Our transponder coils are widely used in RFID and immobilizer systems. We primarily manufacture coils for low frequency (LF) 125kHz and 134.2kHz, as well as high frequency (HF) 13.56MHz applications. We can adjust the inductance and capacitance to perfectly match your specific IC chips.
They are extensively used in automotive key fobs (immobilizers), animal tracking tags (glass tube tags), access control systems, TPMS (Tire Pressure Monitoring Systems), and various IoT tracking devices.
Yes. We use high-quality copper wire and durable core materials (such as ferrite). Our coils can be encapsulated, overmolded, or coated to withstand extreme temperatures, moisture, and mechanical shocks, meeting automotive-grade standards.
We are flexible to support your business from R&D to mass production. For most transponder coils, our MOQ is highly negotiable. Small trial orders are welcome for your initial testing phase.
