What exactly do the IP protection categories stand for? This question is often heard, especially in the industrial sector. For industrial environments there are clearly defined methods and standards of protection. These establish a degree of protection for a housing in regards to touch, foreign objects (dust, sand) as well as water and/or humidity.
The abbreviation IP, stands for International Protection as outlined by DIN EN 60529 and DIN 40 050. The individual degrees of protection are always displayed as a combination of the two letters IP, as well as two numbers – for example IP65. The numbers reflect the following safety standard:
The 1. number defines the protection against touch and foreign objects (dust, sand) – in our example IP65, this is done with the number 6
The 2. number defines the protection against water and/or humidity – in our example IP65, this is done with the number 5
If needed, letters can be attached – as for example with IP69K. This “K” defines the marking, especially designated for street vehicles.
Here is an accurate listing of the individual numbers and their meaning:
|1st number||Protection against touch||Protection against foreign objects (dust and sand)||2nd number||Protection against water|
|Protection against…||Protection against…|
|0||No protection||No protection||0||No protection|
|1||Touch with back of the hand||Foreign objects > 50mm diameter||1||Dripping water falling vertically|
|2||Touch with a finger||Foreign objects > 12mm diameter||2||Dripping water falling at an angle of 15° (measured from the vertical axis)|
|3||Touch with tools||Foreign objects > 2,5mm diameter||3||Water spray up to 60° (measured from the vertical axis)|
|4||Touch with wire||Foreign objects > 1mm diameter||4||Water spray from all angles|
|5||Touch with wire||Slight dust accumulation indoors (=protection from dust)||5||Water spray from all angles|
|6||Touch with wire||Dust breach (=dust proof)||6||Temporary flooding|
|7||Temporary submersion (approx. 1/2 hour up to a depth of 1m)|
|9K||Water with elevated pressure up to 100 bar (for cleaning with water jets or steam)|
Monitors and computers with a protection degree up to IP67
The Industrial Monitors and Panel PC as part of the product line Lizard by ADM Electronic are compliant with IP54 protection standard. This means, that they are protected against dust accumulation indoors as well as water spray. The products of the Taurus series are compliant with the protection degree of IP67. This means that these Industrial PC’s and Monitors are completely dust proof as well as protected from a temporary submersion in water.
