In recent days, China has been subjected to the test of rainfall, and Beijing, Shenzhen, Tianjin, and other cities have suffered different levels of floods. In the post-disaster relief, we discovered that due to the influence of the typhoon, this led to a very severe test for LED outdoor screens that were exposed to heavy rain, typhoons, and first-line reports that displayed instant messages. After the pain of the disaster, the editors believe that customers who purchase LED outdoor displays in the future will be more likely to consider the display's ability to sustain continuous operations under extreme circumstances, so as to avoid irreversible losses.
The main rating criteria for the sealing performance of waterproof connectors is based on the IP Waterproof rating standard. To see how waterproof connector waterproof performance, mainly look at the two digits behind the IPXX XX, the first X is from 0 to 6, the highest level is 6; the second X is from 0 to 8, the highest level is 8; so waterproof The connector has a maximum waterproof rating of IP68.
Specific reference standards are as follows:
First, the degree of protection of solid objects (the first X)
0: No protection 1: Prevent the penetration of solids above 50mm, which is equivalent to the length of one hand;
2: Prevents 12.5mm solid intrusion; equivalent to the length of a finger;
3: Prevent 2.5mm from entering the intrusion. Equivalent to a line or tool;
4: Prevent the entry of solids larger than 1.0mm, equivalent to a line or peeling line;
5: prevent dust entering the full damage 6: completely prevent dust entering <br> <br> Second, the degree of protection of water (second X indicates)
0: Not waterproof 1: Preventing water drops 2: When the housing is tilted to 15 degrees, water droplets drip into the housing No effect 3: Water or rain does not affect from the 60 degree corner to the housing 4: Liquid splashes into the housing in any direction without harm Impact 5: Flush with water without any harm 6: Prevent strong jets of water, can be used in the cabin environment 7: Can withstand flooding in a short time 8: Continued flooding under a certain pressure From the above level can be seen that IP68 is The highest degree of protection means that the IP68's display can be continuously flooded under a certain pressure and completely prevent the entry of dust. However, the protection level of LED display is also divided. In general, the protection level in front of the LED display is relatively high, and the rear panel will be lower.
