EM4026

R EM MICROELECTRONIC - MARIN SA 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. Features ! Implements free-running anti-collision protocol with FAST SWITCH-OFF and SLOW-DOWN modes ! Ability to identify a number of transponders higher than 100 (FAST MODE) ! Factory programmed 64 bit ID number ! Data rate options from RF/4 to RF/32 ! Manchester data encoding !
