8 m PCB Anti-Metal UHF RFID Tag, 52 × 13 mm: overview
OM-180 is a hard FR4 circuit-board tag for metal assets where an ABS housing would be too bulky. At 52 × 13 × 3.9 mm it suits tools, instruments, IT hardware, medical equipment and firearms, and it is rigid enough to be fixed mechanically through the hole at each end.
The datasheet quotes 8 m on a metal surface with a 4 W fixed reader and 3.5 m with an Impinj R2000-based handheld, from a board under 4 mm thick. The chip is an NXP UCODE 8, and the tag is listed for 902–928 MHz and 866–868 MHz. Order OM-180-US or OM-180-EU to match your reader's regional band.
Within our PCB range, OM-180 sits between the long-range OM-190 (90 × 20 mm, 10 m) and the compact OM-200 (25 × 10 mm, 3 m). It is a good default when you want fixed-reader range from a tag that still fits on a tool body or equipment rail.
Integration notes
Mount the tag flat against the metal. The datasheet lists no hole size, adhesive or potting option, so confirm your fixing method on samples; screws, rivets or industrial adhesive are all common for PCB tags of this size. Because the chip is EPC Gen2, you can encode your own numbering with any Gen2 reader-writer.

OM-180 FAQ
What read range does OM-180 give?
8 m with a 4 W fixed reader and the tag on metal, and 3.5 m with an Impinj R2000-based handheld, per the datasheet.
Which band variant should I order?
OM-180-US for 902–928 MHz readers and OM-180-EU for 866–868 MHz readers. We confirm the band with you before dispatch.
How thick is it?
3.9 mm. The full size is 52 × 13 × 3.9 mm on an FR4 circuit-board substrate.
Can it be embedded or potted into a part?
The datasheet does not cover embedding or potting. Tell us the material and pocket size and we will test samples for your application.
