RFID and AS-i – a strong team for identification.
 
 

 
 The RFID system for ranges up to 100 mm.
  • Inductive identification system in 125 kHz technology.
  • RFID for assembly/conveying technology and handling automation.
  • Cost reduction due to quick and easy set-up.
  • Increased write/read distances.
  • High reading reliability for compact design.

Safety and cost saving in RF identification
DTA300 with increased write/read distances solves your applications in assembly/conveying technology and handling automation. DTA300 can be integrated into AS-i networks in no time and is ready for operation immediately. In addition to the lower cost for hardware, this also saves time during set-up. DTA301 supports the AS-i profile S-7.3 for analogue input slaves. DTA301 is the compact and low-cost alternative in applications that only require reading of the ID tag data. Benefit from the unique selling proposition of ifm sensors: quick and easy to mount with absolute safety.

Functions
The ID tags are mounted on the objects to be identified (tanks, goods or workpiece carriers). When they come into the detection range of the read/write heads (read/write module), the information is read at up to 0.5 m/s. The data transfer is controlled by the AS-i control level (master, controller, gateway, host). The read/ write heads are used in the AS-i network as analogue slaves according to the profile 7.4 or 7.3 with a master controlling up to 31 slaves. The transmission of energy between the passive ID tag and the read/ write head is based on the physical principle of inductive coupling with a frequency of 125 kHz. The compact read/ write head includes, in addition to the antenna, the complete evaluation and the interface to AS-i, so that the units can be directly operated in the AS-interface network and so that the transmission of data to the controller is possible.
