Dual-axis pneumatic cylinder usually refers to a pneumatic actuator with two cylinder drive shafts, if the working system has a position feedback requirements will usually need to use the magnetic ring, today's article is also centered on the role of the dual-axis pneumatic cylinder and the advantages of the magnetic ring to start the introduction.
Magnetic rings in dual-axis pneumatic cylinders are mainly used for position detection and limit control. The magnetic ring is used in conjunction with the magnetic sensor inside the pneumatic cylinder to detect the displacement of the piston of the pneumatic cylinder in real time, which helps the control system to determine whether the pneumatic cylinder has reached a certain position or the end of the stroke.
Integral ring magnet for pneumatic cylinder
Magnetic rings can be used to set the start and end positions of pneumatic cylinders. When the piston approaches a certain limit position, a change in the magnetic ring triggers a sensor that controls the pneumatic cylinder's action to stop or reverse.
Turning to the advantages of magnetic rings, the main ones are non-contact measurement, which greatly reduces wear and maintenance costs. High sensitivity, providing accurate position feedback. Resistant to harsh environments (oil, water vapor), suitable for a variety of industrial environments.
This structure is widely used in automation, robotic arms, robotics, CNC equipment and other areas where the position of cylinders needs to be precisely controlled.
Currently, the magnet material used in most pneumatic cylinders is ferrite because of its low cost and corrosion resistance, although the magnetic force is slightly weaker, it is sufficient for position detection. NdFeB magnets are strong and suitable for situations where a stronger signal is required, but may require surface treatment to prevent corrosion.
