Micro Embedded PCB FR4 UHF RFID Tag (Dia 4.5 x 4.1 mm) - P-MD4.5

The Micro Embedded PCB FR4 UHF RFID Tag (Model P-MD4.5) is an ultra-compact, high-durability passive RFID transponder engineered for covert asset tagging, precision tool tracking, and anti-tamper IT security. Measuring just 4.5 mm in diameter and 4.1 mm in height, it is among the smallest on-metal UHF tags available globally, making it ideal for embedding directly into metallic cavities, tool sockets, medical instruments, and laptop chassis where standard tags cannot fit.

1. Covert Secondary Tagging for Laptop Anti-Theft

In enterprise IT asset protection systems, this micro tag functions as the hidden secondary audit tag. While a primary on-metal tag is mounted on the laptop chassis for long-range gate detection, the P-MD4.5 tag is embedded deep inside the internal motherboard cavity or internal frame. If an unauthorized individual attempts to remove or grind off the exterior tag, the internal P-MD4.5 tag remains intact, exposing the physical tamper attempt during security portal scans.

2. High-Performance On-Metal RF Coupling

Despite its miniature size, the P-MD4.5 utilizes the high-sensitivity NXP UCODE 8 (U8) silicon IC. Engineered with tuned FR4 substrate dielectric layers, the tag leverages the surrounding metallic body as an extended ground plane, achieving an astonishing read range of up to 1.4 meters on metal when interrogated by standard industrial fixed or handheld RFID readers.

3. Rugged Industrial Construction & Extreme Thermal Tolerance

Encapsulated with high-grade black industrial epoxy resin, the P-MD4.5 delivers complete IP68 environmental protection:

• Operating Temperature: -30°C to +85°C
• Ambient Thermal Resistance: -30°C to +180°C (withstands high-heat electronic operating environments and industrial sterilization cycles)
• Chemical & Oil Resistance: Fully resistant to cutting fluids, machine oils, cleaning solvents, and moisture.

4. Installation & Mounting Options

• Press-Fit Insertion: Drill a 4.6 mm pilot hole in metallic tool handles or sockets and press-fit the tag flush with the surface.
• Structural Epoxy Potting: Secure the tag inside internal laptop chassis cavities using 2-part industrial epoxy adhesive.
• Surface Adhesion: Mount directly onto metallic brackets using high-strength cyanoacrylate or VHB adhesive.
