RFID Heads and Tags

RFID tags are information carriers, e.g. on a transport container or an object. They store data that can be changed according to the process step. The RFID read/write heads that transmit the information have to be reliable and easily integrated. With our broad portfolio of RFID tags and RFID read/write heads in different frequency ranges and designs, we can offer you the right RFID solution for every industrial identification application.

RFID read/write heads are available as near and far field components. They are controlled by control units and read out read-only codes and variable data areas from RFID tags. They can also write to the data areas.

• RFID read/write heads from Pepperl+Fuchs are easy to integrate, for instance as a slim cylinder with an external thread in a flat or compact housing.
• For near field RFID (inductive 125 kHz and 13.56 MHz), the read/write distances lie in the one- to two-figure centimeter range
• For far field RFID (868 MHz), the read/write distances reach a maximum of six meters

In terms of RFID tags, you can select between code carriers, which contain an individual code, and data carriers, which can be read and written to. Along with variable information, data carriers always store a read-only code that ensures reliable identification. We supply RFID tags in a wide variety of designs, including flat cylinders, shell forms, and in credit card format. Fastening options include press-fitting, external thread, flange and fixing holes

• Robust, thermally and chemically resistant transponders for the low-frequency near field RFID LF (inductive 125 kHz) are insensitive to electromagnetic interference, can be built directly into metal, and are cost-efficient
• With the high-frequency near field RFID HF (inductive 13.56 MHz), you can work three to four times faster than with low-frequency technology. These RFID tags are very flat, and flexible to integrate due to a coil with just a few windings
• Tags for the UHF far field RFID (868 MHz) can be either active or passive. Passive tags are very inexpensive to manufacture and can be attached easily to a wide variety of objects
