Xtreme RFID | XTR VX-Mini HT (High Temp) is a UHF RFID tag solution to tracking metal assets exposed to high temperatures and harsh environments. Designed specifically for on-metal applications, the tag combines good read range with a tiny form factor. Industry leading performance is achieved using the Alien Technology Higgs 3 IC, and one-piece encapsulation sealing the tag off from the elements. With an ingress protection rating of IP69K, your asset will be impenetrable to moisture, dust, and chemicals. Retrieve reliable reads from both fixed and handheld readers providing flexibility in your process. Integrated mounting holes allow attachment to assets in multiple ways (Rivets or screws, 3M VHB adhesive, or zip-tie).
