In addition to detecting the position and movements of a person, the SC1240 Series radio-wave ranging sensor’s high-precision sensing and built-in signal processing circuits utilize a 6.8GHz (57.1 ~ 63.9GHz) wide band. This enables the detection of minor movements as positional information, making the device ideal for advanced applications such as tracking human movements and operation by gestures.

The broadband 60GHz radio-wave range-finding sensor with built-in range-finding and angle-calculating signal processing circuit is offered as the industry’s first. It is based on the company’s experience and knowledge accumulated through years developing millimeter-wave radio communication LSIs and 24GHz radio-wave range-finding sensors.

The highly integrated SC1240 series uses 3D position information without the need for high frequency or advanced signal processing technology. It includes multiple antennas, wireless circuitry, A/D converters, FIFO memory, SPI interface, a high-performance sequencer that flexibly changes the duty cycle and controls power consumption, and a signal processing circuit for high-performance distance measurement and angle calculation.

It also provides an autonomous activation function. These features allow users to easily obtain the height and positional data on the X, Y and Z planes for detection of multiple people, gesture without contact, and other high-precision sensing. Following the debut of its SC1240AR3, the company says that it will continue to develop products that meet customer needs and applications.

Sample shipments are scheduled for Q2 2022, and mass production in Q1 2023.
