What is the overload capacity of the FT-300-S?

Context

Before using the FT‑300‑S force/torque sensor, it’s crucial to understand its overload thresholds. This helps prevent damage and ensures accurate readings in your robotic applications.

1. Measuring Range (Nominal Capacity)

• Force: ±300 N

• Torque: ±30 Nm

These are the maximum values the sensor can measure accurately without signal saturation.

2. Overload Capacity

The sensor can physically tolerate loads significantly beyond its nominal range without immediate failure—but only up to a point.

• Overload capacity (combined equivalent): 1500 N, or 500% of the measuring range

• Applies across all force and torque axes

⚠️ Exceeding this overload capacity will cause permanent damage to the sensor

3. Combined Load Calculation

Use the following formula to ensure your application stays within the safe limit:

• Each value is in N (force) or Nm (torque)

• The total must stay under 5, representing 500% overload

Conclusion

To keep your FT‑300‑S in good condition:

• Stay within the 300 N / 30 Nm nominal range for accurate readings

• Ensure combined loads never exceed the overload threshold using the provided formula

• Understand the risks of operating near or above the limits
