JOINT TORQUE SENSOR

Rotary-joint torque feedback

JTorq Motus™ Robot Joint Torque Sensor

A torque sensor that measures the output torque of robot motor joint modules, providing real-time data for closed-loop torque control, overload protection and condition monitoring. It offers a multi-range design, low drift, good repeatability and standardized interfaces, and suits integrated joints, servo drives and test platforms.
