New battery-less relay can be activated and deactivated wirelessly

Spanish company, Farsens S.L., has unveiled the TITAN a battery free RFID bistable relay tag. These tags are compatible with commercial EPC C1G2 readers and can be wirelessly activated and deactivated via their unique ID and the relay keeps its latest status even when the RFID reader is gone.

The TITAN has a 96 bits EPC number, a 32 bit TID and a password protected Kill command. Built in a PCB format, it is available in different sizes. The communication range is up to 1.5 meters and the operating temperatures are from -30°C to +85°C (-22°F to +185°F). These actuator tags are available in a variety of antenna design and sizes, depending on the specific application. It can be encapsulated in an IP67 or IP68 casing for usage in harsh environments.

The fact that the actuator is fully passive makes this relay suitable for hard to access or restricted areas and for those applications where the use of batteries is not recommended. The TITAN will never require a battery change, saving the costs associated to maintenance.

TITAN tags are used in energy scarce applications where the stored energy is limited and the system/circuit is controlled via a wireless battery-free relay. The circuit can be opened and closed from a commercial RFID reader. The bistable relay allows the system to run so that the limited battery is only switched on during the time the user actually needs it to be running.

Battery-free relays are also a good fit for retrofitting in places where lots of mechanical relays are being manually operated. The fact that each relay is uniquely identified by its ID number makes automation a lot easier and activation/deactivation can easily be implemented with simple to use reader software.

Farsens designs and manufactures full passive RFID sensor solutions. The company’s proprietary UHF RFID IC allows it to develop a broad range of solutions for asset tracking – via the unique ID – and monitoring – via the attached sensor – without the need of any battery on the tag.
