How Does Tubular Solenoid Push Pull Work?

Tubular Solenoid Push Pull works on the principle of electromagnetism. The electrical current flowing through the coil produces a magnetic field around the iron core. This magnetic field generates the movement of the internal plunger, thus providing the linear mechanical motion.

The main stages of the working process include:

Electrical input

DC voltage is applied to the copper coil.

Generation of the magnetic field

It creates the electromagnetic force in the energized coil.

Plunger travel

The magnetic field moves the plunger in the tube-shaped housing.

Mechanical output

The plunger transforms this motion into pushing or pulling force.

Movement back

When the power is turned off, the spring or another external device returns the plunger to its initial position.

The force output depends on the number of the coil turns, current, magnetic material, air gap, stroke length, and mechanical design.

Main Features of Tubular Solenoid Push Pull:

The tubular solenoid push-pull is the cylindrical solenoid with high magnetic efficiency and reliable linear motion. Its main features are high force density, precise stroke control, easy installation, and a long-life period.

Common FAQs of Tubular Solenoid Push Pull

1. What is a push-pull tubular solenoid?

A tubular solenoid push-pull is an electromagnetic linear actuator that transforms electrical energy into mechanical motion. Using a DC energy supply to the coil provides a magnetic field causing movement of the internal plunger forward or backward and producing push and pull force. The cylindrical design of the device allows for efficient magnetic performance, a compact installation size, and reliable operation. The product is widely used in industrial automation, valve control, robotics, medical devices, security devices, and customized machinery, which requires precise linear motion.

2. What is the difference between Tubular solenoid Push Pull and Frame Solenoid ?

The main difference is in the mechanical and magnetic designs. A tubular solenoid push-pull uses a cylindrical housing with a plunger in the middle, providing such advantages as increased magnetic efficiency, smooth operation, and compact installation. A frame solenoid uses an open-frame design with stamped metal components, which might be suitable for some low-cost or particular mounting method applications.

In general, tubular solenoids are preferred for applications requiring high force density, good alignment, long lifetime, and strong mechanical protection.

3. How to choose the right Tubular Solenoid Push Pull for your application?

Things to Consider While Choosing a Tubular Solenoid Push Pull:

Required push and pull force

Stroke Distance

Operating voltage (DC 5V, 12V, 24V, 48V etc.)

Duty cycle requirements

Operating frequency

Installation space . . .

Operating temperature

Environmental factors and

We advise you to inform the manufacturer about your load requirements, working conditions, drawings and application details in order to optimize the solenoid.

4. Can Tubular Solenoid Push Pull work all the time?

Yes, but it depends on duty cycle design. Some tubular solenoids are designed for intermittent duty, while other ones can be 100% duty cycle with good coil design and heat management.

For continuous operation, the following should be considered:

Increased coil temperature

Voltage stability

Heat extraction

Ambient temperature.

Required lifetime

Inappropriate duty cycle selection might cause overheating and decrease product lifetime.

5. What are the elements that affect the force output of a Tubular Solenoid Push Pull?

There are several technical aspects affecting the force output:

Coil winding turns

Voltage and current supply

Magnetic material quality

Plunger design

Air gap distance

Stroke length

Spring back.

Mechanical load

But generally, shorter strokes produce more force. Long strokes leave less electromagnetic force available. Professionals optimize magnetic circuit to achieve the necessary performance.

6. Can the Tubular Solenoid Push Pull be customized?

Yes. We also customize our Tubular Solenoid Push Pull products according to customer requirements. Customization options usually include:

Voltage selector

Push / pull force adjustment

Stroke length

Plunger design

Shaft design

Mounting frame

Connector & cable selection

Spring’s configuration

Special coating or waterproof requirements.

For OEM projects, the manufacturer can offer engineering support, prototype samples, testing and mass production services.

7. Why does my Tubular Solenoid Push Pull have little force or does not move?

Common reasons are

Low-Force Issues:

Insufficient supply current

Voltage out of range

Overloading the machine

Too long a stroke

spring force error

No Movement Issues:

Damaged coils

Loose electrical connection.

Mechanical obstruction

Incorrect Installation Position

Begin with checking the power supply, coil resistance, mechanical operation, and specifications.

8. What is the working lifetime of a Tubular Solenoid Push Pull?

Service lifetime depends on operating conditions, design quality and application requirements. Under appropriate working conditions, a good tubular solenoid can normally last for 100,000 or more cycles.

Longevity factors include:

Operation Frequency

Loading case

Duty cycle

temp

Wear and tear

Material quality

Precision manufacturing

Choose a manufacturer with professional testing capabilities and quality control system, to ensure long-term stable performance for demanding industrial applications.

How to Choose the Tubular Solenoid Push Pull?

There are several technical factors to be considered in order to choose the right tubular solenoid push-pull.

1. Determine the force required

The first step is to determine the required push force and pull force. Different applications require different force values. The wrong selection of the solenoid that is too weak can lead to failure, while the excess of power will increase costs and power consumption.

2. Stroke length determination

Stroke is the distance the plunger has to move. The common stroke requirements are 5 mm, 10 mm, 20 mm, or custom length. The longer strokes usually are less powerful.

3. Choose operating voltage

The common voltage values are DC 5V, 12V, 24V, and 48V. For staboperation, the power supply must matchith the coil parameters.

4. Verify the duty cycle

The duty cycle determines the duration of the solenoid operation. If you want to operate the solenoid continuously, then you need to choose the 100% duty cycle design. The intermittent duty cycle models can be used for short activation periods.

5. Consider installation space

Before the solenoid selection, it is necessary to measure the available space for the installation. The tubular solenoids have very good space efficiency but still require proper mechanical integration.

6. Consider working environment

It is necessary to consider the temperature, humidity, vibration, dust, and corrosion conditions. In harsh environmental conditions, special materials and coatings may be required.

7. Discuss your custom requirements

For OEM projects there can be special shafts, connectors, springs, mounting brackets or special force curves needed. The professional manufacturer can help you to optimize the design.

The correct choice will increase reliability and decrease energy usage, ensuring the product performs well over a long period.

How to avoid the comment “Error in Tubular Solenoid Push-Pull Design”

Many designers assume the constant force value along the entire stroke. But with the increasing of the air gap, the electromagnetic force decreases.

Selecting the wrong voltage and current

Insufficient current leads to insufficient force. Excess of current can cause overheating.

No duty cycle consideration

Solenoids are intermittent devices. The continuous operation can shorten their life.

Heat management ignoring

Good design is required to control the temperature of the coil.

Wrong mechanical load calculation

The force of the solenoid has to be enough for the friction, spring force, and safety margin.

Ignoring the alignment during installation

Misalignment causes the friction and lowers performance.

Omitting the prototype testing

Before the mass production, the real application testing is necessary.
