Chinese name: Capacitive proximity switch& nbsp;   Reason: The change in the dielectric constant of a capacitor& nbsp;   Path: SBN-U1-QK2 capacitive proximity switch with controllable switch on/off function. The sensing surface of the 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. SBN-U1-QK2 capacitive proximity switch capacitive type: capable of detecting 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.

Inductive proximity switch working principle: It belongs to a position sensor with switch output, which is composed of an LC high-frequency oscillator and an amplification processing circuit. When a metal object approaches the oscillating induction head that can generate electromagnetic fields, eddy currents are generated inside the object. This eddy current acts on the proximity switch in reverse, causing the oscillation ability of the proximity switch to decay, and the parameters of the internal circuit to change, thereby identifying the presence of metal objects approaching and controlling the on or off of the switch. The object that this proximity switch can detect is a metal object. 2. Working principle of Hall switch: Hall switch belongs to this type of active magneto electric converter device. It is made using integrated packaging and assembly technology based on the Hall effect principle. It can easily convert magnetic input signals into electrical signals in practical applications, while also meeting the requirements of easy operation and reliability in industrial applications. 3. Working principle of capacitive proximity switch: It also belongs to a position sensor with switch output. Its measuring head is usually one of the plates that make up the capacitor, and the other plate is the object itself. When the object moves towards the proximity switch, the dielectric constant of the object and the proximity switch changes, causing the circuit connected to the measuring head to also change, thereby controlling the on and off of the switch. The detection object of this proximity switch is not limited to metal conductors, but can also be an insulating liquid or powder object when detecting lower dielectric constantsε When adjusting an object, the potentiometer (located at the back of the switch) can be adjusted clockwise to increase sensing sensitivity. Generally, the potentiometer is adjusted so that the capacitive proximity switch is in the 0.7-0.8Sn position.
