UHF RFID PCB Strip Tag IDTS-2504 (25 × 4 mm)

A UHF RFID strip tag for items too small for a label

The IDTS-2504 is a passive UHF tag cut down to a 25 × 4 mm strip of green PCB. That narrow footprint fits along the edge of a circuit board, on a slim handle or beside a cable run, places where a card-sized tag or a standard label would overhang. The chip sits under a small black epoxy dome in the centre; the dome is the 1.8 mm high point, and the rest of the strip is thinner.

Fixing it, and where it works

Four through-holes at the corners let you screw or rivet the strip to the item instead of relying on adhesive alone. That helps on harnesses, boards and fixtures that vibrate, run warm or get wiped down. The rated operating range is −20 °C to +150 °C.

This is not an on-metal design. Like most standard UHF tags, it detunes when laid flat on metal or against liquid, so use it on plastic, composite, wood or board material. For a metal asset of similar size, look at the IDTS-2510 on-metal PCB tag (25 × 10 mm).

Read range and readers

Expect about 1 m, which suits reads with a handheld or desktop reader at a workstation, test bench or store counter rather than long-range portals. The U8 chip on ISO 18000-6C holds a 128-bit EPC for your serial number plus a 96-bit factory TID, and reads on standard UHF equipment. See more PCB and ceramic RFID tags.
