How to read this table

Choose the measuring range from the forces and moments at the sensor's mounting point, not only the payload. A tool offset turns a modest force into a large moment, so check Mx, My and Mz against your tool length and acceleration.

Accuracy, nonlinearity, hysteresis and crosstalk are all stated as a percentage of full scale. A small percentage of a large range can still exceed the force you need to resolve, so pick the smallest range that covers your loads with margin.

Overload capacity protects the sensor during collisions and handling. If your application includes impacts, tool changes or manual guiding, compare the overload rating as carefully as the measuring range.

Interface and sampling rate determine how the sensor joins your controller. Digital outputs such as EtherCAT, Ethernet or RS-485 avoid a separate amplifier; analog versions need an acquisition system matched to the bridge output.

FAQ

Does a six-axis sensor need calibration after installation?

Manufacturers calibrate the sensor and provide a decoupling matrix or a decoupled digital output. You still need to zero the sensor in its mounted state and compensate the tool weight in your control software.

Which flange do I need for my robot arm?

Sensors are often supplied with adapter plates for common robot flanges. State your robot model and tool flange in the inquiry so the quotation includes the correct adapters and fasteners.

What is the difference between overload capacity and measuring range?

The measuring range is where the stated accuracy applies. Overload capacity is the load the sensor survives without damage; readings above the measuring range are not accurate even if the sensor is not damaged.
