Abstract
The utility model discloses an ultra-thin conductive plastic angle and displacement sensor. The ultra-thin conductive plastic angle and displacement sensor comprises a double-track resistor substrate, a positive pole leading-out terminal, a negative pole leading-out terminal, a signal output end, a shaft liner, an electric brush, a shell and a shaft. The shaft is arranged in the shell. One end portion of the shaft is connected with the shaft liner, and the other end portion of the shaft extends out of a shaft installation hole of the shell. The double-track resistor substrate is connected with the shell. The positive leading-out terminal, the negative pole leading-out terminal and the signal output end are respectively arranged on the double-track resistor substrate. The shaft liner is connected with the electric brush. The electric brush moves on the double-track resistor substrate along with rotation of the shaft. The double-track resistor substrate is adopted, the leading-out terminals and the double-track resistor substrate are connected as an overall structure, and therefore the overall structure of the sensor is simplified, the overall product thickness is reduced, and the sensor is suitable for being used in fields with limited space.
