Now you have the ONTIME FC series ferrite coil either in 58 KHz or 8.2MHz, put it in your hand, See how light it is? Just 3 grams. See how thin it is? As thinner as 2 mm. It could be easily fitted into any of your safer cases, or it could ultimately help to reduce the thickness and weight of your hard tags.

Performance are unique:

• The 58KHz Ferrite coil is 1.3-1.5m in detection by ULTRAPOST, it can stand for any duration in between the sensor without being killed.
• The 8.2MHz Ferrite coil is 1.3-1.8m in detection upon the system's support, its improved inner-structure keeps it from being detuned by metal.
