Description

FlexiForce™ A301 Sensor

Volume discounts icon

The A301 is optimized for high volume manufacturing and ideal for embedding into products and applications.

The sensors are available in three force ranges: Low 4.4 N (0 - 1 lb), Medium 111 N (0 - 25 lb) and High 445 N (0 - 100 lb)*. The force ranges stated are approximations. The dynamic range of this small 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. For an alternative to the recommended circuit, see the Related Electronics tab.

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)††

Acceptance Criteria: ±40% sensor-to-sensor variation

 

All data above was collected utilizing an Op Amp Circuit. If your application cannot allow an Op Amp Circuit, consult the FlexiForce Integration Guide, or contact a FlexiForce Applications Engineer.
