flex_rfid03 Magnetic flux convergence is improved by increasing relative permeability (μ') while keeping the magnetic loss (μ") low. Prevents interference between a loop antenna and metallic objects, and effectively improves communication range of RFID. (Effective carrier frequency: 13.56MHz and below) Type RM4 is halogen free composition, considering environmental load.
