Harsh Environment Solutions START HERE

Whether it’s extreme heat, blistering winds or toxic chemicals – electronics are more susceptible to damage when operating in harsh environments.

Engineers must account for environmental factors before designing and should choose products with proper qualifications and ratings to protect valuable equipment and personnel.

Understanding Harsh Environment Ratings

IP (Ingress Protection) ratings consist of the letters IP followed by two digits and an optional letter.

The first digit refers to the level of protection against hazardous parts and the ingress of solid foreign objects. The second digit refers to the level of protection against the ingress of water.

This standard provides engineers with more detailed information regarding the protection status of a product than vague terms like waterproof. Below is a brief table outlining some of the common IP ratings that you’ll see across our site. We do offer products with ratings not listed below.

IP RatingWater ProtectionDust Protection
IP65Water at 12.5 liters per minute through 6.3mm nozzle from any directionTotal dust ingress protection
IP66Water at 100 liters per minute through 12.5mm nozzle from any directionTotal dust ingress protection
IP67Submersion into water up to 1 meter deep for amount of time specified by manufacturer Total dust ingress protection
IP68Permanent submersion beyond 1 meter into water of depth stated by manufacturerTotal dust ingress protection
IP69KWater at 80-100MPa (megapascal) and 14-16 liters per minute from four angles while the device is rotated at 5RPM Total dust ingress protection

Learn About NEMA Ratings for Enclosures

The National Electrical Manufacturers Association (NEMA) provides a popular standard for protective enclosures. These conditions include ingress of water and foreign objects (e.g. dust or fibers), but go beyond IP code, accounting for corrosive agents and various gases and atmospheres. The table provides a brief description of each level of protection, which NEMA specifies with a NEMA Enclosure Type Number.

Indoor Nonhazardous Locations

This is a brief table outlining the NEMA ratings as related to the use of enclosures in an indoor nonhazardous location.
