Check out our guide to understanding all your options when it comes to outdoor enclosures, or read more below for a quick-start primer on choosing a weatherproof enclosure that’s right for your application.

What to Look For in an Outdoor Enclosure

The most important features of an outdoor enclosure typically include some combination of the following:

  • Resistance to harsh conditions such as wet weather, windblown particles, UV radiation, and/or corrosion
  • NEMA and/or IP rated for reliable protection against environmental hazards
  • Protective attributes such as a waterproof silicone gasket
  • Made from sturdy materials like stainless steel, polycarbonate, or aluminum
  • Features such as wall mount flanges or pole mount kits for secure attachment
  • Options for customization include adding cutouts or graphics printed on the enclosure

Since outdoor conditions can vary widely by application, it’s important to first consider the expected conditions your enclosure will need to withstand. Our outdoor enclosure guide will help you examine the relevant factors and make the best choice for your application.
