25 Years of Excellence in
Protective Case Manufacturing

All KeXin protective cases meet the IP67 protection rating, which means:
1. Complete dust ingress protection (Level 6);
2. Can withstand immersion in 1 meter of water for 30 minutes (Level 7).
Our cases are suitable for outdoor exploration, marine environments, industrial sites, desert conditions, and other harsh environments, providing reliable protection for your equipment.

To choose the right case, follow these steps:
1. Measure your equipment: Length x Width x Height, precise to the millimeter;
2. Allow buffer space: We recommend reserving 20-30mm on each side for foam cushioning;
3. Check product specifications: Each product page provides detailed external dimensions, internal dimensions, and volume data;
4. Consider accessories: If you need to store cables, chargers, or other accessories, add extra space accordingly.
You can also contact our technical team directly — just provide your equipment dimensions and we will recommend the most suitable model.
