All About IP Codes …
So not to get disturbed with this jargon of numbers…
IP Codes (International Protection or Ingress Protection ) marking refers to the degree of protection provided against intruding forces (body parts such as hands and fingers), dust, contact by accident, and intrusion of water by fabricated casings and electrical enclosures. It is issued by the International Electrotechnical Commission (IEC) and European standard iEN 60529.
The primary purpose of this code is to supply more accurate information than often common marketing terms such as “Dust proof/ waterproof”.
First Number: Solids
It indicates the degree of protection that the product’s enclosure provides against the intrusion of solid objects, including certain human body parts such as hands and fingers, as well as dust and accidental contact, etc.
The first digit of the index starts at 0, indicating that there is no particular protection; and ends at 6, indicating that the product is completely protected against the intrusion of any dust.
Second Number: Liquids
It indicates the equipment’s degree of protection against water penetration and humidity.
The second digit of the protection index starts at 0, meaning that there is no protection against water or humidity; and ends at 8, specifying that the product can withstand being completely submerged for a long period of time.
In the case of an Enclosure that is IP65-certified, such as the outdoor Rack Enclosures, this means the Enclosure is protected against dust, that there will be no intrusion that there will be no intrusion of foreign matter for 2 to 8 hours
Also from Rain water or Jet sprays, though limited ingress is allowed.
Thus, when understanding the outdoor application for enclosures episodes such as a rain or duststroms, it will be essential to install an IP65 Enclosurethat is resistant to dust and to strong jets of water.
We can evaluate and select the IP classification that indicates the level of protection required for our application.
