Germany’s Wuerth Elecktronik’s new EMBItag is smaller and more rugged than most other tags currently available in the market, reports RFID Journal. The new tags can be integrated into components, assemblies or containers.
The EMBItag could track products and assets in such places as highly metallic manufacturing sites, oil and gas drilling sites, or other locations where temperatures reach extreme levels. According to the company, the transponders can be incorporated into an injection-molded plastic object, for example, making it a fixed part of a product.
An NXP Semiconductor’s passive high-frequency (HF) or ultrahigh-frequency (UHF) RFID chip, as well as a metallic antenna, are embedded by the company into a plastic housing to make the inlay rugged for industrial use.
According to the company, the process involves connecting an RFID chip to the antenna, with the antenna’s design based on the dimensions of the tag needed. The joined chip and antenna are then embedded into thermosetting epoxy material, thereby creating a protective coating.
The tags are 0.83 millimeter thick, and can vary in length and width from 6 x 6 millimeters to 50 x 15 millimeters.
“We don’t see the standard EMBItags as our main focus,” Heldmaier states. “The specific option to build up even a small quantity of special tags with a chip the customer wants and an antenna layout fitting best to the working area—that is the benefit.”
Currently customers are testing the new tag, and are carrying out pilot projects to determine whether RFID tags can be built into products or tools, or be otherwise utilized within harsh environments.
