Slim On-Metal Ceramic UHF RFID Tag, 23 × 9 mm: overview
The CT-130 is a narrow 23 × 9 × 3 mm ceramic UHF RFID tag for metal items that offer little flat area: tool handles, instrument edges, rails, brackets and the rims of housings. It carries an Alien Higgs-9 EPC Gen2 chip and is listed for both 902–928 MHz and 866–868 MHz operation, so it can be ordered for either major UHF band.
Rated read distance is 4 m on metal with a 4 W fixed reader and 3 m with a handheld reader. That is enough to capture tagged items as they pass a reader portal at a tool crib, or to check a shelf of parts with a handheld without handling each one.
The body is ceramic with a printed silver-paste antenna, and the chip is bonded to the antenna and encapsulated in epoxy resin. A strong pre-applied adhesive holds it in place. A tag that is forced off breaks its antenna and stops reading, which prevents quiet swapping of IDs between assets.
Integration notes
Order CT-130-US for 902–928 MHz readers or CT-130-EU for 866–868 MHz readers. Give the tag a flat seat at least as large as its footprint and keep its face unobstructed. No temperature, chemical or IP rating is published, so qualify it with a sample before using it in wash-down, outdoor or heated environments.

CT-130 FAQ
Which version do I need, US or EU?
Order CT-130-US if your readers operate at 902–928 MHz and CT-130-EU if they operate at 866–868 MHz. Chip, size and rated range are the same.
What read range should I plan for?
The datasheet lists 4 m on metal with a 4 W fixed reader and 3 m with a handheld. Allow margin for your reader, antenna and mounting, and confirm with a sample.
Can it go on curved surfaces?
The ceramic body is rigid, so it needs a flat seat of at least 23 × 9 mm. On curved parts, test adhesion and reading with a sample first.
Can a tag be moved to another asset?
No. Forced removal breaks the antenna and the tag stops responding, so each ID stays with the item it was first applied to.
