IP66 Enclosures

IP66 enclosures offer waterproof protection for your electronic and electrical components in indoor and outdoor applications. Durable IP66 cases and junction boxes are available in a variety of sizes and styles. Material options for IP66 enclosures include plastic, steel, and aluminum. Meeting IP66 ratings ensures components and devices stay protected in dusty, dirty and wet environments. IP66 rated boxes are designed for use in a wide range of industries such as oil and gas, alternative energy, marine, telecommunications and more.

Polycase IP Ratings are based on the NEMA 250 to IEC 60529 conversion table published by NEMA.org.

What Are the Features of an IP66 Enclosure?

IP66 enclosures are weatherproof outdoor enclosures with the following protective features:

  • Dust-tight protection for maximum performance against flying dust, dirt, debris, and other particulates
  • A high degree of protection against water ingress, including all types of precipitation as well as hose-directed washdowns

IP66 enclosures are as versatile as they are tough, and they’re rated for either indoor or outdoor use, making them a go-to choice for commercial and industrial enclosures of all kinds. See our IP66 enclosure guide for more about this rating, or read our IP rating guide to learn more about the IP system.
