The second number, 5, means that water from low pressure injection is prevented from entering.

The second number, 7 means that it can be immersed in water for a short time.

Rain protection is to put the product outdoors, not afraid of raining and affecting the product. Normal work; waterproof products can be put into the water and can work normally, this is the difference.
