C.1.3  MDS D139 (MLFB 6GT2600-0AA00) 
Application area 
These reusable, cyclic heat-proof transponders with a limited service life are required for use 
in production logistics and in assembly lines subject to high temperatures (up to +200 °C). 
The MDS D139 is a passive, maintenance-free transponder with 44 bytes of user memory. 
This data storage unit is considerably less expensive than the heat-proof mobile data 
storage units available today due to its simple construction (without thermal insulation), but 
also due to its lack of complexity.
