SMARTRAC On Metal RFID Wet Inlay (Monza 4QT)

SMARTRAC’s On Metal RFID Wet Inlay is designed for tagging metal objects and surfaces, as well as challenging non-metal objects. The thin, soft and flexible tag structure ideally suits curved and flat surfaces, and offers converters huge opportunities to create attractive solutions for end users.

This printable, On Metal RFID Wet Inlay enables applications that were not possible earlier with traditional UHF inlays, and offers the possibility to easily print and encode the product with standard RFID printers on-site. It delivers excellent performance on metal surfaces and liquid-filled bottles with a read-range of up to 3.5 meters. Furthermore, the tag features traceable and secure TID serialization. It is available in ETSI (for Europe) and FCC (for America and Asia) frequency bands. SMARTRAC’s design and manufacturing expertise developed the thinnest On Metal Tag, at 600µm ± 10 %, which not only protects the print heads of RFID printers, but also ensures optimum converting properties and usability. The product is delivered in wet format as a single-row at 500-unit reel with reliable adhesion for demanding surfaces. A clean gap between the tags makes it user-friendly.
