What does IP67 mean for a robot?

IP67 means complete dust-tightness and protection against temporary immersion – usually tested at a water depth of one metre for 30 minutes.

The first digit stands for protection against foreign objects, the second for protection against water. IP67 is therefore suitable for outdoor use in rain and for dusty environments.

Important: IP67 is not an approval for hazardous areas. This confusion is widespread and has real consequences in procurement – see guide to explosion protection.
