Product Description


The inductive surface of the capacitive proximity switch is composed of two coaxial metal electrodes, which form a capacitance and are connected in RC oscillation circuit. When the power is switched on, the RC oscillator does not oscillate. When a target is close to the sensor's inductive surface, the capacitance increases and the oscillator begins to oscillate. Through the processing by the post circuit, it is converted into the switching signal, thereby achieving the purpose of detecting the existence of objects. The capacitive sensor can detect metal objects, and also can detect non-metal objects. For metal objects, the maximum movement distance can be obtained. For non-metal objects the movement distance depends on the material's permittivity, the bigger the material's permittivity, the larger the movement distance can be obtained.


It can detect different materials such as metal, plastic, liquid and so on;  Different materials in vessel can be detected through non-metal tube wall;  Equipped with potentiometer to conduct sensitivity adjustment function.


Detect the liquid level from the sideways of the outside of the bottle ; Check whether the worktable is rotated in place;  Detection of objects in package Detection of bottle cap.
