Down Hole Ceramic RFID Tag


  • Resistant to heat and cold
  • Chemical and solvent resistant
  • Small footprint RFID tag
  • Metal mount RFID tag



The WF-SM-DH down hole ceramic tag is useful when you need to embed an RFID tag in a small space like a tool handle. The tag has ideal thermal and chemical properties. As a metal-mount tag, the WF-SM-DH is unparalleled in both size and ruggedness. Reliable 100,000 cycle / 50 year retention capability.


The SM-DH performs so well that we use it in our WF-SM-75HT and WF-SM-75HTLE. It is a passive UHF EPC Class 1 Generation 2, ISO/IEC 18000-6C compliant RFID tag ensuring seamless interoperability.


Extra Small Footprint


The WF-SM-DH is extremely small. At only 0.75” L x 0.75” W x 0.125” H, this RFID tag can fit seamlessly into many products.


Metal Mount Heat Resistance


The WF-SM-DH performs best when the tag comes in contact with metal, though it will still function properly if attached to non-metal surfaces. This RFID tag has an extremely large temperature range suitable for applications where high or low heat is an issue.

Tested Polarization:


Tag performance was experimentally measured in an anechoic chamber and a known set of experimental variables. The antenna used for measurements was linearly polarized and of monostatic configuration. The direction of tested polarization is as follows.
















Optimal Read Range* on Different Material Surfaces:



*Tag performance was measured free of material influence, on a dry wood, window glass, thermoplastic, and steel slabs. Actual read ranges may differ depending on conditions such as environment, tag placements, hardware, etc.
