IP Ratings Explained

The IP rating of equipment is mentioned many times in the sales literature that you might read. It is typically shown as IP54 or IP67 etc.

An IP rating is a two-digit number established by the International Electro Technical Commission and is used to provide an Ingress Protection rating to a piece of electronic equipment or to an enclosure for electronic equipment.

The first number is the object protection level; the second number is the moisture resistance level. The numbers range from 1-8 with 8 meaning better protection. In radio we only really see 4-8 mentioned.

So, the higher the numbers you see, the better the protection level.
