In the last blog article, we pointed out that the difference between IP66 and IP67 is mainly reflected in the protection purpose and protection conditions.
Coincidentally, this weekend, the JRPanel factory produced the first batch of membrane switch products with upgraded IP67 waterproof technology. So today, we would like to use these products to explain the IP67 waterproof technology of JRPanel in detail.
IP67 Process Core: Peripheral Sealing Rings
After getting our IP67 product, we can see obvious collage traces from the inside and the outside, like a circle surrounding a large panel. This is the process core of IP67 products: the peripheral sealing ring structure.
How can such a structure enhance the waterproof ability of our products? Very simple, we can understand it like this:
Remove the sealing ring, and we can treat the inner layer as a normal membrane switch. Without upgrading to IP67, if this ordinary membrane switch is in direct contact with water, the internal circuit will be in direct contact with water. Products are likely to be scrapped quickly. After upgrading to IP67, we added a layer of sealing ring to the outer layer of this membrane switch as protection, which can block water outside the sealing ring when it comes into contact with water, effectively protecting the circuit from moisture intrusion.
The above is the basic waterproof principle of IP67 products. However, not all switches can be IP67 waterproof. Next, let's talk about the design requirements of IP67 for membrane switches.
According to the engineers of JRPanel, the minimum width of the sealing ring is 5mm, which requires:
1. The length and width of the membrane switch product should be greater than 5mm;
2. The cable outlet should be at least 5mm away from the edge of the membrane switch.
Therefore, if you want to use IP67 waterproof technology on your product, you need to think about whether your product meets the above 2 design requirements.
