Silicone UHF RFID Laundry Tag, 55 × 12 mm, 902–928 MHz: overview
The LT-140 is a 55 × 12 × 2.7 mm UHF RFID laundry tag sealed in silicone. The encapsulation keeps water out and stands up to heat, corrosion and abrasion, and silicone is non-toxic and a good electrical insulator, which matters for towels, bedding and uniforms that sit against skin.
The antenna is tuned for 902–928 MHz, the FCC band used in the US and Canada, and carries an Alien Higgs-9 chip. Listed read distance is 4 m with a 4 W fixed reader and 2 m with an Impinj R2000-based handheld, enough for cart-level counts at a dock door, a soiled-linen intake or a clean-linen dispatch point.
No 865–868 MHz version is listed. For ETSI-band sites, the LT-130 PPS button is rated 860–960 MHz; for the longest range on 902–928 MHz, the fabric LT-150 reaches 7.5 m.
Integration notes
The narrow strip lies flat along a hem or seam. Encode the EPC with an EPC Gen2 reader-writer when the item enters service, then read at intake and dispatch to build circulation counts per customer or ward. Wash-cycle count and pressure limits are not published for this silicone version, so run samples through your wash, extraction and finishing program before rollout.

LT-140 FAQ
Can I use the LT-140 in Europe?
It is tuned for 902–928 MHz only, and no 865–868 MHz version is listed. For ETSI-band sites, consider the LT-130 PPS button, which is rated 860–960 MHz.
How far can it be read?
About 4 m with a 4 W fixed reader and 2 m with an Impinj R2000-based handheld. Wet or tightly packed linen shortens this, so tune antennas with loaded carts.
What does the silicone casing protect against?
Water, heat, corrosion and abrasion. The silicone is also non-toxic and insulating. Ask for wash-cycle and pressure data if your process uses high-pressure extraction.
Which chip is inside?
An Alien Higgs-9 EPC Gen2 chip, which standard UHF fixed readers and handhelds on the 902–928 MHz band can read and encode.
