Force-Torque Sensors

Omega331 Force/Torque Sensor

Omega331 Force/Torque Sensor, 40000 N / 6000 Nm Payload, Analog (+/-10V), 20-pin Lemo Connector

  • 6-Axis Force/Torque Sensing – Measures force and torque in all six degrees of freedom (Fx, Fy, Fz, Tx, Ty, Tz) with ranges up to 16000 N force and 2000 Nm torque, built for demanding industrial operations
  • Form Factor – Industrial-grade design with embedded electronics ensures broad platform compatibility with industrial platforms, with with the precision and reliability for surgical robotics
  • Analog Output (+/-10V) – Provides simple, real-time force and torque feedback compatible with most PLCs, controllers, and data acquisition systems.
  • Extremely-High Strength – EDM wire-cut from high yield-strength stainless steel. Maximum allowable overload values are 5.3 to 21.8 times rated capacities.
  • High Signal-to-Noise Ratio – Silicon strain gages provide a signal 75 times stronger than conventional foil gages. This signal is amplified, resulting in near-zero noise distortion.

Accuracy values vary depending on the axis of measurement. For detailed specifications and axis-specific accuracy data, please contact our sales team.
The effective sample rate is determined by the DAQ device in use. Specifically, the sensor sample rate equals the DAQ device’s total data rate divided by six (6) channels; one for each axis of force and torque. For additional assistance, please contact our sales or engineering team.
