Use an IP67 rated enclosure when you want to be extra sure that your design will be protected from washdown and weather. Boxes that meet these ratings will protect electronics from blown dust and water ingress in aggressive weather, and they will even protect during total immersion in water to a depth of 1 meter for up to 30 minutes. Usually, immersion is not a regular feature of IP67 applications, but the rating gives added assurance of protection for critical electronic designs.
To preserve high protection, a variety of cable glands are available as accessories. We even offer IP67-rated vents that enable passive airflow to avoid condensation. These vents employ a breathable membrane that permits airflow but blocks water.
