Working principle of milk powder EAS safer

The milk powder EAS safer is an electronic security device used to prevent the theft of goods such as milk powder. It is usually used in retail environments to prevent unauthorized goods from leaving the store through electronic monitoring. The working principle and main components of the EAS safer are as follows:

Working principle

Electronic tag: The milk powder EAS system usually includes an electronic tag, which is attached to the packaging of milk powder. The electronic tag contains a small electronic chip and an induction coil.

Induction coil: The induction coil in the electronic tag is used to receive and respond to signals from the security system. The coil can be passive (no battery required) or active (requires a battery).

Monitoring system: A set of monitoring antennas are installed at the entrance and exit of the store, which are capable of transmitting and receiving electromagnetic signals. Usually, the monitoring system includes a transmitter and a receiver to form an electronic "access control" area.

Signal detection: When the electronic tag passes through the access control area of the monitoring system, the induction coil interacts with the signal emitted by the transmitter. If the tag is valid (registered and authorized), it will be recognized and allowed to pass. If the tag is not authorized or unlocked correctly, the monitoring system will trigger an alarm.

Alarm system: If an unauthorized tag is detected passing through the access control area, the system will sound an audible or visual alarm to alert the store clerk or security personnel to check.

Main components

Electronic tags: Usually attached to the goods, containing electronic chips and induction coils.

Transmitters and receivers: Installed at the entrance or exit of the store, used to transmit and receive signals.

Control unit: Central equipment that manages and controls the entire EAS system, processes alarm information and system settings.

Alarm device: A device that emits an audible or visual signal when an unauthorized tag is detected.

Specific adjustment steps

Installation and calibration: Install the transmitter and receiver of the monitoring system at the door and calibrate to ensure accurate signal coverage and detection.

Label attachment: Attach the electronic tag to the packaging of the milk powder to ensure that the tag is firmly attached to the product.

System testing: Test the system's responsiveness by simulating the situation of the tag passing through the access control area to ensure that the alarm system can work correctly.

Daily maintenance: Regularly check and maintain the monitoring system to ensure it is functioning properly and handle possible failures or false alarms.

Through these steps, the milk powder EAS safer can effectively prevent product theft while reducing disruption to store operations.
