2.0Choosing
Choose the MFR-9x4-T, or look elsewhere
In favor
- Choose it when the available surface is small: at 9.4 x 4.3 mm it is the 2nd smallest of the 19 FR4 on-metal tags in the family that state a size.
- Choose it when height is tight: at 1.6 mm high it is the thinnest of the 19 FR4 on-metal tags.
Against
- Avoid it when you need more than 0.5 m of read distance: that is its stated figure (EIRP 4 W, on metal), and 17 of the 19 FR4 on-metal tags that state that footing state more, up to 6.5 m.
- Avoid it when you want to fix it by screw, rivet or glue: the record lists adhesive tape only.
- Avoid it where the tag runs hotter than 85 °C in service: that is the stated operating maximum, and the higher storage figure of 180 °C is not an operating figure.

4.0Reading the figures
What the figures do and do not say
Next to its neighbors
MFR-9x4-T comparisons below use supplier-stated records.
MFR-9x4-T's supplier-stated headline is up to 0.5 m (EIRP 4 W, on metal).
MFR-9x4-T's next smaller catalog footprint is MFR-D5-T (5 mm diameter, 3 mm high). MFR-D5-T is 4.4 mm shorter but 0.7 mm wider than MFR-9x4-T's 9.4 x 4.3 mm rectangle; the round disc cannot preserve its 4.3 mm width envelope. Height changes from 1.6 mm on MFR-9x4-T to 3 mm on MFR-D5-T. Supplier-stated (EIRP 4 W, on metal): up to 0.5 m for MFR-9x4-T; up to 0.5 m for MFR-D5-T. Chip selection changes from MFR-9x4-T's NXP UCODE 7m to MFR-D5-T's NXP UCODE 8. Stated weight: MFR-9x4-T about 1 g; MFR-D5-T about 0.5 g.
MFR-9x4-T's next larger catalog footprint is MFR-10x5-T (10 x 5 x 3 mm). MFR-9x4-T to MFR-10x5-T: length increases by 0.6 mm, width increases by 0.7 mm and height increases by 1.4 mm. Supplier-stated (EIRP 4 W, on metal): up to 0.5 m for MFR-9x4-T; up to 1 m for MFR-10x5-T. The ATID AT880 handheld, on metal entry is up to 0.1 m for MFR-9x4-T, against 0.4 m for MFR-10x5-T (supplier-stated). Chip selection changes from MFR-9x4-T's NXP UCODE 7m to MFR-10x5-T's NXP UCODE 8.
Who states these figures
Every performance figure on this page is a supplier statement: read distance, wash life, temperature, tests, pressure and data retention. TagBrio has not tested them, and no test report, laboratory or standard is cited for them. A test envelope is a condition of a test, not a rating. Confirm each figure that matters to you on samples, on your own items and with your own reader.

| FR4 on-metal tag 10 x 5 mm MFR-10x5-T | You need a longer stated read distance | MFR-10x5-T is 10 x 5 x 3 mm, the smallest model of the family that states more. Under the same stated footing (EIRP 4 W, on metal) it states 1 m against 0.5 m. |
| FR4 on-metal tag 5 mm dia. MFR-D5-T | The available surface is smaller than 9.4 x 4.3 mm | MFR-D5-T is 5 mm diameter, 3 mm high, the next smaller model in the family. Under the same stated footing (EIRP 4 W, on metal) it states 0.5 m against 0.5 m. |
| FR4 on-metal tag 90 x 5 mm MFR-90x5-TF | Tape alone is not acceptable | MFR-90x5-TF lists adhesive tape, screw, rivet and glue and is 90 x 5 x 3 mm. Under the same stated footing (EIRP 4 W, on metal) it states 2 m against 0.5 m. |
| Plastic-housed on-metal tag 37 x 14 mm MHP-37x14-TF | The tag runs hotter than 85 °C in service | MHP-37x14-TF states an operating maximum of 115 °C and is 37 x 14 x 5.9 mm, in a different family. Under the same stated footing (EIRP 4 W, on metal) it states 3 m against 0.5 m. |

8.0Questions
Questions about the MFR-9x4-T
Answers quoted from the record
How far can the MFR-9x4-T be read?
The supplier states up to 0.5 m (EIRP 4 W, on metal) and up to 0.1 m (ATID AT880 handheld, on metal). TagBrio has not tested either figure, so read a sample on your own part before you rely on them.
How is the MFR-9x4-T attached?
The record lists adhesive tape. Confirm the fixing on your own material and surface before you order in volume.
What temperatures does the MFR-9x4-T state?
The supplier states an operating range of -25 to +85 °C and a storage range of -30 to +180 °C. A storage range is not an operating range, and a test envelope is not a rating. Both are supplier-stated.
Which chip and memory does the MFR-9x4-T list?
The record lists NXP UCODE 7m.
Which frequency variants does the MFR-9x4-T come in?
FCC at 902 to 928 MHz and ETSI at 865 to 868 MHz. The record also names China but states no band, so this page lists none. Say which region the tags will be read in when you ask for a quote.
Can the MFR-9x4-T be encoded or marked?
The record lists pre-encoding and surface painting. Ask the team which combination is available for your order.
