The two-wire magnetic switch has one power line and one signal output line, making the wiring simple. It is commonly used in simpler applications, such as equipment status detection and limit switches.
The three-wire magnetic switch has one power line, one ground line, and one signal output line. It is used in applications that require complex signal processing, such as transmitting status information and equipment measurement.
Contact-type magnetic switch: Outputs signals through physical contact (contact switch), with a simple structure and low cost.
Non-contact magnetic switch: Outputs signals by sensing magnetic field changes, suitable for applications with high-frequency signal vibrations, and is more expensive.
Two-wire switch:
The brown wire connects to the positive terminal of the power supply, the blue wire connects to the input terminal of the load, and the other terminal of the load connects to the negative terminal of the power supply.
Three-wire switch:
The brown wire connects to the positive terminal, the blue wire connects to the negative terminal, and the black wire connects to the input terminal of the load.
The magnetic switch can detect the position of the magnetic cylinder piston, helping to adjust the stroke of the cylinder and achieve automation control.
The key parameters of a cylinder are: bore diameter, stroke length, working pressure, and mounting type.
Different types of cylinders have different bore diameters. The bore diameter of mini cylinders is typically between 8-32mm, standard cylinders typically range from 32-125mm, and large bore cylinders generally have a bore diameter of 160mm and above.
Main body: Aluminum alloy or stainless steel
Piston rod: Chrome-plated carbon steel or stainless steel
Internal seals: TPU (Thermoplastic polyurethane) or NBR (Nitrile rubber)
No. When the piston rod bears lateral forces, it will cause the cylinder to operate unstably and significantly reduce its service life. If lateral forces must be encountered, please choose a cylinder with a guide rod.
High and low temperature environments: Choose seals that are resistant to high or low temperatures.
Dusty environments with water droplets and oil spots: The piston rod should be equipped with a telescopic protective cover.
Strong magnetic environments: Choose cylinders with switches that are resistant to strong magnetic fields.
0.1MPa≈1bar≈1kgf≈1atm≈14.5psi
Cylinders typically cannot withstand axial force. Applying axial force can cause unstable operation, reduce sealing performance, and lower movement accuracy. In severe cases, it may even directly damage the cylinder.
Cylinders with guide rods can withstand some axial force, but it is still not recommended to use them specifically to bear axial force.
A: The automatic internal drain operates whenever liquid has accumulated in the filter bowl and a tool or valve is cycled, causing a momentary pressure drop of 2 psi or more. It also drains whenever the air supply is shut down and exhausted, overnight or for the weekend. Manual draining of filters is often overlooked in the industrial environment and M/P recommends that all filters be ordered with automatic drains.
A: The industrial environment will control the useful life of the elements. The dirtier the environment, the shorter the lifespan.
A: Master Pneumatic has just introduced our new SENTRY Acetal-Body Water Pressure Regulators (R13, R14 Models), and also our new MINIATURE Brass Body Water Pressure Regulators (R53B, R54B Models). Consult with factory concerning regulator compatability with liquids other than water or oil.
A: Standard regulators are designed for compressed air usage but may be used on nitrogen, argon, and other inert gases, within specified ranges. Regulators with neoprene seals are available for use with CO2. Regulators must never be used with flammable gases, and the factory must approve oxygen applications.
A: To set the regulator, turn the adjustment knob counter-clockwise to lower the line pressure below the required P.S.I. then, increase the pressure by turning the adjusting knob clockwise untill the desired pressure is reached.
A: Typically, oil with a viscosity of 150 - 1200 S.U.S. will be acceptable. However, because of the wide variety of oil types available, please consult our factory.
