Electrostatic Capacitance Torque Sensor
This is a sensor to detect and control torque generated at revolving motion of various kinds of robot and automated assembly machines.
Because of adoption of electrostatic capacitance system, we realized simple construction other torque sensors with the conventional strain gauge. Our model enables reduction of the number of parts, great cost reduction and freely designing corresponding to needs.
- Simple construction, light weight & low cost due to adoption of electrostatic capacitance system
- Due to built-in micro computer, outer module for corrective process is not required

Example of Adoption
YASKAWA 6-axis robot, MOTOMAN-HC10DT／MOTOMAN-HC20DT (ESTORQ is equipped in every joint)
MOTOMAN-HC10DT / MOTOMAN-HC20DT is a collaborated robotic design by Yaskawa, that is designed to work side-by-side with people. Both types have adopted the I-PEX torque sensor, ESTORQ® as the joint shaft torque sensor.
Because ESTORQ® is equipped to detect external force, it will automatically stop when the robot detects interference. An important function of the collaborative robot is its ability to work side-by-side with people.
Torque sensor series
Electric hand “ES-Hand”
The ES-Hand is an electric hand that can be used as an end effector for robotic arms, equipped with an electrostatic capacitance torque sensor "ESTORQ." It has a wide gripping force range and can even grip soft materials like pudding.
"ES-Gripper," the gripper for connector automatic mating robots
The ES-Gripper is a gripper that can be used as an end effector for robotic arms equipped with the electrostatic capacitance torque sensor "ESTORQ." Automatic insertion and mating of connectors are possible.
