German connectivity specialist Rosenberger and Swiss-based STMicroelectronics have developed a contactless connector for ultra-reliable, short-range, point-to-point full-duplex data exchanges in industrial and medical applications.

Rosenberger’s contactless connector, the RoProxCon, employs 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 is designed to provide reliable, point-to-point, high-data-rate transmission of up to 6.25 Gbps over distances of a few centimetres – at exceptionally low power. Operating over an extended temperature range of -40 to +105°C, the chip ST60A2 is designed for industrial markets. According to ST, the chip, with a 2.2 x 2.2 mm package footprint, is the smallest device available on the market with ultra-low power consumption of 70mW for a 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.”
