What Is a UHF RFID Wet Inlay?

A UHF RFID wet inlay is a passive RFID inlay consisting of an RFID chip, antenna, adhesive and release liner. It can be converted into RFID labels, stickers and tags for item-level identification, inventory management, logistics tracking and asset identification.

Operating in the 860–960MHz UHF range, wet inlays are designed for applications that require fast identification and longer read distances than typical HF or NFC systems.

The right inlay depends on the required read range, chip performance, antenna design, tag size, application material and RFID reader configuration.

UHF RFID Wet Inlay Specifications

Our UHF RFID wet inlays combine an RFID chip and antenna with an adhesive layer and release liner, providing a flexible solution for RFID labels, stickers and converted tags.

* Actual read range depends on chip sensitivity, antenna design, reader configuration, tag orientation and application environment.

Wet Inlay vs. Dry Inlay vs. RFID Label

Understanding the difference helps buyers select the right RFID format for their project.

A wet inlay is often selected when an adhesive-backed RFID inlay is required for further converting or direct application.

Chip and Antenna Options

Different RFID applications require different combinations of chip sensitivity, memory, antenna size and operating characteristics.

Available configurations can include compatible Impinj and Alien chip options, with the final selection based on your application requirements.

Common selection factors

· Required read range

· EPC and user memory requirements

· Reader compatibility

· Tag dimensions

· Tagged material

· Operating environment

· Required encoding capability

· Target production quantity

If you are unsure which chip is suitable, send us your RFID reader model, application, target size and required read range. Our team can recommend a suitable configuration for testing.

What Affects UHF RFID Read Range?

The read range of a UHF RFID wet inlay is not determined by the chip alone.

Actual performance can be affected by:

RFID chip sensitivity

Antenna design and size

RFID reader power

Reader antenna

Tag orientation

Distance and angle between tag and reader

Tagged material

Metal or liquid near the tag

Installation environment

Our current specification range is 0.2–8m, but actual performance should be verified under the customer's intended application conditions.

For demanding environments involving metal, liquids or unusual surfaces, application-specific RFID tag designs may be more suitable than a standard wet inlay.
