Contactless Data and Power Transmission


RoProxCon® - The innovative connection technology from Rosenberger for future requirements

Due to increasing automation, more and more electromechanical systems used in industrial plants are being connected to one another. Cables and plug contacts are often under considerable stress, causing cables to deteriorate or even break, and overused plug contacts to fail, resulting in machine downtime.

The advantage of contactless transmission is that inflexible electromechanical couplings are no longer required while the radio technology offers a high degree of additional flexibility. For example, at times when systems need to be changed.

Previously, however, wireless transmissions using Bluetooth, WLAN, wireless IO-Link, ZigBee etc. have not always met all the necessary requirements.

RoProxCon® is an innovative connection system that bridges construction-related air gaps with high interference immunity. This transmission, realized by radio transceivers in the mm wave range, offfers advantages in applications where there are high requirements for low maintenance and freedom from wear. With RoProxCon®, existing applications can be improved while also allowing new solutions to be created for previously unrealizable scenarios.


Protocols - Basis for electronic data transmission

With RoProxCon®, Gbps transmission in full-duplex is possible. In addition, this solution allows data to be transmitted regardless of the protocol used. This means RoProxCon® is transparent in the transmission channel. A wide variety of transmission standards are possible through adaptation circuits.  Furthermore, real-time capability is guaranteed by the very low latency. Use in time-critical applications, e.g. in automation technology is therefore possible without restriction.
