ATI Omega F/T Sensor
The ATI Omega family is a line of six-axis force/torque (F/T) sensors that measure three orthogonal forces (Fx, Fy, Fz) and three torques (Tx, Ty, Tz). Each transducer body is EDM wire-cut from a single block of high-yield-strength stainless steel, delivering very high structural strength and overload margins (approximately 4× to 25× the rated capacities depending on the model and calibration).
Models in the family
The Omega line includes Omega85, Omega160, Omega190 and the newer Omega191 (improved customer interface, drop-in replacement for Omega190). Each model is available in several calibrations covering different load ranges and resolutions, from around 105 lbf (Omega85) up to several thousand lbf on the larger models. Through-hole options are available on selected models.
Construction and signal
Omega transducers use silicon strain gages whose signal is approximately 75× stronger than conventional foil gages. After on-board amplification this yields a high signal-to-noise ratio and near-zero noise distortion. Omega sensors interface with ATI data acquisition systems including Net F/T, NetBox/NetCAN, EtherNet/IP, EtherCAT, DeviceNet, CANopen, RS-485 and the analog F/T Controller.
Environment and IP protection
Depending on the model and ordering option, the Omega sensors are available in IP60 (dusty environments), IP65 (water-spray) and IP68 (10 m fresh-water submersion) versions. Typical applications include industrial robotics, robotic grinding and polishing, force-controlled robotic assembly, prosthetics research, product testing, friction stir welding, and research in humanoid robotics and manipulation.

Which group ATI Omega F/T Sensor belongs to and how it is built
A Force Torque Sensor measures linear forces and rotational torques at a single measurement point. In robotics, it is particularly important in manipulators, robot wrists, grippers, and human–robot collaboration systems. It enables force control, contact detection, load monitoring, and improved safety and manipulation precision. Sensors of this type are widely used in assembly, laboratory, and research applications.
