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.
