Good to know: What are IP protection classes?

IP protection classes at a glance

The letters "IP" in the IP protection class stand for "Ingress Protection" or "International Protection". They indicate the degree of protection of electrical devices against the ingress of solid foreign bodies (first digit) and moisture (second digit). "Ingress Protection" shows how well a device protects against external influences, and "International Protection" indicates that these standards are recognized and standardized worldwide. Together, the letters represent the global standards for describing the degree of protection of electronic devices.  

The first digit of the IP classification refers to protection against solid foreign bodies. For example, a '0' means no protection, while a '5' indicates dust protection and a '6' dust-tightness. From large particles to fine dust, these digits provide a clear overview of how well the appliance is protected against the ingress of solids.

The second digit indicates how well the device is protected against moisture. Here the scale ranges from '0' for no protection to '8' for protection against permanent immersion under special conditions. Whether it is dripping water, splashing water or even temporary submersion - these figures provide clear orientation.

A protection class for every application

IP protection classes have a direct impact on the possible uses of electronic devices. An IP44 classification, for example, means protection against solid foreign objects with a diameter of one millimeter or more and protection against splashing water. This protection class could be ideal for use in environments where moisture and small particles play a role, for example in workshops.

For more robust requirements, however, you could look for devices with higher IP classifications. An IP65-certified device, for example, is not only protected against dust, but also against water jets from any angle. This makes it suitable for outdoor use where it may be exposed to severe weather conditions.

Selecting the right IP protection class

Choosing the right IP protection class is crucial for the longevity and performance of electronic devices. It ensures that a device can withstand the specific requirements of its environment, whether in a dusty workshop, a damp outdoor area or an underground system. It is therefore equally important for developers, manufacturers and end users to understand the IP classification and take it into account when selecting electronic devices.

Keywords such as IP protection class are not uncommon in our product portfolio either; the SQUARE 18, SQUARE 21 and our RUGGED Tab 10, for example, are IP 65 dust and water-protected. What's more, our RUGGED Tab 10 is even MIL-STD-810G certified. This certification is a US military standard that defines the suitability of equipment for use in military applications.
