Range When Mounted On Flat Metallic Carrier Plates; Range When Mounted On Non-Metallic Carrier Materials - Siemens SIMATIC RF600 System Manual

7.12.3.2

Range when mounted on flat metallic carrier plates

The transponder generally has linear polarization. The polarization axis runs as shown in the
diagram below. If the transponder is centrally mounted on a plane metal plate, which may
either be almost square or circular, it can be aligned in any direction if the transmitting and
receiving antennas operate with circular polarization (such as the RF660A).
Figure 7-35
To achieve the listed maximum ranges, the transponder must be mounted on a metallic
mounting surface with a minimum diameter of 150 mm.
On rectangular carrier plates, the range depends on the mounting orientation of the
transponder.
You will find more information on the range in the section "Minimum distances and maximum
ranges (Page 55)".

Range when mounted on non-metallic carrier materials

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 300 mm.
You will find more information on the range in the section "Minimum distances and maximum
ranges (Page 55)".
