SCHUNK FT-AXIA Force Torque Sensor Review: Specs, Price and Applications
The SCHUNK FT-AXIA is a compact, rigid six-axis force/torque sensor with the electronics integrated into the sensor body. It measures forces and moments in all six degrees of freedom and outputs processed data directly over industrial Ethernet, with EtherNet or EtherCAT versions available.
Two calibrations are stored in the sensor, so two measuring ranges can be selected through a web interface. A software module provides plug & work integration with KUKA and Universal Robots, and an optional LED version displays the sensor status at the flange.
Quick Verdict
A cost-efficient, easy-to-integrate sensor for collaborative and light industrial robots. The dual calibration and direct Ethernet output reduce both hardware and commissioning effort.

Design and Operating Principle
FT-AXIA integrates signal conditioning and communication into the sensor, removing the separate interface box that older force sensors needed. The output is already converted to forces and moments, which simplifies the controller software.
Dual calibration addresses a classic trade-off. A low range gives fine resolution for delicate tasks such as hand guiding or light assembly, while a high range covers heavier tools or process loads. Switching via the web interface lets one sensor serve both modes.
The rigid body keeps tool deflection low, which is important for precise positioning when the sensor sits between the robot and a gripper or spindle.
Integration and Selection
Check the combined tool mass and process forces against both calibration ranges and choose the version that matches the robot's fieldbus. On KUKA and UR robots, install the software module for direct integration.
Route the M8/M12 sensor cable and RJ-45 data line along the robot dress pack with enough slack for wrist motion, and verify zeroing and tool-load compensation in the robot program.

Who Should Consider the SCHUNK FT-AXIA Force Torque Sensor?
FT-AXIA fits cobot users and integrators who want six-axis force sensing with minimal hardware and fast integration, especially on KUKA and Universal Robots platforms.
Price and Availability
Price: Request a quote. SCHUNK prices the FT-AXIA by size, options and quantity, so the final figure depends on the exact configuration. Budget for the complete tooling package, including fingers or adapters, mounting, air or electrical connections and commissioning time, rather than the module alone.
