The Shanghai Q30M-W10H capacitive proximity switch model capacitive proximity switch can detect metals, non-metals, glass, liquids, etc. Its detection distance is closely related to factors such as the conductivity constant, water content, and object volume of the detected object. When using, it is necessary to ground the metal object, otherwise the switch will have a false effect. The tail is equipped with a sensitivity adjuster, which can adjust the distance. Proximity switch, also known as contactless proximity switch, is an electronic switch quantity sensor. When the metal detection body approaches the area of the switch, the switch can quickly issue electrical commands without contact, pressure, or sparks, accurately reflecting the position and travel of the moving mechanism. If used for general travel control, its positioning, operating frequency, service life, ease of installation and adjustment, and adaptability to harsh environments cannot be compared to general mechanical travel switches. The sensing surface of the Hubei Q30M-W10H capacitive proximity switch model switch function capacitive sensor is composed of two concentric metal electrodes, which are equivalent to the electrodes of a non wire wound capacitor. The surfaces a and b of the electrodes are connected to the feedback branch of a frequency oscillator, and the adjustment of the oscillator should ensure that it does not oscillate when the surface is free< When an object approaches the surface of the sensor, it enters the electric field in front of the electrode surface and causes a change in the coupling capacitance. The oscillator begins to oscillate, and the amplitude of the oscillation is recorded by an evaluation circuit and converted into a switching command.
