Industrial RFID

What is RFID (Radio Frequency Identification)?

RFID employs radio frequency communications to exchange data between a portable memory device and a host computer or PLC. An RFID system typically consists of a tag (usually in the form of a label or small printed circuit board) containing data storage, an antenna to communicate with the tag, and a controller to manage the communication between the antenna and the PC or PLC (the terms reader or reader/writer are used when the antenna and controller are combined in a single unit). Importantly, the tag is commonly attached to a product carrier, tote or even the product itself, providing a remote database that travels with the product.

UHF (Ultra High Frequency) Balluff

UHF systems feature long range, and high speed read/write rates. Small antennas and even smaller tags have proven this to be an effective frequency for tracking pallets through dock doors, as well as trucking and transportation  applications. Industrial UHF applications have also begun to effectively be developed for tracking parts, product and carriers through production.

HF (High Frequency) Balluff

HF has the advantage over other frequencies of being able to read/write to a tag in the presence of water, metal and  other obstructions. This ability has proved the HF Frequency ideal for rugged industrial environments. For industrial applications involving significant environmental obstructions HF is a preferred frequency.
