Legal information
Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.
CAUTION
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.
NOTICE
indicates that an unintended result or situation can occur if the corresponding information is not taken into
account.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The device/system may only be set up and used in conjunction with this documentation. Commissioning and
operation of a device/system may only be performed by qualified personnel. Within the context of the safety notes
in this documentation qualified persons are defined as persons who are authorized to commission, ground and
label devices, systems and circuits in accordance with established safety practices and standards.

SIMATIC RF640T Gen 2 1
1.1 Characteristics
The SIMATIC RF640T Gen 2 transponder is a passive (i.e. battery-free) and maintenance-
free, round-shaped data carrier. It functions based on the UHF Class 1 Gen 2 technology
and is used for saving the electronic product code (EPC) of 96 bits/240 bits. The transponder
also has a 512-bit user memory.
Fields of application are industrial asset management, RF identification of tools, containers
and metallic equipment.
The tool tag is small, smart, and rugged, suitable for industrial applications with degree of
protection IP68. It is resistant to mineral oils, lubricants and detergents.
Preferably the SIMATIC RF640T is to be mounted direct on a flat metal surface of at least
150 mm diameter where it achieves a typical sensing distance of 4 m.

1.3.2 Reading range on flat metallic carrier plates
The transponder generally has linear polarization. The polarization axis runs as shown in the
diagram below. If the tag is centrically mounted on a flat metal plate, which may either be
almost square or circular, it can be aligned in any direction since the transmitting and
receiving RF660A antennas operate with circular polarization.

1.3.3 Reading range when mounted on non-metallic carriers
The transponder is generally designed for mounting on metallic objects which provide the
conditions for the maximum reading ranges

1.3.4 Influence of conducting walls on the reading range
If there are conducting walls or restrictions in the vicinity that could shade the radio field, a
distance of approx. 10 cm is recommended between the transponder and the wall In
principle, walls have least influence if the polarization axis is orthogonal to the conducting
wall.
Reading range: One conducting wall

1.3.5 Directional radiation pattern of the transponder
Preferably, align the tag parallel to the transmitting antenna. If, however, the tag including
the metallic carrier plate is tilted, the reading range will be reduced.
