What is the difference between IP67 and IP68

In the world of technology, especially in the realm of smart devices and gadgets, you may often come across terms like IP67 and IP68. These are two standards that define the level of protection an electronic device has against dust and water. In this article, we will explore the differences between IP67 and IP68 and understand what sets them apart from each other.

Understanding IP Ratings

Before discussing the specific differences between IP67 and IP68, it is essential to have a clear understanding of what IP ratings represent. IP stands for Ingress Protection or International Protection, and it is followed by two digits. The first digit represents the level of protection against solids such as dust, while the second digit indicates the degree of safeguarding against liquids like water. Now, let's dive deeper into each rating individually to comprehend their dissimilarities.

IP67: Solid and Liquid Resistant

IP67 rating means that a device is entirely protected against particles like dust and sand. The number 6 signifies the highest level of solid resistance, indicating that no dust can enter the device under any circumstance. The second digit, 7, denotes the device's ability to withstand water immersion. A device with an IP67 rating can be submerged in water up to 1 meter deep for a maximum duration of 30 minutes. However, it is worth mentioning that the IP67 rating does not guarantee complete protection against water pressure or diving into water at various depths.

IP68: Enhanced Waterproofing

Moving on to IP68, this rating offers an additional layer of protection compared to IP67. Similar to IP67, IP68 devices are fully sealed against dust and other solid particles. However, the second digit i.e., 8, indicates an increased ability to resist water immersion. A device with an IP68 rating can be submerged in water over 1 meter deep for a more extended period, usually specified by manufacturers. This rating implies that IP68 devices are not only suitable for accidental spills or short-term water exposure but also designed to withstand continuous submersion under specific conditions.

Conclusion

To summarize, the main difference between IP67 and IP68 lies in their respective water resistance capabilities. While both ratings provide excellent protection against dust and solid debris, IP68 takes it a step further in terms of water resistance. If you frequently find yourself using your electronic devices near water bodies or have concerns about accidental water damage, investing in an IP68-rated device is a wise choice. However, it's crucial to remember that no device is completely impervious to water damage, and the longevity of waterproofing may vary based on usage patterns and manufacturer specifications.
