White paper | Contactless Power and Data Transmission with NearFi Technology

Near-field communication Contactless Ethernet transmission in the 60 GHz near field via defined air gaps of a few centimeters.

Ethernet in real time Bidirectional communication without additional system-related latency supports time-critical Industrial Ethernet protocols( e. g., PROFINET, EtherCAT).

Low-interference coupling Locally limited coupling reduces the risk of interference and simplifies commissioning in environments with high RF density.

Flexibility The couplers enable direction-independent coupling – including rotational coupling – without the need for precise alignment; offset and angular deviations are tolerated.

Inductive power transmission The optional inductive power transmission enables a wear-free power supply, ensures electrical isolation, and reduces maintenance requirements.
