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.

1.3.4 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

1.3.6 Use of the transponder in hazardous areas
TÜV NORD CERT GmbH, appointed center no. 0044 as per Article 9 of the Directive
94/9/EC of the European Council of 23 March 1994, has confirmed the compliance with the
essential health and safety requirements relating to the design and construction of
equipment and protective systems intended for use in hazardous areas as per Annex II of
the Directive.
The essential health and safety requirements are satisfied in accordance with standards
EN 60079-0:2004, EN 50020:2002, IEC 61241-0:2004 and IEC 61241-11:2005.

1.3.7 Use of the transponder in hazardous areas for gases
Temperature class delineation for gases
The temperature class of the transponder for hazardous areas depends on the ambient
temperature range:
Ambient temperature range Temperature class
-25 °C to +85 °C T3
-25 °C to +60 °C T4
-25 °C to +40 °C T5
-25 °C to +30 °C T6
WARNING
Ignitions of gas-air mixtures
When using the RF640T transponder, check to ensure that the temperature class is
observed in respect of the requirements of the area of application
Non-compliance with the permitted temperature ranges while using the transponder can
lead to ignitions of gas-air mixtures.
WARNING
Ignitions of gas-air mixtures
The maximum transmitting power of the transmitter used to operate the transponder must
not exceed 2 W.
Non-compliance with the permissible transmitting power can lead to ignitions of gas-air
mixtures.

1.3.8 Use of the transponder in hazardous areas for dusts
The equipment is suitable for dusts whose ignition temperatures for a dust layer of 5 mm are
higher than 210 °C (smoldering temperature). With the ignition temperature specified
according to IEC 61241-0 and IEC 61241-11 according to the type of ignition protection iD,
the smoldering temperature of the dust layer is referenced in this case.
Temperature class delineation for dusts
Ambient temperature range Temperature value
-25 °C < Ta < +85 °C T140 °C
WARNING
Ignitions of dust-air mixtures
When using the RF640T transponder, check to ensure that the temperature values are
complied with in connection with the requirements of the application area.
Non-compliance with the permitted temperature ranges while using the transponder can
lead to ignitions of dust-air mixtures.

1) At temperatures above 70 °C the casing may distort slightly; this does not however cause
any impairment of function (mechanical or electrical).
2) Directive 94/9/EC of the European Council of 23 March 1994 must be complied with, see

3) The values for shock and vibration are maximum values and must not be applied
continuously.
WARNING
Ignitions of gas-air or dust-air mixtures
When using the RF640T transponder, check to ensure that the temperature values are
observed in respect of the requirements of the hazardous area of application.
Non-compliance with the permitted temperature ranges while using the transponder can
lead to ignitions of gas-air or dust-air mixtures.
NOTICE
Damage to the surface of the housing
The values specified for the IP x9K test are maximum values and must not be applied
continuously.
Protracted loading of the transponder can lead to damage to the surface of the housing due
to high pressures.
1.6.5 Chemical resistance of the RF640T Gen 2 transponder
The following table gives an overview of the chemical composition of the data memory made
from polyamide 12. The plastic housing has a notably high resistance to chemicals used in
automobiles (e.g.: oil, grease, diesel fuel, gasoline) which are not listed separately.
