Innovative RFID Hardware

Choosing the right RFID hardware is key to ensuring the success of your applications. Turck offers a range of solutions to meet those needs. Let our experts help you select the ideal hardware from our portfolio of RFID solutions.

Comparing LF, HF, UHF RFID

To accommodate various application requirements, RFID operates at diverse frequencies, including low, high and ultra-high. The frequency implemented will determine the distance in which RFID tags can be read, how many tags can be read at one time, how fast these tags are read, the actual size of the tag and how the application environment will impact its performance.

Low Frequency RFID

125 – 134 kHz. Least impacted by its surroundings. Unable to read/write tags over a long distance and are limited to a single tag in the field.

High Frequency RFID

13.56 MHz. Can read/write tags over longer distances. It can read more than one tag in the field, however it is better suited for single tag applications.

Ultra-High Frequency RFID

433, and 860 – 960 MHz. Offers fast speeds, which enables it to quickly identify objects in the field and offers long-range read/write capabilities.

Read/Write Heads

There are a wide variety of Turck read/write heads to choose from.

Read/Write Head Variations

RFID Interface Blocks with I/O

Turck’s compact Ethernet RFID interfaces are based on its proven block I/O families. These solutions ensure that data can be seamlessly integrated directly into PLCs or upper level communication systems. They can also simplify implementation by eliminating extra programming effort or function blocks, using CODESYS or ARGEE. The multiprotocol devices use data from HF or UHF read/write heads for control via PROFINET, Ethernet/IP™ or Modbus TCP. They are rated up to IP69K for rugged environments.

RFID Tags

There are many types of tags, including active, passive and semi-passive (battery assisted passive). There are also hundreds of styles and form factors. Tags carry specific product data that has been pre-programmed onto a microchip. An RFID reader sends a signal out via radio waves which is then received by the tags within its range. The tags then send a signal back to the reader, which then captures all the product data. Tags can be affixed to a pallet, box of goods, an individual item such as a car body, or on a high-value asset like a die.
