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 digit indicates protection from dust, solid objects and contact:
IP2X
Protected against solid foreign objects ≥ 12.5 mm in diameter
IP3X
Protected against solid foreign objects ≥ 2.5 mm in diameter
IP4X
Protected against solid foreign objects ≥ 1.0 mm in diameter
IP5X
Protected against dust in harmful quantities and completely protected against contact
IP6X
Dust-tight and completely protected against contact
3. The second digit indicates protection from water:
IPX0
No protection
IPX1
Protection against dripping water
IPX2
Protection against dripping water when the device is tilted by 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, certain device-specific measures such as covers and sealing caps may be 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 specifications and is printed on the
device.
