Application Note        

1  IP Rating Definition 

 
IP ratings are a classification used to express the degree of protection from dust and 
water penetration into the housing. 

• 

IP stands for Ingress Protection  

• 

The rating’s first digit e.g. IP66 relates to the ingress protection against dust (6 
means dust tight, see the table below)  

• 

The second digit e.g. IP66 relates to the ingress protection against water (6 
means protected against heavy water jets, see the table below)
