About the Identium UHF RFID PCB Tag D20-25

Built for equipment that lives outdoors, gets hosed down or travels between sites, the D20-25 PCB tag is a D20x2.5 mm on-metal disc with an H9 chip and a generous 3.5 mm aperture. That larger hole takes a machine screw or a standard pop rivet, so the tag is fixed mechanically to the asset rather than trusted to adhesive alone. Rated up to 120 cm on metal, it reads comfortably from a handheld held at arm's length. Indian rental fleets, facility teams and maintenance departments use this size on motors, formwork, drums and machinery that adhesive-only tags rarely survive.

Key specifications

Best-fit applications

• Hired construction equipment and metal formwork panels
• Motors, gearboxes and compressors on a plant asset register
• Outdoor HVAC units and chillers checked on facility rounds
• Metal drums and IBC cages in a chemical plant yard
• Tool cabinets and workshop trolleys in an MSME unit
• Fleet workshop spares held in steel bins and racks

Mounting, encoding and reading notes

The 3.5 mm aperture is sized for a machine screw or a pop rivet; drill and tap a flat boss, seat the disc flush and add a soft washer so the fastener does not crush the board. Where drilling is not permitted, epoxy the tag and use the hole for a safety wire. Load the EPC before the asset leaves stores, keep the tag face clear of grease and paint, and stand square to the disc when scanning, since reading off the edge will fall well below the rated 120 cm.

Frequently asked questions

What is the read range of the Identium D20-25 UHF RFID PCB tag?

The Identium D20-25 UHF RFID PCB tag reads up to 120 cm on metal. The distance you achieve depends on reader output power, antenna gain and the metal surface the 20 mm disc is fixed to. It runs on EPC Class 1 Gen2 / ISO 18000-6C over 860 to 960 MHz.

Does this 20 mm RFID disc tag work on metal?

Yes, the D20-25 is an on-metal UHF RFID PCB tag built for direct mounting on metal tools, machines and assets. Standard paper or label tags fail on metal because the surface detunes the antenna, so an anti-metal PCB tag is required for reliable reads.

Can the D20-25 tag be screw mounted?

Yes. The D20-25 UHF RFID PCB tag has a 3.5 mm aperture, so it can be screwed or bolted onto a metal asset, and industrial adhesive can be used where drilling is not possible. This makes it practical for tool tracking and asset management in Indian workshops.

What is the price of on-metal RFID PCB tags in India?

The price of the D20-25 on-metal UHF RFID PCB tag in India varies with order quantity, so see the price listed on this page or request a bulk quote. India RFID Store is a BIS and WPC certified Indian manufacturer offering bulk and OEM pricing with pan-India shipping.
