IP Ratings (Ingress Protection)
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.
Ingress of solid objects
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.
