IP rating

Ingress Protection (IP) is a measure of protection for devices against water and particles. The first digit of the code states the device's protection against particles. The second digit states the protection against water.

First digit of code: Protection against solid foreign objects

0:  No particular protection

1:  Large solid foreign bodies ≥ 50 mm in diameter (back of the hand)

2:  Medium-sized solid foreign bodies ≥ 12 mm in diameter (fingers)

3:  Small solid foreign bodies ≥ 2.5 mm in diameter (some tools, wires)

4:  Granular foreign bodies ≥ 1 mm in diameter (tools, small wires)

5:  Harmful accumulations of dust — dust protection. Penetration of dust is not entirely preventable, but must not penetrate in such quantities that operation is affected. Complete contact protection.

6:  All penetration of dust — dust proof. Complete contact protection.

Second digit of code: Protection against water

0:  No particular protection

1:  Water falling vertically (water drip)

2:  Water sprays up to 15° from vertical (oblique water drip)

3:  Water sprays up to 60° from vertical (water spray)

4:  Water splashing from any direction (water splash) Limited ingress is permitted, but must not affect operation

5:  Jets of water from any direction (water spray) Limited ingress is permitted, but must not affect operation

6:  Strong jets of water from any direction (flooding) Limited ingress is permitted, but must not affect operation

7:  Immersion between 15 cm and 1 m (dipping)

8:  Permanent immersion under conditions defined by the manufacturer (immersion)

9:  Ingress of water from any direction, even high pressure or steam cleaning
