7.10.3.3 Range when mounted on non-metallic carrier materials
The transponder is generally designed for mounting on metallic objects which provide the
conditions for the maximum reading ranges
Table 7- 36 Range with non-metallic carriers
Carrier material
Range
Transponder on wooden carrier
approx. 60%
Transponder on plastic carrier
approx. 65 %
Transponder on plastic mineral water bottle
approx. 70%
Transponder without base approx. 50 %
The maximum range of 100% is achieved by mounting the transponder in a free space with
low reflections on a flat metal carrier with a diameter of at least 150 mm.
You will find more detailed information on the range in the section "Minimum distances and
maximum ranges (Page 337)".
7.10.3.4 Mounting in metal
It is possible to mount the transponder in metal. If there is not enough clearance to the
surrounding metal, this reduces the reading range.
