RFID / NFC Absorber: IMRFS Series

High permeability absorber, engineered for both RFID range Improvement and EMI noise reduction.

  • IMRFS works to improve the range of RFID (13.56MHz) via the reduction of RFID-to-metal interference.
  • The material consists of high permeability fillers in an elastomeric matrix, making it suitable for EMI noise attenuation.
  • Applications other than RFID-improvement include: Suppression of radiated emissions in the near-field, reduction of surface noise on shield or other metal surfaces, reduction of cross-talk or other undesired coupling.
