How to choose a demagnetizer for acousto-magnetic anti-theft equipment?

The degaussing device of the acousto-magnetic anti-theft device is mainly used in the cashier operation of various types of optional shopping malls to make the anti-theft soft label invalid, so as to avoid the customer's misunderstanding caused by the active anti-theft label triggering the alarm when the customer passes the acousto-magnetic anti-theft detection system. However, how to evaluate the function and function of degaussers, so that businesses can make correct judgments when purchasing degaussers? First of all, we need to understand the key technical objectives of degaussers.

Degaussing range

One of the key objectives to measure the degaussing device of acousto-magnetic anti-theft equipment is the effective degaussing range of the degaussing device, which is usually expressed as the maximum reliable degaussing distance on the surface of the acousto-magnetic soft label spacer degaussing device. From the convenience of practical application, this degaussing range should cover the entire working surface of the degaussing device, and can take into account all orientations of the soft label. Usually, the maximum degaussing interval of soft labels shall not be less than 10cm.

For some degaussers, according to the degaussing prompt signal they announce, the maximum degaussing interval is still relatively large. However, the acousto-magnetic soft label has not been completely degaussed and is still in an active state. It is necessary to be closer to the height of the degaussing device. Perform the second degaussing. Therefore, when we evaluate the degaussing range of acousto-magnetic anti-theft equipment degaussing equipment, we must pay attention to a reliable degaussing range, and cannot be confused by the so-called maximum degaussing height.

Demagnetization speed

Usually measured in the number of reliable degauss per minute. The degaussing speed is the objective of checking the length of time that the degausser is continuously charged to saturation and fully discharged. It determines the continuous degaussing ability of acousto-magnetic anti-theft device degaussers. The degaussing speed is slow, which affects the cashier's cashier power. Some demagnetizers seem to be faster, but they cannot be demagnetized reliably and require repeated demagnetization, which actually affects the work efficiency of the cashier.

Secondly, we need to understand the basic functions of degaussing of the acousto-magnetic anti-theft equipment degaussing device, what value-added functions are there to help the merchant's product anti-theft?

The important value-added function of acousto-magnetic anti-theft device degausser is "anti-theft function". This degausser has the characteristics of integrated linkage operation with the mainstream barcode laser scanner in the market. When the cashier is in the normal cash register operation, it is usually necessary to ensure that the laser scanner correctly scans the barcode of the product, and at the same time or later, the degaussing operation of the anti-theft soft label is performed. Some cheating cashiers and employees often use degaussing and killing the anti-theft soft label without scanning the product barcode to achieve the purpose of stealing the product.

The degaussing device with anti-theft function can only start the degaussing action after receiving the correctly scanned degaussing trigger signal output by the barcode laser scanner. Any attempt by a cashier to "miss scan" of a product's barcode in an attempt to degauss the anti-theft system will fail. This function has a very useful product anti-theft and loss prevention effect on reducing the internal and external collusion of store employees to steal products.

We need to know that any electronic product has electromagnetic radiation, and degaussers have relatively large electromagnetic radiation. After a certain interval, its radiation is within the safe range. Minimize electromagnetic radiation as much as possible, "green" use of degaussers is often ignored by most businesses. The acousto-magnetic anti-theft device degausser with "anti-internal theft function" will only start the degaussing action when the product is correctly scanned and there is an acousto-magnetic anti-theft label within the detection range of the degaussing device to generate electromagnetic radiation. , the degaussers are in a "sleep" state, and their own energy consumption is low. Therefore, the acousto-magnetic anti-theft device degausser with this function is green and environmentally friendly.
