Semiconductor developer ST Microelectronics and Rosenberger, a provider of impedance-controlled and optical connectivity solutions, have collaborated on a contactless connector for ultra-reliable, short-range, point-to-point full-duplex data exchanges in industrial and medical applications.

The RoProxCon contactless connector designed by Rosenberger leverages the 60 GHz radio frequency transceiver from ST Microelectronics — the ST60A2 — to deliver high-speed data transmission while providing immunity to movement, vibration, rotation and contaminants such as moisture and dust, which can disrupt conventional pin-and-receptacle interconnects. The ST60A2 combines high-data-rate transmission at Bluetooth-like power consumption and promises a new range of medical and industrial applications that are no longer constrained by physical connections.

Data can be transmitted regardless of the protocol used, allowing 10/100/1000BASE-T1, EtherNetIP, Profinet and EtherCAT to be sent and received. Angular misalignment up to ±45° is acceptable, and the endpoints can spin relative to one another around their cylindrical axes in the hermetically sealed system.

The ST60A2 chip operates over -40° C to 105° C, has a footprint of 2.2 mm x 2.2 mm and consumes 70 mW of energy.
