PD280 Datasheet | Novotechnik

Single-Turn Wirewound Potentiometers PD280 Series Special Features - very small dimensions - 200 x 103 movements - excellent linearity ±0.6% - very robust Precise potentiometer with a wirewound resistance element for control electronics and measuring applications. Remended for applications in harsh environments requiring a sealed potentiometer, the PD280 Series bines extraordinarilyhigh media resistance and robust engineering. Careful selection of materials and high-quality ponents ensure a constant and accurate angle measurement throughout the entire service life of the sensor. Special designs with other shaft dimensions and connections are available on request.
