Features

■The tags must undergo adequate stress

tests within the proposed temperature

processes before deployment.

■The following stress test was performed on

this tag:

Cyclic temperature stress: 5 min at -40 °C –

5 min at 90 °C

Number of tested cycles: 100, transition

period: 30 seconds

Continuous load: 140 °C for 100 hours

■This successfully performed test does not

imply suitability for a specific application,

but merely serves as proof of the basic

usability.

■FRAM memory 2 kB

■Not for direct mounting on metal

Functional principle

The HF read/write devices 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 tags suitable for

mounting in/on metal were determined in/on

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!
