Sensormatic 58Khz LE Labels
Sensormatic 58Khz LE Labels are a disposble label used for hard goods and gift items. LE stands for low energy. Some retailers decided that they needed a low energy option so that their employees are not exposed to such a strong magnetic field when they are cashing out customers.
These disposable labels are sold 5000 at a time.
The 58 KHz frequency is ideal to use with anything that is metal or metallic. RF frequency signals are blocked by metal items so Sensormatic uses the 58 KHz frequency so it can be used in department stores that sell a wide variety of items.
