FlexiForce A101 Mini Force Sensor is our smallest sensor optimized for high volume manufacturing and ideal for embedding into products. The 2-pin sensors are currently our smallest standard sensor.

The sensors can measure up to 10 lbs.* The dynamic range of this mini force sensor can be modified by changing the drive voltage and adjusting the resistance of the feedback resistor

How to Adjust the Force Range:

In order to measure higher forces, apply a lower drive voltage (-0.5 V, -0.25 V, etc.) and reduce the resistance of the feedback resistor (1kΩ min.) To measure lower forces, apply a higher drive voltage and increase the resistance of the feedback resistor.

Sensor resistance measured 20 seconds after applied load

Sensor was not attached to any drive circuitry

Typical Performance:

• Linearity (Error) : < ±3% of Full Scale (Line drawn from 0 to 50% load)
• Repeatability : < ±2.5% (Conditioned Sensor, 80% of Full Force Applied)
• Hysteresis : < 4.5 % of Full Scale (Conditioned Sensor, 80% of Full Force Applied)
• Drift : <5% / logarithmic time (Constant Load of 111 N (25 lb))
• Response Time : < 5 µsec (Time required for the sensor to respond to an input force; Impact load - recorded on Oscilloscope)
• Operating Temperature : -40°C - 60°C (-40°F - 140°F)
• Acceptance Criteria : ± 40% sensor-to-sensor variation
• Durability: ≥ 3 million actuations (Perpendicular load, room temperature, 22 N (5 lb))
• Temperature Sensitivity : 0.36%/°C (± 0.2%/°F) (Conductive heating)
