V680-D2KF67/-D2KF67M
General Specifications
Note: The total communication frequency of the Read or Write is called an access frequency.
The V680-D2KF67M is designed to be mounted directly to metal. The V680-D2KF67 and V680-
D2KF67M markings are shown in the following diagrams.
The side with the markings is the communications surface. Mount the Tag with this side facing the Antenna.
The ID code is written in the memory of the Tag and may be affected by data retention characteristics at high tempera-
tures. Take suitable precautions when using the READ ID command for Tags operating at high temperatures.
