Force/Torque Sensor Selection Guide
Choose a sensor in the order that matters for integration — start from the load you must measure, then narrow by protection, resolution, speed, interface, mounting and environment.
How to choose — in order
1 · Measurement range
The first decision. Pick the smallest range that still covers your peak load — smaller range means finer resolution.
2 · Overload protection
Headroom above peak load protects the sensor against impacts and mishandling.
3 · Noise-free resolution
The smallest force change you can resolve cleanly — critical for fine assembly and contact tasks.
4 · Sampling frequency
Higher rates capture fast contact events and enable tight force-control loops.
5 · Signal type / interface
Analog vs digital, and the bus your controller speaks — EtherCAT, CAN or USB.
6 · Mounting
Wrist-mounted six-axis for arm-level force control; fingertip/tactile for in-hand contact.
7 · Environment
Operating temperature and IP rating for your shop-floor or lab conditions.
Choose by application
| Application | Recommended |
|---|---|
| Fine assembly / insertion | High-resolution, small-range six-axis F/T |
| Heavy-duty grasping / handling | Large-range six-axis F/T with strong overload protection |
| End-effector force control | Six-axis wrist sensor + optional fingertip tactile |
| Tactile / slip perception | Finger / robotic tactile sensor |
