FlexiForce Tekscan A201 Sensor

The Flexi Force Tekscan A201 sensors are designed as a standard sensor perfect for embedding into different products. These  3-pin sensors are defined as standard sensors. This ultra-thin and flexible piezoresistive force sensor is available off-the-shelf in a variety of lengths for easy proof of concept. The A201 can be used with our test & measurement, prototyping, and embedding electronics, including the OEM Development Kit, FlexiForce Quickstart Board, and the ELF™ System ideal for prototyping and integrating into OEM applications.

These sensors can measure up to a force range of 4,448 N (1,000 lb). By changing the drive voltage and adjusting the resistance of the feedback resistor, the dynamic range of this force sensor can be modified. These ultra-thin sensors are ideal for a wide variety of applications such as non-intrusive force and pressure measurement.

In order to measure higher forces, highly recommended to apply a lower drive voltage (-0.5 V, -0.25 V, etc.). And thereby reducing the resistance of the feedback resistor (1kΩ min.). Whereas to measure lower forces, a higher drive voltage is applied and increase the resistance of the feedback resistor. The output of the A201 Sensor will be a function of many variables, including interface materials. Therefore, Tekscan recommends the user calibrate each sensor for the application. This 2-pin male square connector sensor provides an “active sensing area” of 0.375” diameter.

Due to its ultra-thin construction, flexibility, and force measurement ability, it is capable of measuring the force between almost any two surfaces. And is durable enough to stand up to most environments. FlexiForce Tekscan A301 Sensor features better force sensing properties, linearity, hysteresis, drift, and temperature sensitivity than other thin-film force sensors.
