UHF RFID Cable Tie Tag, 330 mm, for Traceability: overview
The ST-140 is a UHF RFID cable tie tag: a PP zip tie with a flat 53.5 × 30 × 1.9 mm tag head, 330 mm long overall. It attaches an ID to anything that can be looped, such as cable bundles, hose and pipe runs, sacks, parcels, garment bundles, sample bags and plant stems, where an adhesive label would peel or has nothing flat to stick to.
Inside the head is an Impinj Monza 4QT chip covering 860–960 MHz. Read range is short: 0.7 m with a 4 W fixed reader and 0.2 m with a handheld. That makes the tag a good fit for traceability steps where items are scanned one by one at a workstation, packing table or checkpoint, and a poor fit for reading at a distance.
Each tag carries a globally unique chip ID, and UHF anti-collision lets a reader handle several tags at once when they are within range. Record the ID when the tie goes on, then scan it at each step to build a chain of custody for the bundle or package.
Integration notes
The strap fastens like a standard plastic zip tie, and like one it is normally cut to remove. It is a traceability tag rather than a security seal, so pair it with a one-time steel-wire seal such as the ST-110 where tamper evidence matters.

ST-140 FAQ
How close does the reader need to be?
The datasheet lists 0.7 m with a 4 W fixed reader and 0.2 m with a handheld, so plan for scanning at a station or with the handheld held close to the tag.
Is it a tamper-evident seal?
No. It is a traceability tie. For visible tamper evidence on doors, hasps and valves, use a one-time steel-wire seal such as the ST-110 or ST-120.
Can the tie be reused?
Treat it as single-use. Like any tightened zip tie, removing it normally means cutting the strap.
Which UHF readers will read it?
Any EPC Gen2 reader operating within 860–960 MHz, covering both the 902–928 MHz and 865–868 MHz bands.
