What is the difference between IP67 and IP68 ?

Ingress Protection (IP) ratings are a measure of how well an electronic device can withstand solid and liquid intrusions. The IP rating system is divided into four categories, with IP67 and IP68 being the most commonly used.

IP67: Water and Dust Resistance

IP67 rating means that the device is resistant to solid objects (such as dust and water) that are larger than 1mm in size. This means that the device can withstand exposure to normal water usage without being damaged. In addition, IP67 devices are also resistant to spraying water, which can help prevent damage from water jets.

IP68: Water and Dust Resistance

IP68 rating means that the device is resistant to both solid and liquid intrusions. This means that the device can withstand exposure to normal water usage, as well as being resistant to spraying water. IP68 devices are also resistant to dripping water and other liquid sources.

Differences between IP67 and IP68

While both IP67 and IP68 ratings are designed to protect electronic devices from solid and liquid intrusions, there are some key differences between them. The main difference is the level of protection against dust. IP67 devices are designed to withstand small solid objects, while IP68 devices are designed to withstand larger solid objects.

Conclusion

In conclusion, IP67 and IP68 ratings provide a convenient way to measure the resistance of electronic devices against solids and liquids. While both ratings are similar in many ways, IP67 devices are designed to withstand smaller solid objects, while IP68 devices are designed to withstand larger solid objects. Understanding the differences between these two ratings is important for selecting the right device for your specific needs.
