 is the way to go. On the other hand, if you need sufficient protection against powerful jets of water and dust but don't need full immersion capability, IP66 offers an affordable option.
