Information

An IP rating consists of two digits:

First digit: protection against solid foreign objects / dust

First Digit	Meaning
0	No protection
1	Protected against objects 50 mm in diameter or larger
2	Protected against objects 12.5 mm in diameter or larger
3	Protected against objects 2.5 mm in diameter or larger
4	Protected against objects 1.0 mm in diameter or larger
5	Dust-protected: dust ingress is not completely prevented, but it does not interfere with normal operation
6	Dust-tight: completely protected against dust ingress

Second digit: water protection rating

Second Digit	Meaning
0	No protection
1	Protected against vertically falling water drops
2	Protected against dripping water when the enclosure is tilted by 15°
3	Protected against spraying water
4	Protected against splashing water
5	Protected against water jets
6	Protected against powerful water jets
7	Protected against temporary immersion
8	Protected against continuous immersion
9 / 9K	Protected against high-temperature, high-pressure water jets

Industry reference:

• IP65: dust-tight + protected against water jets; suitable for installation inside general construction-machinery cabs

• IP67: dust-tight + protected against temporary immersion; suitable for outdoor operations, mobile elevating work platforms, and agricultural machinery

• IP69K: protected against high-pressure hot-water cleaning; suitable for food processing, vehicle washing, and other special applications

Note: A higher IP rating is not always better. Higher ratings impose greater requirements on sealing processes and cost. Select the rating according to the actual installation location.

▶ HAIMOOO Note: HAIMOOO electronic joysticks support up to IP67 protection for their electronic components. Sealing solutions can be customized to project requirements without redesigning the entire machine.
