[0002] A proximity sensor is a general term for sensors that replace contact detection methods such as limit switches and are used to detect objects without contacting them. It can convert the movement information and presence information of the detected object into electrical signals. In the detection method of converting into electrical signals, it includes the method of using eddy currents generated in the metal body of the detected object caused by electromagnetic induction, the method of detecting the capacitance change of electrical signals caused by the approach of the detected object, and the method of using a reed and a guide switch.
