The sensitivity of a barcode scanner is mainly affected by several key factors. The following is a detailed explanation and summary of these factors:

Scanning distance (depth of field): Barcode scanners have different scanning distances, depending on their type and technology.

The working distance of 2D image barcode scanners is generally limited to 0-750px, but the newly produced ones have extended the depth of field to more than 2500px.

The user needs to understand the scanning distance of the device and scan within its working range.

Scanning angle: The scanning angle is another important factor affecting the sensitivity of the barcode scanner.

When using, the barcode must be scanned directly in accordance with the standard method to obtain the best results.

Scanning the code at an angle will result in insensitive performance, so it is crucial to maintain the correct scanning angle.

Barcode characteristics: The size, contrast, damage or distortion of the barcode will affect the sensitivity of the scanning device.

The barcode needs to be of moderate size. Too small or too large may affect recognition.

The contrast of the barcode should be obvious enough, and the color of the bar should be darker than the color of the space.

The barcode should be kept straight and avoid being stained, damaged, twisted or excessively bent.

Scanning time interval setting: You can improve the scanning sensitivity of the barcode scanner by setting the scanning time interval.

Reasonable time interval setting helps the device better capture and recognize barcode information.

To enhance the sensing sensitivity of the barcode scanner, the user needs to understand the scanning distance and angle range of the device and ensure that the scanning is performed within the correct range and angle. At the same time, the characteristics of the barcode will also affect the recognition ability of the device, so it is also important to keep the barcode clear, complete and in the correct direction.
