READ WRITE HEAD FOR RF IDENTICFICATION SYSTEMS

2. Function and features

• The DTA100 read/write head reads without contact data of RFID transponders
(ID tags) that conform to the system,
• converts them into digitally coded values
• and provides them to the AS-i control level
(AS-i master, controller or host).
Application examples:
• Material flow control in production lines
• Warehouse management by the automatic detection of stored products
• Tank management, order picking or product tracking

3. Operating principle

The ID tags are operated passively, i.e. without battery. The energy required for op-
eration is supplied by the read/write head.
The physical principle of the energy transfer is based on inductive coupling. The
antenna coil integrated in the read/write head generates a magnetic field which
partly penetrates the antenna coil of the ID tag.
A voltage is generated by induction that supplies the data carrier with energy.
