FXR.4030.A Antenna NFC 13.56MHz flex adhesive Contact Pads for Mobile devices, Wearable Smart Devices, Payment Terminals, Device tracking and ID systems

This compact flexible NFC (Near Field Communications) antenna is designed for high-performance two-way read/write operation at 13.56MHz. Its low-profile flexible construction and adhesive backing help simplify integration into space-constrained devices.

• 13.56MHz NFC operation: Optimized for short-range communication use cases such as identification and access interactions.
• Flexible, low-profile format: Suitable for integration inside plastic device enclosures or placement on internal components.
• Adhesive-backed mounting: Enables fast placement during assembly.
• Integration-friendly termination: Plated contact pads support straightforward connection to host electronics using suitable contacts (e.g., pogo pins or spring clips).
• Ferrite-layer variants available: Options are available to help reduce performance losses when the antenna is placed near batteries or other conductive components.

Typical applications

• Mobile devices
• Wearable Smart Devices
• Payment Terminals
• Device tracking and ID systems
• Access Control
