IP stands for Ingress Protection. The IEC IP protection class is an important criterion for the safety protection of electrical equipment. The IP protection rating system provides a standard for the protection against dust, water and collisions in electrical equipment and packaging. The method of classification, this
The system has been approved by most European countries and was drafted by the International Electrotechnical Commission (IEC) and announced in the IPD of IED529 (BS EN 60529:1992).
The degree of protection is often expressed in IP followed by two digits, and the number is used to define the level of protection.
The first number indicates the range of equipment dust resistance, or the extent to which people are protected from harm in a sealed environment. I stands for the level of preventing the entry of solid foreign bodies, the highest level is 6;
The second number indicates the degree of waterproofing of the device. P stands for the level of preventing water ingress. The highest level is 8.
Such as motor protection class IP65, protection class IP55 and so on.
Contact Electrical Equipment Protection and Foreign Object Protection Level (First Number) Electrical Equipment Water Protection Rating (Second Number)
First number Dust protection range Second number Waterproof protection range
0 No protection - 0 No protection -
1 For solid foreign body detectors with a diameter of 50mm and larger, the diameter of the sphere is 50mm and should not be fully entered. 1 Protection against water drops Droplets dropped vertically should not cause damage.
2 Protected 12.5mm diameter and larger solid exosome detector, sphere diameter of 12.5mm, should not completely enter the 2 cabinet tilt 15 degrees, the protection of the water droplet cabinet tilt to 15 degrees to either side, the vertical drop Water droplets should not cause damage
3 Protect solid foreign body detectors with a diameter of 2.5mm and larger. The diameter of the sphere is 2.5mm and should not be fully entered. 3 Protection against splashed water. Water splashed from both sides of the vertical line at an angle of 60 degrees should not cause damage.
4 Protection against 1.0mm diameter and larger solid exosome detectors, with a ball diameter of 1.0mm, should not be fully entered. 4 Protection against water spray from each direction of the cabinet should not cause damage
5 Protecting the dust It is impossible to completely prevent dust from entering, but the amount of dust entering will not cause harm to the equipment. 5 Protecting the shooting water Shooting water from each direction to the cabinet should not cause damage.
6 Closing of dust The cabinet should not enter dust at a low pressure of 20 mbar. 6 Protection against strong jets Strong jets that aim at the cabinet from each direction should not cause damage
7 Protection against short-term flooding When the cabinet is immersed in water for a short time under standard pressure, there should not be any water that can cause damage.
8 Protection against long-term water immersion Can be immersed in water under specific conditions. It should not cause damage.
Note: The diameter of the detector should not pass through the hole of the cabinet
Understand the waterproof rating of electronic products JIS (IPX)
0 No protection
1 Anti-drip type I Vertical drop of water without harmful effects
2 Anti-Drip Type II Drops falling within 15" from the vertical direction without harmful effects
3 Rainproof type No adverse effects on rainfall in the vertical direction within 60 degrees
4 Splashproof No harmful effects from water splashes in any direction
5 Spray-proof type Directly affected by water injection in any direction without harmful effects
6 Water-resistant type Water sprayed directly in any direction will not enter the interior
7 Immersion type will not enter the interior even if immersed in water under specified conditions
8 Underwater type can be used even if it is immersed in a certain pressure for a long time.
9 Moisture proof type can still be used when the relative humidity is more than 90% humidity.
The IP level of the international industrial standard and the JIS level of the Japanese industry standard are close to each other. The level is 0 to 9 and the IP level also specifies the dust prevention. IPxx dustproof and waterproof rating
Dust level (first X indicates)
0 : No protection
1 : Prevent large solid intrusion
2 : Prevent medium-sized solids from intruding
3 : Prevents small solids from intruding
4 : Prevent solids larger than 1mm from entering
5: Prevent harmful dust accumulation
6: Prevent dust from entering completely
Waterproof rating (second X indicates)
0 : No protection
1 : Drops of water dripping into the shell have no effect
2 : When the housing is tilted to 15 degrees, water droplets drip into the housing without affecting
3 : Water or rain has no effect on the shell from the 60 degree corner
4: Liquid spilled from the shell into the shell without harm
5 : Flush with water without any damage
6 : Can be used in cabin environment
7 : Can be flooded for a short time (1m)
8 : prolonged flooding under certain pressure
Example: There is a scale or display meter labeled IP65, indicating that the product can completely prevent dust from entering and flushing with water without any harm.
The IPXX class specifies the waterproofing test.
