The 433 MHz M172-i IR Durable Tag is a battery-powered RF transmitter
designed with a sealed, water-resistant, crush-proof enclosure
for general-purpose asset tracking. Every tag broadcasts its unique
ID and a status message at a periodic rate (that is programmed
at the factory). These tags provide an economical solution for
a variety of asset tracking environments. RF Code’s patented communication
protocols support high tag densities that allow large populations
of tags to be deployed in confined spaces.
M172-i IR Durable Tags are equipped with on-board infrared (IR)
and motion sensors. This family of tags is designed to be deployed
in concert with RF Code’s IR Room Locators. IR-enabled tags monitor
their environment for incoming IR signals and periodically report
both their own unique ID and IR location codes. Motion activation
allows the tag operate at 2 beacon rates: slow when the tag is
stationary, and faster when the motion sensor is activated. This
provides a method for rapidly locating mobile assets Tagwith room-level
accuracy. Since location is determined via the IR room code, there
is no need for deploying multiple overlapping readers or performing
complicated signal strength calculations or triangulation algorithms
to determine tag location.
M172-i IR Durable Tags are impact-resistant, splash-resistant
and temperature stable. Labels are sealed on the inside of the
clear polycarbonate enclosure via sonic-welding at the point of
manufacture. This protects both the label and the electronics
from moisture and fluids. The durable enclosure provides excellent
resistance to harsh environments; it can withstand salt water
splashes, cleaning solutions, germicides, disinfectants, etc.
Powered by a coin cell battery, the M172-i tag will perform reliably
in extreme temperature environments (from -20 to +70 degrees Celsius).
In addition, the tag performs well after exposure to humidity
and hot/ cold cycles. The tag operates with a very low duty cycle
that translates to long battery life. Based on the ratings and
specifications from the battery manufacturers, RF Code develops
usage models to calculate the life of the active RFID Tags. Like
all models, there are assumptions and approximations involved.
The values are to be taken as engineering estimates - not guaranteed
performance. Exposure to extreme temperatures will shorten the
battery life. RF Code warrants all tags to be free from defects
in materials and workmanship for a period of 1 year.
