Gansu D-T991 Benan Mining Magnetic Proximity Switch Magnetic Switch Application Magnetic switches are mainly used to control the action of industrial machinery, with a speed ratio range of 1:1 to 1:150; The assembly of the overall size in a small space, the transmission shaft and gear drive shaft are made of stainless steel materials, and the gears and drive bushings are made of self-lubricating thermoplastic materials. All materials and components have good wear resistance, and the equipment has good waterproof and dustproof performance. Magnetic switches are mainly used to control the operation of industrial machinery such as cranes, with a speed ratio ranging from 1:1 to 1:9400; There are 2, 3, 4, 6, 8, 10 or 12 limit switches installed, as well as pointed cam PRSL7140PI. According to user requirements, we can provide components and speed ratios. Make an order. The speed ratio is 1:9400. All materials and parts are corrosion-resistant, waterproof, and dust-proof. The D-T991 intrinsically safe mining magnetic proximity switch cylinder magnetic switch is used to detect the position of the cylinder piston, that is, to detect the movement stroke of the piston. It can be divided into two types: contact type (contact magnetic reed type) and contactless type (contactless electric crystal type). The contact type magnetic reed tube has mechanical contacts composed of two magnetic reed tubes, which are universal for AC and DC power supplies. When the magnetic ring moving with the cylinder approaches the induction switch, the two magnetic rings of the induction switch are magnetized, causing the contacts to close and generating a signal; When the magnetic ring leaves the magnetic switch, the tongue loses excitation, the contact opens, and the signal disappears. This can detect the piston position of the cylinder and control the corresponding solenoid valve action. Non contact electrical crystal type - NPN and PNP types can only be used for DC power supply, mostly three wire type; NPN and PNP should pay attention to the differences in wiring when using relay circuits; When selecting PLC, attention should be paid to the correct selection. The contactless induction switch is fundamentally different from the contact type induction switch in terms of structure and principle. It sends control signals by controlling the internal transistors. When the magnetic ring approaches the induction switch, the transistor conducts and generates a signal; When the magnetic ring leaves the magnetic switch, the transistor turns off and the signal disappears.
