What is meant by IP ratings?

thumb FT22 outside 90 group WetIP (also known as Ingress Protection) rating is an international standard (IEC 60529) that measures how effectively devices/products are protected from intrusion by foreign solid objects or liquids.

The IP Rating uses two numbers to determine a device/products ingress protection rating. Each number is rated on a scale of zero to eight. The first digit determines the protection rating against solids and the second digit determines the protection against liquids. Sometimes you will see a rating of "X" which means no rating.

Breakdown of the IP (Ingress Protection) digits can be seen below.
