Features [Excellent Materials]: The thin film ring pressure sensor is composed of environment nice polyester film, high conductivity material, and graphene pressure sensing material, with double sided adhesive design on the back for easy installation. This metal terminal interface can be directly soldered, has good oxidation opposition. [Thin Film Position Sensor]: This is a resistive type ring shapehigh sensitivity 160k impedance sensor. Connect V0 to ground, connect V+ to power supply positive pole, V1 is the output voltage of the sensor. [Product Advantages]: That resistive position transducer sensor provides excellent position sensing, with advantages such as quick response speed, long service life, stable performance, simple circuit principle, and convenient use. [Wide Application]: Our thin film sensor has a 160K impedance, and high sensitivity, and is suitable for various position sensing projects, such as potentiometers, gear switches, etc., with a wide range of applications. [Working Principle]: When there is no external pressure, V1 is in an open circuit state, and the output voltage V1 is 0; When there is pressure (20‑50g), the sensor triggers, V1 output voltage signal, when the pressure position moves from the left end of the sensor to the right end, V1 increases linearly from 0.2V+ to 0.8V+; After the pressure is removed, the sensor returns to the disconnected state, V1 voltage is 0.
