3M™ EMI Absorber AB5020R is a magnetic sheet for radio frequency identification applications. This product effectively solves the interference effect of tag and reader in the metal surrounding atmosphere.
Features and Benefits
High magnetic permeability at 13.56 MHz.
Consists of dark color magnetic material layer and pressure sensitive adhesive.
Absorber sheet with one side double coated adhesive tape
Used with the 13.56 MHz RFID reader and tag to be mounted directly upon highly conductive surface.
3Μ™ ΑΒ5020R is typically used for the 13.56 MHz RFID reader and tag to be mounted directly upon highly conductive surface. This might be the reader antenna surrounded by metallic body or tag mounted on conductive substrate such as gas bottles. However, it is not possible to communicate each other under this metallic atmosphere. The magnetic fluxes through the conductive surface induce eddy current within the conductor, which opposes the field responsible for their creation. It reduces the magnetic field on the surface of the conductor to such a degree that communication between reader and tag becomes no longer possible. By inserting 3Μ™ ΑΒ5020R between antenna and conductor surface it is possible to largely prevent the occurrences of the eddy currents. This makes it possible to mount the antenna on metal surface
