A two-digit number established by the International Electro Technical Commission, is used to provide an Ingress Protection rating to a piece of electronic equipment or to an enclosure for electronic equipment.
The protection class after EN60529 are indicated by short symbols that consist of the two code letters IP and a code numeral for the amount of the protection.
Example: IP65 (NEMA 4)
The two digits represent different forms of environmental influence:
• The first digit represents protection against ingress of solid objects.
• The second digit represents protection against ingress of liquids.
The larger the value of each digit, the greater the protection. As an example, a product rated IP54 would be better protected against environmental factors than another similar product rated as IP42.
IP TABLE:
| IP.. |
First digit: Ingress of solid objects |
Second digit: Ingress of liquids |
|---|---|---|
| 0 | No protection | No protection |
| 1 | Protected against solid objects over 50mm e.g. hands, large tools. | Protected against vertically falling drops of water or condensation. |
| 2 | Protected against solid objects over 12.5mm e.g. hands, large tools. | Protected against falling drops of water, if the case is disposed up to 15 from vertical. |
| 3 | Protected against solid objects over 2.5mm e.g. wire, small tools. | Protected against sprays of water from any direction, even if the case is disposed up to 60from vertical. |
| 4 | Protected against solid objects over 1.0mm e.g. wires. | Protected against splash water from any direction. |
| 5 |
Limited protection against dust ingress. (no harmful deposit) |
Protected against low pressure water jets from any direction. Limited ingress permitted. |
| 6 | Totally protected against dust ingress. | Protected against high pressure water jets from any direction. Limited ingress permitted. |
| 7 | N/A | Protected against short periods of immersion in water. |
| 8 | N/A | Protected against long, durable periods of immersion in water. |
| 9k | N/A | Protected against close-range high pressure, high temperature spray downs. |
IP protection of the PIP:
A PIP in the standard PIP housing is generally IP51 protected. Higher IP protection level with the standard PIP housing (up to IP54) can be reached with good positioning / orientation of the PIP. In other special PIP-housings, like a MIL-housing up to IP67 protection is possible.
IP protection of the PANEL-PIP:
The PANEL-PIP is available in various housings. Those allow a protection level of up to all around IP65.
