Six-Axis Force Torque Sensors: Robot Integration Guide
A six-axis force torque sensor measures three forces and three moments about a defined coordinate system, so selection must consider every load component and its lever arm. Choosing only from the largest expected axial force can leave the moment axes undersized, while choosing excessive range can sacrifice useful resolution for a precision task. Build the RFQ from realistic continuous, transient and accidental load cases. Ask suppliers to return the exact range configuration, calibration report format, coordinate origin, signal chain, interface, sampling behavior and mechanical integration rather than a family-level datasheet alone.
How to shortlist
Six-component load case
Estimate positive and negative Fx, Fy, Fz, Mx, My and Mz for normal operation, transients and setup errors. Include moments created by tool and workpiece offsets.
Range and headroom
Select working ranges above credible maximum operating loads without treating overload capacity as normal capacity. Ask whether ranges are symmetric and whether combined loading changes limits.
Accuracy and crosstalk
Compare nonlinearity, hysteresis, repeatability and crosstalk using the same full-scale definitions. Relate them to the smallest process force or torque that must be resolved.
Noise, resolution and bandwidth
Specify required control-loop or measurement bandwidth, sample rate and allowable noise after filtering. A high output rate does not by itself establish usable dynamic performance.
Decoupling and signal chain
Confirm whether decoupling is performed in the sensor, interface box or host, how the matrix is supplied, and whether analog amplification or digital conversion is included.
Mechanical envelope and stiffness
Check flange patterns, through-hole needs, height, mass, coordinate origin and structural stiffness. Include adapter plates when calculating stack height and load moments.
Calibration and drift
Request calibration scope, traceability, per-axis results, temperature behavior, zeroing method and recommended recalibration interval for the application.
Communication and synchronization
Select analog, Ethernet, EtherCAT, CAN, CAN FD, serial or USB according to the controller, deterministic timing, cable run, synchronization and diagnostic requirements.
