Some electronic devices spend their entire lives sitting on a desk, encountering nothing worse than the occasional spilled cup of coffee or curious cat. Other devices, however, have to survive rain, snow, windblown dust and all kinds of other outdoor hazards. Chances are, if you’re designing an electronic device, you know which kind it will be.
If you fall on the outdoor side, you’re probably looking at enclosure specs and trying to figure out which kinds of ratings and specifications your ideal enclosure needs. The IP66 rating is one that you’ll frequently find on many different kinds of enclosures — including many models from Polycase. But what does it mean, and what kind of performance can you count on from an IP66 rated enclosure? Polycase’s experts are here to answer your questions.
The ingress protection or IP rating system is an enclosure rating system based on the IP code described in the international standard IEC 60529. It’s used across the world to rate enclosures on the level of protection they provide against environmental hazards.
Specifically, they’re rated in two categories: dust protection and water protection. (If you need other features such as corrosion protection, note that IP doesn’t rate other categories. You’ll need to look for another rating scale such as a NEMA rating.)
Every IP rating is a two-digit number, and each of the digits has its own significance:
The first step to finding the IP rating that you need is to look at an IP ratings chart and determine which circumstances your device is likely to encounter. Then, you can decide whether an IP66-rated electrical enclosure will give your device a sufficient degree of protection.
An IP66 rated enclosure has a rugged design and construction that’s rated for general outdoor use. An IP66-rated enclosure offers excellent performance for many environments, including:
What performance specs can you look for from an IP66 enclosure? You can count on an IP66 to provide the following:
It’s important to note that although an IP66 enclosure is waterproof against hose-directed water and falling drops of rain or snow, it’s not intended to be submerged in water. For an enclosure that’s resistant to the harmful effects of temporary or prolonged submersion, you’ll need to move up to an IP67 (temporary) or IP68 (prolonged) enclosure.
