Multi-antennas and optimized electronics

With its 4 antenna ports, the ATX3 is the most flexible solution on the market and maximizes the user convenience. Up to 4 antennas can be connected on ATX3 and each antenna port is independently managed.



Communication interfaces and protocols

The ATEX & IECEx range of UHF readers is designed for seamless and flexible integration to existing management systems. A lot of communication interfaces to the system are available: TTL, RS232, RS485 or TCP-IP. On request, customer specific protocols can also be implemented.



Easy integration and installation

ATX3 readers are easy to adapt to an existing configuration. They do not require any electronic tuning for a quick and simple setup. The ATEX & IECEx range features two versions: read only (ATX3R-E) or read write (ATX3W-E).
