2.0Choosing

Choose the MHP-46x31-TF, or look elsewhere

In favor

  • Choose it when the available surface is small: at 46 x 31 mm it is the 3rd smallest of the 7 plastic-housed on-metal tags in the family that state a size.
  • Choose it when read distance drives the decision: it states up to 6 m (EIRP 4 W, on metal), the 3rd longest of the 7 plastic-housed on-metal tags that state that footing (they range from 3 m to 12 m).
  • Choose it when tape alone is not enough: the record lists screw, rivet and glue as well as adhesive tape.

Against

  • Avoid it where the tag runs hotter than 95 °C in service: that is the stated operating maximum, and the higher storage figure of 200 °C is not an operating figure.

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.

8.0Questions

Questions about the MHP-46x31-TF

Answers quoted from the record

How far can the MHP-46x31-TF be read?

The supplier states up to 6 m (EIRP 4 W, on metal) and up to 2.5 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 MHP-46x31-TF attached?

The record lists adhesive tape, screw, rivet and glue. A 3.2 mm mounting hole is listed. Confirm the fixing on your own material and surface before you order in volume.

What temperatures does the MHP-46x31-TF state?

The supplier states an operating range of -25 to +95 °C and a storage range of -45 to +200 °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 MHP-46x31-TF list?

The record lists Alien Higgs-3.

Which frequency variants does the MHP-46x31-TF 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 MHP-46x31-TF be encoded or marked?

The record lists pre-encoding, laser marking and logo printing. Ask the team which combination is available for your order.
