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 data carrier.

The read/write distances mentioned here only represent standard values measured under

laboratory conditions.

The read/write distances of the data carriers

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 read/write on-the-fly!
