Impinj M775 Wet Inlays: What to Confirm Before Ordering
An Impinj M775 wet inlay is an adhesive passive UHF RFID inlay built around the M775 chip. To source a replacement or qualify a new inlay, confirm the finished inlay part number, antenna dimensions and application. The chip model identifies one component. The antenna and label construction determine how the finished inlay fits and performs in your setup.
Do you need the same chip or the same finished inlay?
If you are reordering an approved inlay, send the manufacturer’s part number, datasheet or a reference sample. Confirm whether your project requires the exact inlay or allows a different antenna design using the same M775 chip.
If you are qualifying a new inlay, start with the available space, the mounting surface and the intended reading process. Two inlays built with the same chip may perform differently on the same product. See Impinj’s M700 Series chip specifications.
What should be on the purchase specification?
| Item | What to confirm |
|---|---|
| Inlay construction | Manufacturer’s part number, antenna dimensions, die-cut size, adhesive and liner |
| Application | Mounting surface, packaging material and any nearby metal or liquid |
| Reader setup | Deployment country, reader model, reading position and item orientation |
| Roll format | Liner width, pitch, core diameter, maximum roll diameter and unwind direction |
| Encoding | Blank or pre-encoded supply, EPC format, serial assignment and readback requirements |
Impinj specifies 128 bits of EPC memory and 32 bits of user memory for the M775. Check your intended encoding against the chip specification and the requirements of your reader software or customer. See Impinj’s memory organization reference.
How should you qualify an M775 wet inlay sample?
Test the candidate on the actual item or finished packaging. Use the intended reader and repeat the planned workflow, whether that is handheld inventory counting, a fixed read point or a converting trial. Record missed items and any reads from neighboring items that should be outside the read zone.
For roll-fed projects, also check that the liner feeds correctly, the pitch matches your equipment and the inlay stays in the intended position after converting.
What should you send Nexora for a supply check?
Send the existing inlay reference or required dimensions, the application, deployment country, estimated quantity and any roll or encoding requirements. If you can accept a different antenna design, let us know so we can check which options can be evaluated. Sample availability, minimum order quantity and lead time can be confirmed against the proposed construction.
Ask Nexora to check M775 wet inlay availability or explore our UHF RFID inlay and label converting options.
