Ingress Protection—Classifying the Degrees of Protection

Posted on 3/12/18 1:00 PM

Dust, dirt, water—all “enemies” of electronic products due to the potential damage they can cause. To help address this issue, the International Electrotechnical Commission (IEC) has created a classification system (IEC 60529) designating degrees of protection regarding enclosures of electrical equipment against the invasion of contaminants, such as dust, dirt, or moisture, plus other foreign bodies (e.g. tools or fingers).
