Capacitive proximity sensor) is a sensor (sensor) another type used for detecting objects without touching. Object detection using all kinds of both metals and nonmetals such as glass, water, wood, plastic, paper, and so on.(dielectric, constantK) of the object, the proximity sensor capacitor has the characteristics of the shape. And structure similar to a proximity sensor induction (inductive proximity sensor), but the working principles of different
.Proximity sensor capacitor. Work based on the principle of value change of capacity. When the target objects moving near electric field at birth by active electrodes เอิทธ์ and electrode.The size and shape of an object and the type of the target object (dielectric constant), when the charge capacity change until the other one, which is equal to the resistance to adjust it at the beginning.Call state this happened that R - C, the resonance (R - C Resonance) components and functions of พร็อก ซิมิตี้ sensor capacitor.
