Protection against contact and penetration of water and dirt
Computers and monitors often have to work reliably for many years in difficult environmental conditions. Dirt, germs, bacteria, dust and moisture can only rarely be kept out completely.
In addition, it is almost impossible to avoid improper contact with foreign bodies or other objects, particularly in the operating theater.
The IP ratings specify the extent to which an electrical component can be exposed to environmental influences without being damaged or constituting a safety hazard.
In medically sensitive areas, an appropriate IP rating guarantees appropriate IP protection for both the equipment and the patient, as the equipment can safely be cleaned with standard hospital disinfectants.
