The staff who often purchase connectors must not be unfamiliar with waterproof connectors, but if you ask you what the numbers on the waterproof level of the purchased connectors mean, I am afraid that few people can answer them accurately. What do the numbers on the IP rating of the device mean? Next, Dosin hardware and electronic engineers will come to popularize the knowledge of the waterproof IP level of the connector.

Dosin hardware and electronic engineers pointed out that the IP level is the protection level for the intrusion of foreign objects in the enclosure of electrical equipment, which is derived from the standard IEC of the International Electrotechnical Commission; the first marked number indicates the level of contact protection and foreign object protection: the second marked number indicates waterproof protection grade. Generally speaking, the degree of protection is the sealing protection of electrical equipment to prevent foreign objects (eg: tools, dust, fingers) and moist gases from entering its enclosure. Remember, a long time ago, a lot of customers asked me what those numbers on the IP rating represented. Next, Dosin engineers will explain in detail what the numbers on the connector's waterproof IP rating mean.

1. Protection level - the first number, the first number of the IP code indicates the degree of protection against human contact and moving parts, and the protection against solid foreign objects entering the equipment shell

1- Prevent larger parts of the body (such as hands) or prevent solid substances with a diameter greater than 50MM from entering

2- Prevent objects not exceeding 80MM and 12MM in diameter from entering

3- Prevent tools, wires and other objects with a diameter or thickness greater than 2.5MM from entering

4- Prevent solid matter with diameter or thickness greater than 1.0MM from entering

5- Prevent dust accumulation from affecting equipment operation

6- Completely dustproof

Second, the protection level - the second number, the first number of the IP code indicates the degree of protection of the equipment enclosure to avoid water entering in various forms (such as water droplets, spraying, immersion, etc.)

1- Prevent water from dripping vertically

2- Prevent water from dripping at an inclination of no more than 15°

3- Prevent water from being sprayed into

4- Prevent water from getting in

5- Prevent water from being injected from the nozzle

6- Prevent a large amount of seawater or water with jet pressure from entering

7- Prevent water from entering during short-time immersion

8- Protection against water entry during a complete, continuous submersion (submerge at a depth of at least 1 meter for 15 minutes)

After reading the above, you should be very clear about "what does the number on the waterproof IP rating of the connector mean".
