Transponder
Function
As the antenna passes over the transpon-
der, it energizes the latter with an energy
field of 13.56 MHz. The transponder returns
its code through frequency modulation to
the antenna. A normal reading cycle, in-
cluding all security checks, is approximate-
ly 1 ms.
The system's operability is guaranteed
through fluid, gaseous as well as solid met-
al-free materials. However, if mounted di-
Dimensions and Specifications
The maximum reading distance for all tran-
sponders can only be achieved when the
minimum distance to the metal surface is
maintained.
It is recomended to maintain the minimum
distance within the metal-free area (figure
below). The impact on positioning accuracy
and range also depends on the size and the
distance of metal parts.
As a rule of thumb it can be said that if the
metal-free area behind the transponder has
to be at least of the same range as the read-
ing distance between transponder and an-
tenna. The reception of the transponder
signal will be largely unattenuated (see ta-
ble on right). It is essential, that the tran-

The Read-Write Transponders are
equipped with an EEPROM in
which the code is stored. The EE-
PROM may be rewritten up to more
than 100,000 times. It has 32 bit
available for user data.
sponder does not dip into the mesh/loop
of steel reinforcement grids. Single metal
rods, on the other hand, hardly have any in-
fluence on the performence.
