LFM Reader


In the world of RFID technology for the semiconductor industry, the LFM 4x Reader from HERMOS represents a remarkable innovation. This advanced read/write device from the HERMOS LFM (LF Midrange) class opens up a wide range of possibilities in the identification and tracking of objects. Its seamless communication with passive transponders in the LF range (134.2 kHz) makes it an outstanding choice for demanding applications.

What really sets the LFM 4x reader apart from the crowd is its remarkable ability to operate reliably even in metallic environments. This feature greatly expands its range of applications as it proves itself in difficult and challenging environments.

Versatile connectivity redefines the LFM 4x reader. With four antenna ports, it enables seamless linkage to multiple wafer transport box loading stations. This impressive flexibility gives companies the opportunity to manage their resources even more efficiently and save costs when subsequently automating processes.

Another key feature is the individual tuning of each antenna. Each of the four antenna ports has its own independent antenna tuning. This ensures that the connected antenna is optimally matched to the specific environmental conditions. This technical sophistication maximizes data acquisition efficiency and accuracy.

In terms of data interfaces, the LFM 4x Reader relies on proven standards. Both RS232 and Ethernet are available as reliable options. These interfaces ensure smooth integration into existing systems and facilitate data acquisition and analysis. Both ASCII and SECS/HSMS are available as software protocols.

Overall, the LFM 4x Reader manifests itself as an outstanding next-generation read/write device. Its identification, tracking and data capture capabilities set new standards. Its adaptability, performance and precision make it ideal for the semiconductor industry and its specific applications.
