Degree of Protection
The specified degree of protection indicates whether or not the device is protected against contact, penetration by solid particles of a specified size and moisture.
IP20 (DIN EN 60529): Protection against penetration by solid particles with diameters larger than 12 mm. No special protection against penetration by water.
IP40 (DIN EN 60529): Protection against penetration by solid particles with diameters larger than 1 mm. No special protection against penetration by water.
IP42 (DIN EN 60529): Protection against penetration by solid particles with diameters larger than 1 mm. Protection against dripping water falling at an inclined angle.
IP54 (DIN EN 60529): Protection against dust deposits. Full contact protection. Protection against splash-water from all directions.
IP60 (DIN EN 60529): Full contact protection for voltage conducting components. Protection against penetration by dust. No special protection against penetration by water.
IP65 (DIN EN 60529): Full contact protection for voltage conducting components, protection against penetration by dust, protection against water jet streams.
IP66 (DIN EN 60529): Full contact protection for voltage conducting components. Protection against penetration by dust. Protection against powerful water jets.
IP67 (DIN EN 60529): Full contact protection for voltage conducting components. Protection against penetration by dust. Protection against submersion in water under specified conditions: at a depth of 1 metre for a duration of 30 minutes.
IP68 (wenglor specification): Full contact protection for voltage conducting components. Protection against penetration by dust. Protection against submersion in water under specified conditions: 1 metre for a duration of 7 days.
IP69K (ISO 20653): Full contact protection for voltage conducting components. Protection against penetration by dust. Protection against water high pressure/steam jet cleaning (80–100 bar, 80 °C).
The degree of protection depends upon the utilised plug for devices with plug connectors.
In rare cases, extreme temperature fluctuations/temperature shock, even within the admissible temperature range, may result in a reduced degree of protection due to different thermal expansion coefficients of the housing materials (housing material) used. Direct exposure to sunlight may also result in damage to the housing.
