Product Advanced Technology for Human

RFT series is a capacitive type 6-axes force/torque sensor with the lower price/performance ratio for the use with collaborative robots and industrial robots. It has an innovative structure design and a robust calibration algorithm to achieve both of cost competitiveness and reliable performance. It provides users with various interface options for communication with their robots or devices. It was primarily designed to resist against an external impact or an excessive load. It is also temperature compensated for the use in various environments.

Customized models have been developed for specific business partners including collaborative robot makers. We are ready to cooperate with potential partners. The customization service includes from a specific mechanical interface to an optimized model development so that our sensor technology can fit into your application.

Many customers all over the world have been using our sensors in a wide range of automation and research applications.
RFT series can monitor processes quality or versatilely handle workpieces with robot arms in production lines of various products- smartphone, secondary battery, and so on. They also help collaborative robots to accomplish delicate tasks through the safer and easier operation. They are reliable enough for the use in medical or rehabilitation devices, light enough for the use on a drone. Most of all, you can enhance your system a step further by monitoring or controlling force/torque with our high performance sensors.
