ST, Rosenberger team for 60GHz connector replacement
A first-of-its-kind 60GHz system from Rosenberger and STMicroelectronics replaces pin and receptable connectors in medical and industrial applications

STMicroelectronics has worked with Rosenberger on a contactless connector for short-range, point-to-point full-duplex data links in industrial and medical applications.

Rosenberger’s RoProxCon uses the ST60A2 60GHz RF transceiver for 6.25Gbit/s data transmission for a connection that is immune to movement, vibration, rotation, and contaminants such as moisture and dust, which can disrupt conventional pin-and-receptacle interconnects. The ST60A2 inside the connector provides the data link with power consumption levels comparable to Bluetooth at 70mW.

The RoProxCon connection system, avoids construction-related air gaps over several millimetres with high interference immunity for connections in harsh environment or where sealing is required (see video below).

In the RoProxCon, ST’s transceiver is paired with an appropriate antenna, which offers excellent options for different areas of applications like smart factory, medical technology, connected devices, office equipment, conveyer technology, renewable energies, and other high-bandwidth applications.

Operating over an extended temperature range of -40 to +105°C in a 2.2 x 2.2 mm package footprint, the ST60A2 has a power consumption of 70mW for a reliable, completely contactless link.

“Pairing ST’s contactless connectivity technology with our interconnect expertise and antenna-design knowledge enabled us to create a first-of-its-kind module that transmits full duplex data at up to 6 Gbps with complete rotational freedom. Much less expensive than alternative optical connectors and using much less power than other RF technologies, the RoProxCon will let innovators loose to create new applications,” said Folke Michelmann, Executive Vice President Medical & Industries at Rosenberger. “In working with ST, we see limitless application possibilities for our connector, which provides high-reliability and high-throughput at low power.”

“We developed the ST60A2 contactless transceiver to allow customers to create reliable, high data-rate, extremely power-efficient wireless links. Rosenberger’s expertise in interconnects combined with our RF chip is an outstanding example of the value of the technology,” said Laurent Malier, RF & Communications Division General Manager, STMicroelectronics. “Customers across the full range of electronics applications have expressed interest in this transceiver and several have shared their need for a module that includes the antenna. Our cooperation project with Rosenberger delivers on that need.”
