The magnetic switch of the pneumatic cylinder is a commonly used sensor, which can realize the control of the switch by detecting the change of the magnetic field. This switch has the advantages of high sensitivity, fast response, and strong reliability, so it has been widely used in industrial automation control.
The working principle of the pneumatic cylinder magnetic switch is to use the effect of the magnetic field. When a magnetic substance approaches the switch, the magnetic field will change, thus changing the state of the switch. This kind of switch is usually composed of magnetic material and pneumatic components.
When the magnetic material is close to the switch, the magnetic material will be affected by the magnetic force, so that the pneumatic components will move, and finally realize the control of the switch.
The pneumatic cylinder magnetic switch has many advantages. First, its sensitivity is very high and it can detect small changes in the magnetic field, so it can be used to detect very small objects. Secondly, its reaction speed is very fast, and the control of the switch can be realized in a short time, thereby improving the production efficiency. In addition, it also has the characteristics of strong reliability, can work normally in harsh working environments, and is not easily affected by external interference.
The pneumatic cylinder magnetic switch has a wide range of applications, it can be used in mechanical processing, automated production lines, logistics and other fields. For example, in mechanical processing, the pneumatic cylinder magnetic switch can be used to detect the position of the workpiece, so as to realize automatic processing; in the automatic production line, it can be used to detect the arrival and departure of items, so as to realize automatic control; It can be used to detect the position and movement status of goods, so as to realize logistics automation.
Features: The magnetic switch is used to detect the stroke position of the pneumatic cylinder. It is not necessary to set up a mechanically controlled valve (or stroke switch) and its mounting frame at both ends of the stroke, and it is not necessary to set a bumper at the end of the piston rod, so it is easy to use and compact in structure. High reliability, long life, low cost, fast switching response time, so it is widely used.
Mount the magnetic switch on the outside of the pneumatic cylinder barrel of the air pneumatic cylinder. The pneumatic cylinder can be various types of pneumatic cylinders, but the pneumatic cylinder barrel must be made of materials with weak magnetic permeability and strong magnetic isolation, such as duralumin, stainless pneumatic cylinder, brass, etc.
A magnetic ring with a permanent magnet (rubber magnet or plastic magnet) is mounted on the piston of the pneumatic cylinder. When the magnetic ring moving with the piston approaches the switch, the two reeds of the reed switch are magnetized and attract each other, and the contacts are closed; when the magnetic ring moves away from the switch, the reeds lose their magnetism and the contacts are disconnected. When the contact is closed or disconnected, an electric signal is sent out (or the electric signal disappears), and the corresponding solenoid valve is controlled to complete the switching action.
