Mounting of several readers on metal frames or racks
Any reader mounted on metal couples part of the field to the metal frame. There is normally
no interaction as long as the minimum distance D and metal-free areas a, b are maintained.
However, interaction may take place if an iron frame is positioned unfavorably. Longer data
transfer times or sporadic error messages at the communication module are the result.

will significantly reduce the induction of stray fields on
the rack:
