LF

The HERMOS RFID LFM reader is a read/write device of the HERMOS LFM class (LF midrange), which communicates with passive transponders in the LF range (134.2 kHz). The reader can also be used in metallic environments. With four antenna connections, linking to multiple identification points is possible. Each antenna connection has its own antenna tuning, with which the connected antenna is tuned to the ambient conditions. RS232 and Ethernet are available as data interfaces.

Four antenna ports
Cost-saving concept due to the extended number of identification points.

Various configurations available
The number of available four antenna ports can be customized. Different I/O modules are available.

RS232 and Ethernet interface
Easy and uncomplicated integration due to RS232 and Ethernet interface. ASCII and SECS/HSMS are available as data protocols.

The reader has the following protocols:

  • SECS/HSMS
  • ASCII HERMOS
  • ASCII Brooks Automation

Automatic tuning
Flexible reading range, adjustable according to requirements. Optimal adaptation of antenna tuning to environmental conditions. Automatic detection of antenna breakage (defective antenna or feed line).

Power over Ethernet (PoE)
Savings potential through the use of PoE within the network infrastructure, relief of the cost budget through fewer power supply units and less cabling.

Polling mode adjustable for each antenna
Automated reading processes simplify operations and control efforts.

Configurable test mode with visual display
Visual monitoring of read characteristics through configurable test mode using DIP switches.
