RFID transponder at a station near you!

The Harting Ha-VIS RF-R500 RFID transponder has been successfully tested in accordance with the European Standard EN 50155 for deployment on railway rolling stock.

RFID (radio-frequency identification) is a technology that is rapidly gaining ground in rail applications. Its special feature is the fact that the transponder, containing the unique number and memory identifying a specific object, does not need batteries and is supplied with energy wirelessly via the RFID reader instead.

Specific benefits of RFID in rail applications include the fact that its operation is not affected by dirt or soiling, the maintenance-free characteristics of RFID transponders and readers, and the ability to link the RFID components via relays or networks with train control systems.

The EN 50155 standard lays down stringent conditions regarding electromagnetic compatibility, shock and vibration. The fact that the Ha-VIS RF-R500 RFID reader has been successfully tested against EN 50155 for application on rolling stock opens up entirely new possibilities for rail applications.

Typical applications include platform detection, train positioning systems, wagon-load recognition, and driver information systems.
