What IP rating do you need?

IP (Ingress Protection) rating 
The IP rating refers to the level of protection that is provided, with lower numbers offering minimal protection, and higher numbers offering maximum protection in accordance with BS EN & IEC 60529 standards. The first digit refers to the level of protection from solids such as dust and debris. The second digit refers to protection against moisture intrusion. In some cases, an additional letter may be applied to the end of an IP code. For example, IP69K, where 9K denotes close range high pressure, high temperature water jets.

The Ingress Protection

Many applications require electrical and electronic equipment to work safely and reliably for many years under difficult environmental conditions. The ingress protection classification DIN EN 60529 supports protection against accidental contact and foreign bodies, as well as protection against moisture. The IP categories specify the extent to which the surface of the enclosure is closed and is protected from dust and water. The letters IP (ingress protection) is followed by a two-digit number.

The first digit indicates the level of protection against accidental contact and foreign bodies:

Digit Protection against accidental contact Protection against foreign bodies
0 No protection No protection
1 Protection against large-area bodies Ø 50 mm Large foreign bodies (Ø 50 mm and higher)
2 Finger protection (Ø 12 mm) Medium-sized foreign bodies (Ø 12.5 mm and higher, up to 80 mm in length)
3 Tools and wires (Ø 2.5 mm and higher) Small foreign bodies (Ø 2.5 mm and higher)
4 Tools and wires (Ø 1 mm and higher) Granular foreign bodies (Ø 1 mm and higher)
5 (K) Wire protection (same as IP 4) dust-protected Dust deposits
6 (K) Wire protection (same as IP 4) dust-proof No entry of dust

 

Typically IPX4 is splash proof, IPX7 is ok for temporary submersion down to 1m for 30mins, and IPX8 is ok for continuous submersion as specified by the manufacturer.

The second digit indicates the level of protection against water:

Digit Protection against water
0 No protection
1 Protection against water dripping vertically
2 Protection against water dripping vertically when the enclosure is inclined at an angle of up to 15°
3 Protection against water spraying onto the enclosure onto the enclosure at up to 60° on both sides of the vertical
4 Protection against splash water from all sides
4k Protection against splash water from all sides at increased pressure, applies only to road vehicles
5 Protection against water jets (nozzle) from any direction
6 Protection against powerful water jets (flooding)
6K Protection against powerful water jets at increased pressure (flooding), applies only to road vehicles
7 Protection against temporary immersion – Immersion depth: 1 meter, test time 30 minutes
8 Protection against constant immersion – agreed between manufacturer and customer
9K Protection against water during high-pressure/steam jet cleaning, applies only to road vehicles
