How to understand the waterproof and dustproof level of barcode scanner

1.Dustproof Level

No  object size

effect

0        / Unable to protect barcode scanner from contact object invasion
1 Prevent objects larger than 50mm to enter Large surfaces of any item, such as the back of the hand cannot enter, but do not prevent intentional contact with the body parts.
2 Prevent objects larger than 12mm to enter Prevent fingers or similarly sized objects to enter
3 Prevent objects larger than 2.5mm to enter Prevent tools, thick wires, etc. to enter
4 Prevent objects larger than 1.0mm to enter Prevent most wires and screws to enter
5 Dustproof It does not completely prevent dust to enter, but it must be in sufficient quantity to affect the normal operation of the equipment and completely prevent object contact.
6 Dustproof Dust cannot enter and completely prevents objects from coming into contact.

2.Waterproof Level

No Waterproof level Definition
0        / Unable to prevent liquid to enter
1 Prevent dripping water to enter Vertical water droplets should have no adverse effects.
2 Prevent tilting 15° drip into When tilting to 15° of the normal attitude, vertical water droplets should have no adverse effects.
3 Prevent the spray to enter Water mist within 60° above the equipment should have no adverse effects on the equipment.
4 Prevent splashing water to enter Water should splash from any angle onto the equipment without adverse effects.
5 Prevent low pressure water column to enter The water column ejected from the nozzle (6.3mm) should be sprayed from any angle onto the equipment casing without adverse effects.
6 Prevent high pressure water column to enter The water column ejected from the powerful nozzle (12.5mm) should be sprayed from any angle onto the equipment casing without adverse effects.
7 Can be immersed in water up to 1m The equipment enclosure will not be damaged by water immersion when immersed in water (up to 1m) under specified conditions, including water pressure and time.
8 Can be immersed in water up more than 1m The equipment is suitable for immersion in water for long periods of time under the conditions specified by the manufacturer. Usually this means that the device is sealed. However, on some devices, it can also mean that water can enter without causing negative effects.
