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)
