On-Metal RFID Tags & Labels

Metal changes the electrical environment of a tag antenna. A standard inlay placed directly on steel or aluminium can become detuned and lose its usable read response. An on-metal RFID label separates the antenna from the mounting surface using a purpose-designed structure. The foam-spacer designs in this collection are intended for direct attachment to metal, making them a practical option for equipment, cabinets, tools and IT assets where a conventional paper label cannot provide reliable RF performance.

Begin by measuring the flat area available on the asset. The label needs enough room to sit securely, and its position should support the direction from which your reader approaches. The size and shape of the metal object matter, as do nearby metal parts, covers and obstructions. A result measured on a large flat plate is a reference for comparison, not a promise that the same distance will be achieved on a small component or recessed equipment panel.

Compare the chip, footprint and total thickness in each product record. The collection includes different Monza and UCODE chip choices; they are not interchangeable specifications. Memory and sensitivity come from the chip datasheet, while the complete label needs application testing. A thin label may be easier to fit into a confined location, but choosing the thinnest option without testing can overlook the mounting surface and the RF requirements of the workflow.

Printing and EPC encoding let the visible asset number, barcode and electronic identifier follow your own numbering scheme. Specify the face artwork and the data to be written, including any locking requirement. Before a volume order, apply samples to cleaned, dry surfaces and test them with your handheld, portal or fixed reader. Check reads at the expected distance and orientation, with doors and covers in their normal positions. Share the operating environment and handling conditions so we can assess the label construction and adhesive with you.
