The key technical indicators of the acousto-magnetic anti-theft system

The degaussing equipment of the acousto-magnetic anti-theft system is mainly used to make the anti-theft soft label invalid during the cashier operation in major shopping malls, so as to avoid customer misunderstanding caused by the anti-theft label triggering the alarm when the customer passes the acoustic and magnetic anti-theft detection system. However, how should we evaluate the performance and effect of degaussing equipment, so that businesses can make correct judgments when purchasing degaussing equipment?
First of all, 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 equipment of the acousto-magnetic anti-theft system is the effective degaussing range of the degaussing device, which is usually expressed as the larger reliable degaussing distance between the acousto-magnetic soft label 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 consider all directions of the soft label. The soft label demagnetization distance is generally not less than 10 cm.
For some degaussing equipment, according to the degaussing prompt signal it sends out, the degaussing distance is long. However, the acousto-magnetic soft tags have not been completely demagnetized and are still effective. The second degaussing must be performed at a height closer to the degaussing device. Therefore, when evaluating the degaussing range of the degaussing equipment of the acousto-magnetic anti-theft system, we must pay attention to the reliable degaussing range, which cannot be confused by the so-called large degaussing height.
2. Demagnetization speed
Usually measured by the number of reliable demagnetizations per minute. Degaussing speed is a measure of the length of time that a 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 system. The slow degaussing speed affects the work efficiency of the cashier. Some demagnetizers seem to be fast, but they cannot be demagnetized reliably and need to be demagnetized repeatedly, which actually affects the work efficiency of the cashier.
Need to understand the basic degaussing function of the degaussing equipment of the acousto-magnetic anti-theft system, and what value-added functions can help businesses to prevent theft?
The more important value-added function of the degaussing device of the acousto-magnetic anti-theft system is the "anti-theft function". The degaussing equipment has the characteristics of integrated linkage with the mainstream barcode laser scanners in the market. In normal cashier operations, cashiers typically make sure that the laser scanner is correctly scanning the product barcode while degaussing the anti-theft soft label at the same time or at a later time. Some cashiers and cheating employees often use direct demagnetization instead of scanning commodity barcodes to kill anti-theft soft tags for stealing.
The degaussing device with anti-theft function will only start degaussing after receiving the degaussing trigger signal correctly scanned by the barcode laser scanner. Any cashier who tries to degauss the anti-theft system by "skip scanning" product barcodes will be unsuccessful. This function has a very effective anti-theft and loss-prevention effect on reducing the collusion of employees inside and outside the store to steal goods.
We need to understand green degaussing equipment: any electronic product has electromagnetic radiation, and the electromagnetic radiation of degaussing device is even greater. At a certain distance, its radiation is within a safe range. In order to minimize electromagnetic radiation, the "green" use of degaussing equipment is often overlooked by most businesses.
The degaussing device of the acousto-magnetic anti-theft system with "anti-internal theft" function starts to degauss and generates electromagnetic radiation only when the goods are correctly scanned and the acousto-magnetic anti-theft label is within the detection range of the degaussing device. In addition, the degaussing unit is in a "sleep" state and consumes low power. Therefore, the degaussing device of the acousto-magnetic anti-theft system with this function is environmentally friendly.
