REQUIREMENTS
The following characteristics apply under following conditions:
8.1 Temperature
8.1.1 Communicators
In most applications, normal convection cooling is enough. In applications where heat is
generated close to the Reader, forced cooling or heat shields may be necessary.
The S1566 has the following characteristics: Environmental temperature: -25 to +60
°
C.
8.1.2 Tags
TagMaster Tags are available for operation in various ambient temperatures ranging from -40
°
C
up to 85
°
C, refer to the data sheets. The specified reading range is valid for normal ambient
temperature conditions. If reading range is critical and the intended operating temperature
deviates from normal ambient temperature TagMaster AB should be consulted.
8.2 Supply
Voltage
The Reader is supplied with external DC to the connector (pin P=12 V and pin R=0 V (return)).
