EM4026
Read only Contactless Identification Device
Description
The EM4026 passive transponder is a single chip with
anti-collision features enabled. The free-running algorithm
is very well suited to environments sensitive to the
potential jamming caused by the reader’s modulation.
With this feature the reader only sends a Continuous
Wave and listens to incoming replies from the tags. In the
standard Free-Run operation very few numbers of tags
can be counted with high throughput. The Fast Switch-Off
and Slow-Down enables the possibility of counting a high
number of items, typically for logistics applications.
A single coil is connected to the naked chip in order to
make the passive tag.
