RFID Transponders & Reading Equipment

LF / 125 kHz & 134 kHz

LR95L. Read/Write Unit

Antenna and electronics integrated in an industrial compact unit. 120 mm x 200 mm x 30 mm polycarbonate enclosure. Reading distance is 20 mm to 200 mm, depending on type of transponder. Can be used with several different standards. Programmable via a simple ASCII protocol interfaces including RS 232C and RS 485. Power supply, 10-30VDC. Relay output.


IS203S. Read/Write Unit

A range of R/W units specially designed for the harshest possible environments such as mines and vehicle assembly.

Heavy-duty construction made of polyacetate. Addressable and equipped with RS 485 interface. Power supply, 10-30VDC.

ATEX approved version is available.



We can offer most things related to RFID transponders.

Code carriers, reprogrammable and "OTP," predominantly within the industry standard 125 kHz. Cards, key rings, glass ampules. Specially made for mounting on sanitation containers, calibrated for montage on metals, high temperatures, etc. Contact us regarding requirements, standards and frequencies, like SmartLabel EPC, 132KHz, 13.56Mhz.

Regardless of name, transponder tags and chips (i.e. information carriers) have basically the same structure.

Low-frequency passive 125 kHz RFID transponders are electronic memories consisting of a piece od silicon, an antenna and a protective enclosure. These materials have very diverse properties and it is essential to choose the right transponder, with regard to its enclosure, depending on the application.

Labeling of bins in sanitation and waste management is perhaps the most demanding and difficult application possible. The transponders are exposed to weather, wind and UV radiation, while being fastened on various types of materials, including metals. They are expected to work for decades in temperatures ranging from -30 to +60°C, as well as withstand vibrations and shocks (from handling and garbage trucks) and direct physical violence.

Paying a higher price for the right transponder for the job is an insignificant cost compared to having to replace a failed transponder in the field.

Liros has long experience with transponders in various environments, which enables us to offer you the right product in terms of price and quality for your application.

RFID transponders

UHF / 869 MHz


Palomar is the umbrella name for our long-range passive RFID systems. It is capable transaction distances up to 10 metres and have anti-collision.

Palomar is working with Atmel's new TAGIDU transponder chip.

The UHF transponders are often rectangular and thin, typically 110 mm x 30 mm x 1 mm.


Wireless / Modems

RCU. License-free 2.4GHz radio

RCU is an industrial frequency-hopping spread spectrum (FHSS) radio for the license-free 2.4 GHz band. The technology makes it very insensitive interferences and the indoor coverage is very good.

The RCU has 16 different channels / hope patterns and handles roaming. Up to 64 units can be addressed on each channel. It works at up to 460 kbps.

Typical applications are crane communication systems and AGV.


Multi-modem. Intelligent GPRS modem

A General Packet Radio Service (GPRS) modem for communication over the telephone lines.

The modem is designed for continuous operation and has special features including PIN management and re-connection to the telephone network during "ghost connections." Inputs and outputs make it possible to use the modem for remote control and transmission of text messages or alerts.

Especially designed for communications with the mobile computers and control them via remote. The modem can also beconnected to the car alarm.
