The IP code is a system which is used in Europe to determine the compactness for electronic devices. The code helps us to determine degree of protection provided against intrusion such as dust and water. The content of the code is presented in the IEC 60529 standard.
The label consists of the IP (Ingress Protection) text as well as from two numbers and optional letter markings.
The first number tells the protection against outside objects and dust. The larger the number the more compact the device.0: No protection.
The second number tells the protection against water and humidity. The larger the number the better the resistance against humidity
|The second number tells the protection against water and humidity|
