Common Types of RFID Anti-Metal Tag

In various application scenarios, RFID tags need to be attached to the surface of metal objects. However, metal objects themselves can affect RFID tags, causing signal interference. This leads to a rapid decline in the tag's performance, and it may not even be effectively read by the respective devices. To address this issue, RFID anti-metal tags were introduced.

RFID Anti-Metal Tag: ABS

ABS anti-metal tags adopt special antenna designs and are encapsulated with ABS engineering plastic. This design effectively prevents metal from interfering with radio frequency signals, enhancing reading performance, and in some instances, the reading distance is even farther than in the air. ABS anti-metal tags can reliably operate on both metal and non-metal surfaces. By installing RFID tags on assets and integrating with a real-time monitoring platform in data centers, comprehensive asset visualization and real-time information updates can be achieved.

Main Features

• Applicable to frequency ranges of various countries worldwide

• Suitable for use on metal or non-metal surfaces

• Available in various sizes, stable performance, waterproof and collision-resistant

• Easy to install, suitable for both indoor and outdoor environments

Application Areas

ABS anti-metal tags are widely used in the asset management of IT servers and equipment, inspection of open-air power equipment, management of pressure vessels and automobile parts, etc. They are also suitable for warehouse management to identify individual shelves and remotely read tag information through a reader, thereby improving inventory management efficiency.

RFID Anti-Metal Tag: PCB

PCB anti-metal tags are a type of multi-medium application UHF ultra-high frequency passive tag designed specifically for adhesion to metal surfaces. They are encapsulated with special FR4 material, boasting features such as high temperature resistance, moisture resistance, and corrosion resistance. The PCB anti-metal tag design simplifies the installation process, as the tag can be directly adhered to metal objects, making it easy to record and track product information, thus enhancing asset management efficiency.

Main Features

• Encapsulated with FR4 material, high temperature and corrosion-resistant

• Good read/write performance, suitable for harsh outdoor environments

• Can silkscreen logo, QR code, enhancing the identification function

Application Areas

PCB anti-metal tags are widely used in the asset management of the medical and IT industries, management of weapons and firearms, maintenance of power equipment, etc. They are also suitable for tracking precast concrete in the construction industry, providing a reliable solution for the management of large equipment and components.

Installation Methods for RFID Anti-Metal Tags

Installation Methods for RFID anti-metal tags directly affect their performance and durability. In practical applications, choosing the appropriate installation method is crucial:

Adhesive Installation

This is the most common installation method, suitable for most environments. However, in extremely cold or humid environments, the performance of adhesives might be affected, so choosing the right adhesive material for specific environments is necessary.

Epoxy Adhesive Installation

Epoxy adhesive has strong adhesion and is suitable for industrial environments. However, epoxy adhesive is relatively expensive, necessitating consideration of budget factors.

Screw Fixing and Cable Tie Installation

In some mechanical equipment with reserved slots, screws can be used to fix the RFID anti-metal tags. Cable ties provide a flexible installation method but are not suitable for environments exposed to UV light for extended periods.
