PREMO launches a 3D-coil with double functionality in both Low Frequency (125kHz) and high frequency applications (13.56MHz). All in one package. In the last few years, communication technology by NFC has experienced a lot of improvements. New tablets, smart phones, etc, has been announced with this NFC functionality for E-Wallet application.
Besides it, the high security level for data transmission that low frequency offers, makes think that the suitable solution should be one component in which both communication techniques are feasible. The 2D1D15 series, provides 2D orthogonal coils designed for working at low frequency (standard 125kHz) and a third orthogonal coil with this low frequency 2D which works at high frequency (standard 13.56MHz).
This innovative and extremely compact antenna has a high surface resistance NiZn ferrite core material (>10MΩ/mm) and medium initial permeability to work at high and low frequency. This provide a very stable performance in a wide range of temperature (-40 to +85ºC). The 2D1D15 series, has the same format as 3DC15 (125kHz) transponder family and they can be provide with same mechanical performance: label, cap and/or foam.
The 2D1D15 series is offered with 4.77mH at 125kHz and 6uH at 13.56MHz as standard inductance values. This antenna can be ordered with custom inductance parameters to fit the desired performance. Its SMD configuration allows an easy integration in an automatic PCB assembly process (lead-free reflow), avoiding handling of the piece that could damage winding wire of the piece.
The 2D1D15 series meets the AEC-Q-200, one of the most restrictive quality standards for electric components in automotive applications. This implies a guarantee and security in the performance of the component in applications for both domestic and industrial environments.
The inductance and “Q” factor of the NFC coil has been measured at 13.56MHz and are suitable for RFID applications with ISO15693 (vicinity: I-CODE) and ISO 14443 (proximity: MIFARE) interface.
