Functional principle
The HF read/write heads operating at a
frequency of 13.56 MHz, form a transmission
zone the size of which (0…500 mm) varies,
depending on the combination of read/write
head and tag used.
The read/write distances mentioned here only
represent standard values measured under
laboratory conditions, free from any influences
caused by surrounding materials.
The read/write distances of the tags for
mounting in metal TW‐R**‐M(MF) were
determined in metal.
Attainable distances may vary by up to 30
% due to component tolerances, mounting
conditions, ambient conditions and material
qualities (especially when mounted in metal)
Testing of the application under real operating
conditions is therefore essential, especially
with on-the-fly reading and writing!
