IP66 means that the product can completely prevent the penetration of external substances and dust. When subjected to severe wave impact or strong jet, the water inlet of electrical equipment can not achieve adverse effects. IP refers to the enclosure protection level of lighting, instruments and other equipment, and GB4208 specification expounds the significance of IP coding for the enclosure protection level of equipment.
The International Electrotechnical Commission has drafted a hierarchical system of intellectual property protection.
Equipment is classified according to the characteristics of dust and moisture.
Nothing here, including tools and people's fingers, can touch the live part of this equipment to prevent electric shock. The IP protection level includes two values.
The first value represents the level of dust removal and foreign body intrusion prevention.
The second value is waterproof and moisture-proof seal. The higher the value, the higher the protection level.
Grade protection standard
IP66 dustproof grade 6, can completely isolate all substances and dust, waterproof grade 6. The electronic equipment installed on the deck can protect the equipment from the influence of waves. As the core component of monitoring system, it plays an important role in many industries.
IP54 completely prevents foreign objects from contacting conductive parts or rotating parts, and prevents dust from invading, but it does not affect mechanical work, and spraying water from around will not cause any harm. IP67 fully protects foreign objects from contact with conductive parts or rotating parts to prevent powder from invading. In water with a certain pressure and depth, the invading water will not cause any harm.
IP67 is a 6-level dustproof, 7-level waterproof and 6-level waterproof test gun with a caliber of 12.5mm, which can be used normally. In the 7-level waterproof test, the article was placed at the depth of 1- 1.2 m and soaked for 30 minutes, which had no effect on the article.
GB/T 14924- 1995
Waterproof grade 1, preventing large solid particles and only preventing large solid substances from entering the equipment.
2, to prevent the penetration of medium-volume solid substances, only to prevent smaller solid particles from entering the equipment.
3, can prevent the invasion of small particles, can prevent the invasion of small particles.
4. It can prevent solid substances above 65438±0mm from entering the equipment.
5. Prevent dust from invading the equipment.
6, the highest level of dustproof device, can completely prevent the invasion of dust.
