IP protection



The IP classification according to EN 60529 describes how the encoder is protected against particles and water. It is described as an abbreviation ”IP” followed by two numbers.
These two tables summarise the most used IP ratings.

Protection against particles (first digit)
The higher the number the smaller the particles.
Protection against water (second digit)
The higher the number, the higher the water pressure can be.
