China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Pneumatic cylinder, which mainly refers to the use of compressed air as a driving force of a device components, according to the actual need for different can be divided into magnetic and non-magnetic, with magnetic will come with a magnet (ring or half-ring), today the courage magnet manufacturers small Fu will talk about the magnetic cylinder with magnetic magnet material, shape, installation location, common size and so on.
What is the purpose of the built-in magnetic ring in a pneumatic cylinder?
Pneumatic cylinders with magnetic rings can be equipped with magnetic induction switches or magnetic induction sensors on the outside of the cylinder to detect the position of the cylinder piston, and then some other control programs, the built-in magnetic ring in the cylinder is mainly used to work with the magnetic switches on the outside of the cylinder, which is mainly used for sensing the position of the piston, and when the piston is moved to the position of the magnetic switches, the magnetic switches will be triggered and signal to the control system in order to perform the next action.
Where is the magnet ring located in a pneumatic cylinder?
The vast majority of magnetic rings are mounted on the piston and move as the piston moves. Magnetic switches can be mounted at the end of travel or anywhere in the middle of travel.
What are the main materials of magnets in pneumatic cylinders?
There are mainly injection molded ferrite, bonded neodymium iron boron, flexible rubber magnets.
Shape of magnets in pneumatic cylinders;
Mainly ring shaped (some with notches), half ring shaped (set of 2)
Dimensions of magnet rings commonly used in pneumatic cylinders;
The size of the magnet ring used in pneumatic cylinders will vary according to the specifications of the cylinder, the thickness is mostly in 4mm, 5mm, the following dimensions for reference.
Pneumatic cylinder diameter 20mm, magnet ring 19.5*12*4mm
Pneumatic cylinder diameter 25mm, magnetic ring size D24.5*16x4mm
40mm cylinder pneumatic diameter, magnetic ring 39.5*24*4mm
50mm cylinder pneumatic diameter, magnetic ring 49.5*35*5mm
100 pneumatic cylinder diameter size, magnetic ring 99.5*85*5mm
