The degaussing device of the acousto-magnetic anti-theft device is mainly used to invalidate the anti-theft soft tag during the cashier operation of various shopping malls, so as to avoid the customer's misunderstanding caused by the anti-theft tag triggering the alarm when the customer passes the acousto-magnetic anti-theft detection system. However, how should the performance and effect of degaussing equipment be evaluated so that merchants can make correct judgments when purchasing degaussing equipment?
▲we need to know what the key technical indicators of degaussing equipment are.
1. Degaussing range
One of the key indicators to measure the degaussing device of the acousto-magnetic anti-theft device is the effective degaussing range of the degaussing device, which is usually expressed as the large and reliable degaussing distance between the acousto-magnetic soft tag and the surface of the degaussing device. From a practical and convenient point of view, the degaussing range should cover the entire working surface of the degaussing device, and all directions of the soft label should be considered. The demagnetization distance of soft labels is generally not less than 10 cm.
For some degaussing equipment, according to the degaussing reminder signal they send out, the degaussing distance is relatively large. However, the acousto-magnetic soft tags have not been completely demagnetized and are still active. The second degaussing must be performed at a height closer to the degaussing equipment. Therefore, when evaluating the degaussing range of the degaussing device of acousto-magnetic anti-theft device, we must pay attention to the reliable degaussing range, which should not be confused by the so-called large degaussing height.
2. Degaussing speed
It is usually measured by the number of reliable degaussing per minute. The degaussing speed is an indicator used to check the length of time that the degaussing device continues to be charged to saturation and fully discharged. It determines the continuous degaussing ability of the degaussing device of the acousto-magnetic anti-theft device. The slow degaussing speed affects the work efficiency of the cashier. Some degaussing machines seem to be faster, but they cannot degauss reliably and require repeated degaussing, which actually affects the efficiency of the cashier's work.
▲we need to understand the basic degaussing function of the degaussing device of the acousto-magnetic anti-theft device. What value-added functions are there to help businesses prevent theft?
The more important value-added function of the degaussing device of the acousto-magnetic anti-theft device is the "anti-theft function". The degaussing device has the characteristics of integrated linkage with the mainstream barcode laser scanner in the market. In normal cashier operations, cashiers usually must ensure that the laser scanner correctly scans the barcodes of the goods, and at the same time or afterwards, degauss the anti-theft soft tags. Some cashiers and employees often use direct demagnetization instead of scanning product barcodes to kill anti-theft soft tags to steal products.
The degaussing device with anti-theft function starts the degaussing action only after receiving the degaussing trigger signal output by the barcode laser scanner that has been scanned correctly. Any cashier's attempt to degauss the anti-theft system by "skip scanning" the product barcode will not succeed.
This function has a very effective anti-theft and anti-damage effect to reduce the conspiracy to steal goods by employees in and outside the store.
▲ we need to understand green degaussing equipment.
Any electronic product has electromagnetic radiation, and degaussers have larger electromagnetic radiation. Beyond a certain distance, its radiation is within a safe range. In order to reduce electromagnetic radiation as much as possible, "green" use of degaussing equipment is often ignored by most companies.
The degaussing device of the acousto-magnetic anti-theft device with the function of "preventing internal theft" starts degaussing and generates electromagnetic radiation only when the product is correctly scanned and the acousto-magnetic anti-theft tag is within the detection range of the degaussing device. In addition, the degaussing equipment is in a "sleep" state, with low energy consumption. Therefore, the degaussing device for acousto-magnetic anti-theft device with this function is environmentally friendly.
