We are good at manufacturing bobbin-less (air core) precision coils. In addition, we can also offer injection-molded coil products.
Precision Coils (Bobbin-less Coils)
Our self-coupling bobbin-less coils using copper wire enable accurate winding of over 1,000 turns. They can maintain consistent electric properties that are essential in applications requiring high precision.
Using precision coils for RFID enables operation at various frequencies ranging from low to high frequency. They are utilized in a wide range of applications such as card coil and proximity devices.
