Description

FlexiForce™ A201 Sensor

Digikey Mouser

A201 sensors are trimmable and have a 3-pin male connector. 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, versatile force sensor can be modified by changing the drive voltage and adjusting the resistance of the feedback resistor (see "How to Adjust the Force Range" within the Electronics tab on the left).

Tekscan Recommends Using an Op Amp Circuit

If your application cannot allow an Op Amp Circuit, consult the FlexiForce Integration Guide, or contact a FlexiForce Applications Engineer. If you prefer to build your own electronics, we recommend using a circuit similar to the diagram below. This will provide linear data, making it easier to calibrate the sensor.

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.
