IP Rating

What is an IP rating?

IP (Ingress Protection) Rating for Equipment and Enclosures
A two-digit number (as specified in Australian Standards AS60529 and EN60529) is used to provide an IP Rating to a piece of electronic equipment or to an enclosure for electronic equipment.

The two digits represent two different forms of environmental influence:

The first digit represents protection against ingress of solid objects
The second digit represents protection against ingress of liquids

The larger the value of each digit, the greater the protection from that influence. As an example, a product rated as IP57 would be better protected against environmental factors than another similar product that was only rated as IP43. A Neptun 9000 is rated at IP68 (totally protected against dust ingress and protected against long periods of immersion under pressure).
