Degree of protection against water, human body and solid foreign material.
Protection degree is specified as per IEC (International Electrotechnical Commission).
|
First figure | Description | |
---|---|---|
0 | No protection | |
1 | Protection against contact with internal live parts by a human hand (ø50 mm ø1.969 in) | |
2 | Protection against contact with internal live parts by a human finger (ø12 mm ø0.472 in) | |
3 | Protection against contact with internal live parts by a solid object more than 2.5 mm 0.098 in in thickness or diameter | |
4 | Protection against contact with internal live parts by a solid object more than 1.0 mm 0.039 in in thickness or diameter | |
5 | Protection against dust penetration which can affect operation | |
6 | Complete protection against dust penetration |
Second figure | Description | |
---|---|---|
0 | No protection | |
1 | No harmful effect due to vertically falling water drops | |
2 | No harmful effect due to water drops falling from a range 15° wider than the vertical | |
3 | No harmful effect due to water drops falling from a range 60° wider than the vertical | |
4 | No harmful effect due to water splashes from any direction | |
5 | No harmful effect due to direct water jet from any direction | |
6 | No water penetration due to direct water jet from any direction | |
7 | No water penetration due to immersion in water under specified conditions | |
8 | No water penetration during immersion, even under conditions that are more harsh than the ones in No.7 |
Note : | The IEC standard prescribes test procedures for each protection degree given above. The protection degree specified in the product specifications has been decided according to these tests. |

Although the protection degree is specified for the sensor including the cable, the cable end is not waterproof, and is not covered by the protection specified. Hence, make sure that water does not seep in from the cable end. |
This specifies protection against oil in addition to IP67 / IP68 protection of IEC standards. It specifies that oil drops or bubbles should not enter from any direction.
