IP Protection class
The IP protection type code describes the protection of a casing or enclosure against the invasion of solid foreign bodies, against the contact with dangerous parts and against the intrusion of water. The different types of influences are divided into individual IP classes.
The maximum durability, the resilience, and the eligible application field of products are thus made comparable for the user. In addition to water, dust counts as a foreign object.
Because of powerful convection blower, high dust constants can be reached, which in turn, ensures accurate test results.
Solid particle protection
5 - Dust protected: Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment.
6 - Dust tight: No ingress of dust at a negative pressure of 20 mbar inside the housing.
