RFID Multiplexer - one Reader, many Antennas


In many cases when setting up an RFID system it is not desirable to connect each and every antenna directly to a reader as this might mean having to operate a very large number of readers. To reduce complexity and hardware costs for readers dramatically, the use of a multiplexer can make sense. A multiplexer is a switch that switches the antennas connected to the reader, allowing to connect up to 16 antennas to one reader. In cases in which reading an antenna e.g. every 500 milliseconds is enough this approach can save hardware costs for readers which are often the most expensive item in an RFID system. Also, only one reader has to be controlled by the host which reduces system integration effort significantly.

This is why metraTec has developed and currently offers the world's largest portfolio of RFID multiplexers. We have multiplexers for both HF and UHF applications in the "low power" and "high power" ranges.

hfMux-4 HF Multiplexer

The hfMux-4 is our 4 port RFID multiplexer for HF systems with an operating frequency of 13.56 MHz and a maximum power of 2 W (in the -MP version) or 4 W (in the -HP version). It allows connecting up…

hfMux-8 HF Multiplexer

The hfMux-8 is our 8 port RFID multiplexer for HF systems with an operating frequency of 13.56 MHz and a maximum power of 2 W (in the -MP version) or 4 W (in the -HP version). It allows connecting up…

hfMux-16 HF Multiplexer

The hfMux-16 is a 16x RFID multiplexer for HF systems with 13.56 MHz operating frequency. It enables the operation of up to 16 antennas on a single RFID reader. This makes it possible to set up…

hyperMux-4 UHF Multiplexer

Beside our multiplexers of the HF series there is the hyperMux-4 for the UHF frequency range (868/915 MHz). The device uses 24V optically isolated IOs which are used by most PLCs as well as many UHF…
