COMPONENT PROTECTED FROM DUST (IP5X)
A dust protected component has an enclosure in which the ingress of dust is not completely prevented. In order to be classifiable with the IP5X degree, a component must guarantee good functioning even in the event of minimal dust infiltration. In the case of the IP5X rating test, further checks are necessary to ensure that the product functions correctly despite the infiltration of dust.
DUST-TIGHT COMPONENT (IP6X)
A fully dust-tight enclosure ensures that there is no dust inside and in this case the components can be classified with IP6X degree of protection. Unlike the IP5X dust tightness test, the IP6X test does not require any additional assessment as the presence of dust in the enclosure is considered unacceptable.
