2.0Choosing

Choose the LHB-D20-S, or look elsewhere

In favor

  • Choose it when the requirement is 200 wash cycles: the supplier states 200, or 24 months from the shipping date, whichever comes first. Confirm it with a wash trial on your own items.

Against

  • Avoid it when you need user memory: the record states EPC memory only.
  • Avoid it where the tag runs hotter than 110 °C in service: that is the stated operating maximum, and the higher storage figure of 120 °C is not an operating figure.

4.0Reading the figures

What the figures do and do not say

Next to its neighbors

LHB-D20-S comparisons below use supplier-stated records.

LHB-D20-S, LHB-D18-S and LHB-D25-S share a supplier-stated read ceiling of 0.4 m (EIRP 4 W, surface not stated).

LHB-D18-S reduces the circular outline from 20 mm on LHB-D20-S to 18 mm, a 2 mm reduction. LHB-D18-S needs 0.5 mm more height (2.8 mm) than LHB-D20-S (2.3 mm).

With LHB-D20-S, diameter stays at 20 mm; LHB-D25-S needs 25 mm, 5 mm more room across. LHB-D25-S needs 0.5 mm more height (2.8 mm) than LHB-D20-S (2.3 mm).

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 LHB-D20-S

Answers quoted from the record

How far can the LHB-D20-S be read?

The supplier states up to 0.4 m (EIRP 4 W, surface not stated) and up to 0.1 m (Alien 9011 handheld, surface not stated). TagBrio has not tested either figure, so read a sample on your own part before you rely on them.

How is the LHB-D20-S attached?

The record lists sewn with thread. Confirm the fixing on your own material and surface before you order in volume.

What temperatures does the LHB-D20-S state?

The supplier states an operating range of -25 to +110 °C and a storage range of -40 to +120 °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 LHB-D20-S list?

The record lists NXP UCODE 7 and NXP UCODE 7m as chip options. Memory: EPC 128 bit (supplier-stated).

Which frequency variants does the LHB-D20-S 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.

How many wash cycles does the LHB-D20-S state?

The supplier states 200 wash cycles, or 24 months from the shipping date, whichever comes first. TagBrio has not tested it, so run a wash trial on your own items.
