How to choose the degaussing device of the sound and magnetic anti-theft system

The degaussing device of the acoustic magnetic anti-theft system is mainly used for the cash-removal operation of various types of self-selected shopping malls, so that the anti-theft soft tag is invalidated, and the customer's misunderstanding is caused by the active anti-theft tag triggering the alarm when the customer passes the acoustic anti-theft detection system. However, how to evaluate the performance and effect of the degaussing device, so that the merchant can make the correct judgment when purchasing the degaussing device? This article gives some suggestions from the perspective of product technology and merchant use.

First, we need to understand what key technical indicators are available for the degaussing device.

Degaussing range

One of the key indicators for measuring the degaussing of an acoustic anti-theft system is the effective degaussing range of the degaussing device, which is usually expressed as the largest reliable degaussing distance on the surface of the degaussing of the acousto-magnetic soft tag. From the point of view of practical convenience, this degaussing range should cover the entire working surface of the degaussing device, and can take into account the various orientations of the soft label. Usually the maximum degaussing distance of the soft label is not less than 10cm.

Some degaussing devices, according to the degaussing prompt signal issued by you, the maximum degaussing distance is still relatively large, but the acousto-magnetic soft label is not completely demagnetized, still in an active state, and must be at a height closer to the degaussing device. Secondary degaussing. Therefore, when evaluating the degaussing range of the degaussing system of the acoustic anti-theft system, we must pay attention to the reliable degaussing range and cannot be confused by the so-called maximum degaussing height.

Degaussing speed

It is usually measured in terms of the number of times of reliable degaussing per minute. Degaussing speed is an indicator of the length of time during which the degausser is continuously charged to saturation and completely discharged. It determines the ability of the degaussing system of the acoustic anti-theft system to degauss continuously. The degaussing speed is slow, which affects the cashier's cash register efficiency. Some degaussers seem to be faster, but they can't be demagnetized reliably, and need to be degaussed, which actually affects the cashier's work efficiency.

Secondly, we need to understand the basic functions of the degaussing of the magnetic anti-theft system degaussing device, and also have the value-added functions that help the merchant's product anti-theft.

Anti-theft function

The most important value-added function of the magnetic anti-theft system degaussing device is the “anti-piracy function”. This degaussing device has the characteristics of working in conjunction with the mainstream barcode laser scanners in the market. In the normal cashier operation, the cashier usually has to ensure that the laser scanner correctly scans the bar code of the product, and then degaussing the anti-theft soft tag. Some cheating cashiers and employees often use the non-scanning bar code to directly degauss the anti-theft soft tag to achieve the purpose of stealing goods.

A degaussing device with anti-trap function, which only starts the degaussing action after receiving the properly scanned degaussing trigger signal output by the bar code laser scanner. Any attempt by the cashier to attempt to "leak scan" the bar code of the product to try to degauss the anti-theft system will not succeed.

This function has a very effective product anti-theft and loss prevention effect on reducing the collusion between the inside and the outside of the store staff.

Finally, we need to know the green degaussing device!

Any electronic product has electromagnetic radiation, and the degausser has relatively large electromagnetic radiation. After a certain distance, the radiation is within safe limits. To minimize electromagnetic radiation, "green" uses degaussers, which are often overlooked by most businesses.

The magnetic and magnetic anti-theft system degaussing device with "anti-intrusion function" only activates the degaussing action when the sound is scanned correctly, and the electromagnetic degaussing action is activated within the detection range of the degaussing device, and electromagnetic radiation is generated. The degaussing device is in a "sleep" state, and its own energy consumption is the lowest. Therefore, the magnetic magnetic anti-theft system degaussing device with such a function is green.
