Reading Distance Test Results

The following table provides the reading distance test results for the PN5321 Mini NFC module using different antenna configurations with ferrite:

Antenna Type Square Mifare S50 (85x54mm) Round Mifare S50 (25mm diameter)
40x50mm Antenna with Ferrite 5.8 cm 3.3 cm
10x25mm Antenna with Ferrite 3.0 cm 2.0 cm

Ferrite reduces electromagnetic interference, resulting in clearer signal reception and transmission.

This video will show you the difference between normal antenna and Ferrite antenna.

Applications

Ideal for use in IoT devices, smart wearables, consumer electronics, access control systems, and healthcare devices.
