Sensors are a means of providing feedback to a control system, so that the operating parameters of an application can be continually adjusted for optimal results. Pneumatic cylinder sensors can be used to measure various parameters. Their typical function in pneumatics is to detect the position of a pneumatic cylinder during its operation by means of proximity switches.
The phrase “pneumatic cylinder sensors” usually refers to position sensors, which are important in applications where the piston’s linear position is critical. Position feedback is provided by sensors mounted on the cylinder. It’s passed to the control system so that it can make necessary operational adjustments. Sensor proximity switches can be of an inductive mechanical type, but more common is a magnetic proximity switch and position transmitter connected to a control system.
The sensors deliver electrical signals via a transmitter, reporting the piston’s position to a control system. The feedback provided by position sensors offers an additional layer of security, ensuring that the piston is ideally placed to drive crucial applications.
Pneumatic cylinders also use other sensors, including those measuring airflow and pressure, but we’re focusing on position sensors. Of these, magnetic proximity sensors are probably the most common type. They’re mounted onto the cylinder body, where they can detect the magnetic field generated by the piston’s integral magnet. They indicate its proximity by relaying an ON or OFF signal to the control system.
The sensors can be mounted in various positions on the cylinder body to detect extension and retraction of the piston. They can also be mounted at one or more specific positions for more precise sensory input. The type of sensor you choose and the way they’re mounted will depend on whether you have a round or a rectangular (profile) cylinder body.

1. There are two ways of filter drainage: differential pressure drainage and manual drainage. Manual drainage must be discharged before the water level reaches the level below the filter element.
2. When adjusting the pressure, please pull up and rotate the knob before turning it, and press the knob for positioning. Rotate the knob to the right to increase the outlet pressure, rotate to the left to lower the outlet pressure. Pressure adjustment should be gradually and evenly adjusted to the required pressure value, should not be adjusted in one step.
3, the use of oil feeder: oil feeder using JIS K2213 oil (ISO Vg32 or the same oil). Please fill no more than eight full cups. The number 0 indicates the minimum amount of oil and 9 indicates the maximum amount of oil. Cannot rotate from position 9-0, must rotate clockwise. A. According to the pipe diameter, flow size, pressure regulation, filtration accuracy and other technical performance parameters, select the air components needed by the system; ?
B. The filter precision of air filter is 2um, 5um, 10um, 20um, 40um, 70um, 100um seven, according to the quality requirements of the air to choose the appropriate products;
C. When using the pressure reducing valve, try to avoid using the lower limit value of the pressure regulating range, choose the appropriate pressure reducing valve according to the requirements of the use of pressure;
D. Installation sequence: from the inlet end of the air source, connect the air filter, pressure reducing valve and oil mist at one time. The arrow direction on the component shell is the direction of air flow, and no reverse connection is allowed;
E. Air filter and oil mist must be installed vertically with the cup side down;
F. Once the oil mist is countercurrent, it will cause damage and danger to the internal parts, so it should be avoided;
G. During installation and connection, do not mix any impurities such as sealing tape and rust into the pipes.
Before choosing a type of solenoid valve, sufficient information about the application must be gathered. This guide describes the key parameters for solenoid valves.
These are the most important guidelines when selecting a solenoid valve. Keep these guidelines in mind before choosing a valve.
Solenoid valves are very sensitive to dirt and only work with clean liquids or air.
Note that indirectly controlled solenoid valves require a permanent pressure differential of around 0.5 bar to function properly. Therefore, you can not use indirect operated valves in a closed circuit or systems with a low inlet pressure. Direct and semi-direct operated valves operate with a pressure differential from 0 bar.
Make sure that the used medium and temperature are compatible with the materials of the valve, such as body and the seal materials.
Solenoid valves open and close fast (between around 10 and 1000 ms). Improper use can cause pressure transients in the system (water hammer).
There are different types of solenoid valves, each with different principles of operation:
Direct operated (operating from 0 bar)
Semi-direct operated (operating from 0 bar)
Indirect operated (pressure differential required, normally at least 0.5 bar)
It is important to choose the right operation principle. Direct operated valves operate from 0 bar. In the valve there is a small orifice which is sealed off by a plunger with a polymer gasket. If the solenoid (electromagnet) is electrically energized, the plunger is lifted by the electromagnetic force and the valve opens. This principle is often used for small valves and is suitable for small flow rates. For larger flow rates, a semi-direct or indirect operated valve is recommended. Both make use of the medium pressure to open and close the valve. Semi-direct operated valves operate from 0 bar and often have a more powerful coil than indirect operated valves. Indirect operated valves need a permanent pressure differential of around 0.5 bar for proper operation. The advantage of indirectly operated valves is that they usually can control large flows with a relatively small coil and thereby have a reduced energy consumption.
Check if there is a permanent pressure differential over the valve of at least 0.5 bar. In this is the case, an indirect operated valve may be chosen (a semi-direct valve is of course also allowed in this case). If this is not the case (low inlet pressure, closed circuit, ..), choose a (semi-)direct operated solenoid valve.
