Degree of Protection

[Note]
  • degrees of protection given in this document were confirmed by OMRON based on the test conditions given below.
    Confirm satisfactory sealing performance in the actual operating environment and under the actual operating conditions before use.

IEC (International Electrotechnical Commission)
Standards (IEC 60529 2001)

First symbol: Degree of protection against solid materials

Degree Protection
0 No protection against dust or dirt
1 Protects against total penetration of any round object that is 50 mm in diameter.
2 Protects against total penetration of any round object that is 12.5 mm in diameter.
3 Protects against any penetration of any round object that is 2.5 mm in diameter.
4 Protects against any penetration of any object that is 1.0 mm in diameter.
5 Protects against penetration of dust or dirt of a quantity that may cause the product to malfunction or interfere with the safety operation of the product.
6 Protects against penetration of all dust.

Second symbol: Degree of protection against water

Degree Protection Test method (with pure water)
0 No protection No protection against water entry. No test
1 Protection against water drops
Protects against any harmful effects of vertical drops of water. Water is dropped vertically towards the product from the test machine for 10 min.
2 Protection against water drops
Protects against any harmful effects of drops of water approaching the product at a maximum angle of 15° off vertical. Water is dropped for 2.5 min each (i.e., 10 min in total) towards the product inclined 15° to the left, right, back, and front from the test machine.
3 Protection against sprinkled water
Protects against any harmful effects of water spray striking the product at a maximum angle of 60° off vertical. Water is sprinkled at a maximum ngle of 60° to the left and right from vertical for 10 min from the test machine.
4 Protection against water spray
Protects against any harmful effects of water spray striking the product at any angle. Water is sprayed at any angle towards the product for 10 min from the test machine.
5 Protection against water jet spray
Protects against any harmful effects of water jet spray striking the product at any angle. Water is jet sprayed at any angle towards the product for 1 min per square meter for at least 3 min in total from the test machine.
6 Protection against high-pressure water jet spray
Protects against any harmful effects of strong water jet spray striking the product at any angle. Water is jet sprayed at any angle towards the product for 1 min per square meter for at least 3 min in total from the test machine.
7 Protection underwater
Protects against any harmful effects from the penetration of water when the product is placed underwater at a specified pressure for a specified time. The product is placed 1 m deep in water (if the product is 850 mm max. in height) for 30 min.
8 Protection underwater
Protects against any harmful effects from the penetration of water when the product is placed continuously underwater under conditions individually agreed to by the manufacturer and user (stricter than for degree 7). The conditions are determined between the manufacturer and the user of the product.
  • *1:OMRON Test Methods
    The Proximity Sensor's IP67 degree of protection was confirmed by performing the tests described in the table below and making sure that the sensing distance and installation resistance satisfied the performance specifications after repeating a heat shock cycle 5 times, consisting of immersing the Sensor in cold water at 0°C for 1 hour followed by hot water at 70°C for 1 hour.
  • *2:Precautions on OMRON Testing
    Operating conditions for E2F Proximity Sensors: Underwater within 10 m
    • (1)No penetration of water when immersed in water for 1 hour at an atmospheric pressure of 2
    • (2)Satisfies sensing distance and insulation resistance performance specifications after the heat shock cycle described in *1 is repeated 20 times

IP69K Degree of Protection

IP69K is a standard for protection again ingress of high-temperature, high-pressure water defined in the German standard DIN 40050 Part 9. The test piece is sprayed with water at 80° at 80 to 100 bars with a nozzle of the specified shape. The water volume is 14 to 16 l/min. The test piece is separated from the nozzle by 10 to 15 cm and water is sprayed for 30 s each at 0°, 30°, 60°, and 90° while the test piece is rotated on a horizontal plane.

[Note]
  • If the connections section is not wired correctly, or if connectors without sufficient protection or e-CON connectors are used, the degree of protection given in the ratings may not be achieved for the connections section.

Oil Resistance

Degree of protection
Oilproof No harmful effect when subjected to oil drops or oil spraying from any direction.
Oil-resistant No penetration into internal parts when subjected to oil drops or oil spraying from any direction.
[Note]
  • Oil resistance is confirmed using oils and cutting oils stipulated by OMRON (equivalent to previous JEM 1030 standard).
