Therefore, careful coordination between the transmission unit and the housing is necessary to ensure reliable operation, even under demanding industrial environmental conditions.

Development and Evaluation of Contactless Transmission Systems

Modular development and evaluation platforms are often used to implement contactless power and data transmission in industrial and technical applications. These platforms typically consist of compact radio modules designed for stable data transmission over short distances, enabling a rapid technical assessment of the transmission technology. These platforms serve as practical tools for development teams, original equipment manufacturers (OEMs), and system integrators. They enable testing of transmission characteristics under realistic operating conditions, validation of interfaces, and preparation for integration into existing system architectures. This enables customer-specific applications to gradually transition to contactless transmission concepts, be evaluated, and be further developed without committing to a specific production design prematurely.

Conclusion

Contactless connection systems are a significant advancement in industrial automation. These systems meet the key requirements of modern manufacturing environments by offering high dynamics, minimal maintenance, and reliable communication, even under difficult conditions. With the right solutions, a future-proof and field-proven technology is available to design the interfaces of tomorrow's industry efficiently and robustly today.
Contactless data and power transmission bridges air gaps using wireless technologies such as radio transmission, thereby preventing wear and contamination
The maximum possible offset for SoM, Data, and Hybrid is ± 2 mm

What is RoProxCon®

RoProxCon® is a contactless transmission solution from Rosenberger for the simultaneous transfer of data and electrical power across an air gap. Based on millimeter-wave radio technology operating at 60 GHz, the system enables data rates of up to 3.125 Gbps with high transmission stability.
This solution is specifically designed for industrial applications involving moving or rotating interfaces. Thanks to optimized antenna technology, stable data connections are possible despite varying distances, angular misalignment, and continuous rotation. Mechanical wear, which occurs with slip rings or connectors, is completely avoided.
RoProxCon® is protocol-independent, full-duplex capable, and supports unlimited 360° rotation. In addition to transmitting data, it can also transmit electrical power contactlessly. This enables the implementation of compact, low-maintenance interfaces for sensor, actuator, and control systems.
Typical applications include robotics, automated manufacturing, rotating machinery, tool-change systems, and other applications that demand high availability, service life, and data rates.
