Functional principle

The UHF read/write heads form a transmission zone, the size of which may vary depending on the combination of read/write head and

tag used.

The read/write distances only represent standard values measured under laboratory conditions, free from any influences caused by surrounding materials.

Attainable distances may vary 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!

Due to the higher energy needs of the

transponder for a write operation, the range

is reduced to approximately 40–60 % of the

reading range.
