Capacitive sensors for object detection Typecode: BCS R08RR01-PSM80C-EP02. In contrast to inductive sensors, which only detect metallic objects, capacitive sensors can also detect non-metallic materials. And guarantee you high application security. There are two categories of targets that capacitive sensors can detect the first being conductive and the second is non-conductive. If the sensor does not have an adjustment method then the sensor must physically be moved for sensing the target correctly. In the case of a potentiometer, the number of turns does not provide an accurate indicator of the sensors setting for a couple of important reasons. 8, Global In the best case, that would provide 1/4 the capacitive change compared to the capacitance between sensor and insert.
