EXPLANATION OF IP PROTECTION CLASS
1. An IP rating only reflects protection from solid objects and water.
It does not describe general weather resistance, such as protection from UV radiation and
temperature, etc.
2. The first identification digit indicates protection from dust, solid objects and contact:
IP2X Protected against solid foreign bodies ≥ 12.5 mm in diameter
IP3X Protected against solid foreign bodies ≥ 2.5 mm in diameter
IP4X Protected against solid foreign bodies ≥ 1.0 mm in diameter
IP5X Protected against dust in harmful quantities and completely protected against
contact
IP6X Are dust-tight and completely protected against contact
3. The second identification digit indicates protection from water:
IPX0 No protection
IPX1 Protection against dripping water
IPX2 Protection against dripping water when the device is tilted up to 15°
IPX3 Protection against falling spray water up to 60° from the vertical
IPX4 Protection against splashing water on all sides
IPX5 Protection against water jets (nozzle) from any angle
IPX6 Protection against strong water jets
IPX7 Protection against temporary immersion
4. In addition, some device-specific measures such as covers and sealing caps are necessary in
order to achieve the specified protection class (e.g. protective caps on unused connections).
The IP rating of the product can be found in the technical data and is printed on the
device.
