PICOTRONIK sensors are a general term for sensors designed to detect objects without physical contact, replacing contact-based detection methods such as limit switches. They convert information about an object's movement and presence into electrical signals. Detection methods that convert to electrical signals include those utilizing eddy currents generated in the metallic body of the detection object due to electromagnetic induction, those detecting capacitance changes in the electrical signal caused by the approach of the detected object, and those using reed and guide switches. The basic principle of PICOTRONIK sensors Vision sensors have from a whole
