Scanning head selection: The secret to efficiency

Now in the era of data informatization and digitalization, bar code scanner is an essential tool, and the efficiency and accuracy of bar code scanner are directly related to the speed and quality of information processing. So how to choose the right scanning head becomes particularly important.

The scanning head of the two-dimensional code module needs to deal with different scenarios, so when selecting the scanning head, we should not only consider the advantages and disadvantages of its performance, but also pay attention to the needs of practical applications. For example, for remote scanning scenes, it is more appropriate to choose a barcode scanner with a large depth of field; For the case of small and dense bar codes, you need to choose a higher resolution scan head. It's important to know what you actually want and make choices based on it.

The quality of the bar code scanner can also be comprehensively judged from the three aspects of working distance, label size and bar code density. Among them, the working distance, that is, the depth of field of the bar code scanner, refers to the maximum effective interval between the scanning head and the bar code label on the premise that the scanner can read the bar code. This parameter directly determines the applicability of the scanner in different fields. For example, zero-sales and factory environments may favor the use of contact or proximity scanners, while the warehouse and transportation industries may require the ability to scan at a distance.

Then in the actual use of environmental factors can not be ignored. For example, in the case of dim light or low bar code contrast, it is appropriate to choose a high-performance scanning head. They can maintain a high recognition rate in complex environments.

In addition, price is also a factor that cannot be ignored. In the case of a limited budget, we can buy some cost-effective products, when the scanning head of medium performance is enough to meet the needs of most enterprises. Of course, these suggestions are based on a large number of experiments and practical application experience, which can provide a scientific basis for our choice.

The selection of scanning head for two-dimensional code module is not an easy task, and we make the most appropriate choice after combining the requirements of working distance, label size and barcode density in practical applications. I hope that the above sharing can help everyone in the face of a dazzling array of scanning head choices, can be more leisurely, to find the product that really suits their own.
