To understand how the magnetic switch works, we must first understand what the magnetic switch is used for. Take the cylinder as an example. On the cylinder side, the main function of the magnetic switch is to check the operation of the piston of the cylinder. When the magnetic ring of the cylinder moves slowly close to the magnetic induction switch, the magnetic reed of the magnetic switch will be induced, thus causing the electric shock to close and generate a signal. When the magnetic ring of the cylinder leaves the area of the induction switch, the magnetic reed loses the induction magnetism, which causes the electric shock to be disconnected and no signal will be generated. In this way, the position of the piston of the cylinder can be checked and the corresponding action of the solenoid valve can be controlled.
Magnetic switch features: the existence of each product is inseparable from its characteristics, formally because the characteristics of each product is the point we need in life, benefit at home use, so it will be always there. So what are the characteristics of magnetic switches? First about the magnetic switch material, PVDF, PP material, the benefits of this material is able to withstand strong acid, strong alkali place; And the terminal box of magnetic switch, compared with other switch terminal box, is relatively complete, aluminum alloy, plastic, stainless steel and riot series, safe and reliable, solid and solid; The contact capacity of magnetic switch is 30W/200VDC SPDT and 50W/250VAC SPST. Multiple nodes can be installed, cost saving, easy to install.
Other series of products: magnetic switch and other switch, magnetic switch also has its own other products series, general classification on the presence of contact, which has two kinds of nodes, its work is not the same, so the two kinds of the use of the magnetic switch are also different, there are some market above door magnetic switch, proximity switch, are all belong to a kind of induction switch, and the magnetic switch because of magnetic field control, so is the induction switch. In addition, there is a kind of magnetic switch, it is sealed in plastic pipe or metal, to set up more, a little spring switch, the pipeline, internal mount magnet spherical floating ball, using fixed float ring, control switch and float to the corresponding position, to float to float in a certain scope, using the floating ball magnetic to attract the contact spring switch, so, magnetic switch to produce action that open and close.
Magnetic switch performance comparison: the switch performance comparison, small series of the use of no contact and contact magnetic switch performance comparison. In terms of leakage current, 2-wire type is below 1mA and 3-wire type is below 100ma. The operation time per second is less than or equal to 1. Its service life is long. Magnetic switch with contact, no leakage current, operation time of 1.2ms, service life of only tens of millions of times, impact resistance of around 300/2s. Both can be used in relays, integrated circuits, and small solenoid valves.
Magnetic switch installation precautions: because magnetic switch is a dangerous product, so the non-operator is not allowed to touch. There are many things to note about magnetic switches, especially for products in this kind of high voltage circuit, be careful. In the installation process, the surrounding air can not have still material, in the installation, can not let the magnetic switch received a large impact force; When installing, do not connect with other high-voltage lines; Such as the installation of two magnetic switch, the distance between the better than 3mm, this is also for the sake of safety.
