IP67 refers to the Protection safety Rating, in which IP stands for Ingress Protection Rating, which defines the protection capability of an interface against liquid and solid particles. It is a grade standard of dustproof and waterproof performance drafted by the International Electrotechnical Commission; For example, the protection level is IP67, IP - marking letters, 6 - the first marking digit, 7 - the second marking digit. The first marker number is the solid state protection level, which is the protection against people or objects from the outside, ranging from 0 to 6, and the second marker number is the liquid protection level, ranging from 0 to 8. The higher the number of both, the stronger the capability.
IP code: the protection level of the shell, the protection level of the electrical equipment shell is divided into many categories, according to different numbers, can quickly and easily determine the protection level of the product.
The first marked number indicates the contact protection and foreign object protection level (protection range 0-6), which is represented by the following numbers:
0 - No protection.
1 - Protection against solid particles with a diameter of 50mm and larger objects with tips or solid particles with a diameter of 50mm cannot be fully penetrated
2 - Protection against solid particulate matter with a diameter of 12.5mm and larger objects tip or solid particulate matter with a diameter of 12.5mm cannot be fully penetrated
3 - Protection against solid particles of 2.5mm diameter and larger object tips or solid particles of 2.5mm diameter are completely impenetrable
4 - Protection against solid particles with a diameter of 1mm and larger object tips or solid particles with a diameter of 1mm are completely impenetrable
5 - Protective dust may not completely prevent dust from entering, but the amount of dust entering will not hinder the normal operation of the device and reduce the safety of the device.
6 - Dust closure completely prevents foreign objects from invading, and can completely prevent dust from entering.
The second marked number indicates the waterproof protection level (protection range 0-8), which is represented by the following numbers:
0 - No protection.
1 - Prevent vertical falling water droplets; Water drop protection Falling water droplets should not cause damage.
2 - When the shell can be tilted up to 15° to prevent vertical falling water droplets; When the water drop cabinet is tilted at an Angle of 15 degrees to any side, the water drop falling vertically should not cause damage.
3 - Waterproof fog; Water sprayed from a 60-degree Angle on either side of the vertical line should not cause damage.
4 - waterproof; Protection from Splashing water Splashing water from each direction should not cause damage.
5 - waterproof; Water from the nozzle directed at the cabinet in each direction should not cause damage.
6 - anti-strong water spray; Protect strong jet water Strong jet water directed at the cabinet from each direction should not cause damage.
7 - Prevent short-term soaking; When immersed in water for a short time under standard pressure, ensure that no damage is caused by water.
8 - Anti-continuous soaking; Protection against long-term immersion can be immersed in water under specific conditions to ensure that no damage is caused by water.
In summary, IP67 means: it is completely dust-proof, there is no gap in the outer case, and dust cannot enter. At normal temperature, the product will not be affected within 1M deep water. The current highest level of protection is IP68.
