The 433 MHz M171 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.

M171 Tags can be programmed to operate at a 2-second beacon rate for security applications. This provides a method for rapidly locating and identifying tagged assets as they move through controlled areas. With typical read ranges of 300 feet, a single reader can provide coverage for a large area, such as an industrial laboratory or commercial warehouse.

The Durable M171-series 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 a degree of protection in harsh environments; it can withstand salt water splashes, cleaning solutions, germicides, disinfectants, etc. This enclosure design has been evaluated for compliance with Ingress Protection Rating 54 (IP54).

Powered by a coin cell battery, the M171 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.  In most deployment scenarios, tags with a 10-second beacon rate have a useful life of 5-to-7 years.  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.
