Product introduction

The Digitag-F type DTFT01 is a radio active tag, operating at
433,92 MHz in GFSK modulation.
The tag transmits continously a radio pulse with a period of 1 sec.
A special algorithm adds to the rated time period a small slot,
realizing, in this way, an anticollision system, which avoids the
overlapping of the RF signals of many tags when standing
simultaneously in the same field.
