High-speed contactless connector using wireless technology

Rosenberger’s contactless connector, the RoProxCon, leverages ST’s 60GHz RF transceiver, 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.

“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 6Gbps with complete rotational freedom.

“Much less expensive than alternative optical connectors and using much less power than other RF technologies, the RoProxConwill let innovators loose to create new applications,” said FolkeMichelmann, 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 withour RF chip is an outstanding example of the value of the technology,” added Laurent Malier, general manager at the RF & Communications Division, 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.”

The STMicroelectronics ST60A2 offers, point-to-point, high-data-rate transmission of up to 6.25 Gbps over distances of a few centimeters at low power. Operating over an extended temperature range of −40 to +105°C, the chip ST60A2 is suited to industrial markets. With a 2.2 x 2.2mm package footprint, the chip is the smallest device available on the market with ultra-low power consumption of 70mW for a reliable, completely contactless link.

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