About the Identium UHF RFID PCB Tag D18-25

The detail that separates the D18-25 from the discs around it is the 2 mm aperture through its body. That single hole makes this Identium on metal UHF tag India customers can bolt down rather than glue, which matters on machinery that vibrates, gets washed or sees an annual repaint. The D18x2.5 mm PCB body carries an H9 chip and is rated up to 150 cm on metal, so a maintenance technician can capture an asset from across a bay. It suits plant equipment, safety gear, metal pallets and access equipment that has to stay identified for years.

Key specifications

Best-fit applications

• Machine frames and gearboxes where a screw fixing outlasts adhesive
• Fire extinguishers and safety equipment on statutory inspection rounds
• Metal pallets, cages and roll containers in a closed-loop pool
• Aluminium ladders and access equipment issued to site crews
• Pumps, motors and valves on a preventive maintenance route
• Switchgear and panels counted in a plant asset audit

Mounting, encoding and reading notes

Use the 2 mm aperture: an M2 screw or a small rivet through a drilled and tapped hole holds the tag flush for the life of the asset, and a nylon washer under the head stops the disc cracking when the fitter over-tightens. Keep the tag face proud and unpainted, and mask it before a repaint to preserve the read. Encode each tag at the stores counter before it goes to site, and if a tagged item ends up boxed inside a steel cabinet, open the door or read from the front face instead of raising reader power.

Why buy from Identium

Every D18-25 is made in India by Identium, which has manufactured RFID hardware since 2010. The tag is tuned for 865-868 MHz, the same band ETSI uses, so export orders need no change of part. We support bulk and OEM programmes, encode to your scheme and supply samples on request. Explore the on-metal RFID tag range or fix read problems with our RFID troubleshooting guide.
