Is the IP protection level of the bar code scanning gun as high as possible?

Is the IP protection level of the bar code scanning gun as high as possible?

When buying a bar code scanning gun, you will see the term "IP grade" in the product introduction. What is the meaning of "IP grade"? Does it mean that the larger the value, the better?

What is the IP protection level of the barcode scanning gun?

IP is the abbreviation of the English name ingress protection, that is, the protection level. Its standard is drafted by IEC to classify electrical equipment and other equipment according to their dust-proof and waterproof characteristics.

The IP protection level is composed of two numbers. The marking rule is IP + ab. the first marked number a indicates the level of dust prevention and foreign invasion prevention of the electrical appliance, and the second marked number B indicates the degree of tightness of the electrical appliance against moisture and water invasion. The larger the number, the higher the protection level.

Specific reference standards are as follows:

1、 Dust proof and foreign object prevention level (first marked number)

0 no protection there is no special protection for external people or objects.

1 prevent solid foreign objects larger than 50mm from invading; Prevent the human body (such as the palm) from accidentally contacting the internal parts of the electric appliance, and prevent foreign objects with large size (diameter greater than 50mm) from invading.

2 prevent solid foreign objects larger than 12.5mm from invading; Prevent people's fingers from contacting the parts inside the electric appliance, and prevent medium-sized (diameter greater than 12.5mm) foreign objects from invading.

3 prevent solid foreign objects larger than 2.5mm from invading; Prevent tools, wires and similar small foreign objects with diameter or thickness greater than 2.5mm from invading and contacting the parts inside the electric appliance.

4 prevent solid foreign objects larger than 1.0mm from invading; Prevent tools, wires and similar small foreign objects with diameter or thickness greater than 1.0mm from invading and contacting the parts inside the electric appliance.

5 completely prevent the invasion of foreign objects. Although it can not completely prevent the invasion of dust, the amount of dust will not affect the normal operation of the electric appliance.

6 completely prevent foreign objects and dust from invading.

2、 Waterproof grade (second marked number)

0 no protection no special protection against water and moisture.

1 prevent water droplets from invading; Vertically falling water drops (such as condensed water) will not cause damage to electrical appliances;

2 when the inclination is 15 degrees, the water drop can still be prevented from invading. When the electrical appliance is inclined from vertical to 15 degrees, the water drop will not cause damage to the electrical appliance.

3 prevent the water sprayed from invading; Prevent rain or damage caused by water sprayed in the direction with an angle less than 60 degrees from the vertical.

4 prevent splashed water from invading; Prevent water splashed from all directions from intruding into the electric appliance and causing damage.

5 prevent the water from entering; To prevent the water ejected from the nozzles in all directions from intruding into the electric appliance and causing damage.

6. Prevent the intrusion of big waves; The electrical appliances installed on the deck can prevent damage caused by strong waves.

7. Prevent water intrusion during immersion; If the electric appliance is immersed in water for a certain time or the water pressure is below a certain standard, it can ensure that it will not be damaged due to water intrusion.

8 prevent water intrusion during sinking; The electric appliance will sink indefinitely under the specified water pressure to ensure that it will not be damaged due to water intrusion.

After the above description, we should have a comprehensive understanding of the IP level of the barcode scanner, and it will also play a positive role in selecting the barcode scanner in the future. However, do not blindly choose products with high IP level. After all, the higher the level, the more expensive the price will be.
