Degree of Protection

First symbol: Degree of protection against solid materials

Degree	Protection
0		No protection
1		Protects against penetration of any solid object such as a hand that is 50 mm or more in diameter.
2		Protects against penetration of any solid object that is 12.5 mm or more in diameter. Protects against any solid object such as a finger that is 12 mm in diameter from reaching a hazardous location even if the solid object penetrates up to 80 mm.
3		Protects against penetration of any solid object such as a wire that is 2.5 mm or more is diameter.
4		Protects against penetration of any solid object such as a wire that is 1 mm or more in diameter.
5		Protects against penetration of dust of a quantity that may malfunction the protect or obstruct the safetyoperation 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	Not protected against water.	No test
1	Protection against water drops	Protects against vertical drops of water towards the product.	Water is dropped vertically towards the product from the test machine for 10 min.
2	Protection against water drops	Protects against drops of water approaching at a maximum angle of 15° to the left, right, back, and front of vertical towards the product.	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 sprinkled water approaching at a maximum angle of 60° from vertical towards the product.	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 water spray approaching at any angle towards the product.	Water is sprayed at any angle towards the product for 10 min from the test machine.
5	Protection against water jet spray	Protects against water jet spray approaching at any angle towards the product.	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 highpressure water jet spray approaching at any angle towards the product.	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	Resists the penetration of water when the product is placed underwater at 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	Can be used continuously underwater.	The test method is determined by the manufacturer and user.

• *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

[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.

[Note]

• Oil resistance is confirmed using oils and cutting oils stipulated by OMRON (equivalent to previous JEM standards).
