FlexiForce Tekscan A101 Sensor

The FlexiForce A101 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 FlexiForce A101 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

Applications:

1. Testing and Measurement Equipment
2. Embedded Electronics
3. OEM Development Kit
4. Consumer Electronics
5. Multimeter

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

The 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 25 lb (111 N))

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)*

* Force reading change per degree of temperature change = 0.36%/ºC (±0.2%/ºF)
