AS 7042 Tubular Push-Pull Solenoid – 24 V / 12 ...
What Is a Micro Push-Pull Solenoid?
A Micro Push-Pull Solenoid is a compact electromagnetic actuator designed to create linear motion through the use of an energized coil. Structurally, it consists of:
-
A copper-wound solenoid coil
-
A central iron armature/plunger
-
A return spring (in many models)
-
A small cylindrical or rectangular housing
When electrical current flows through the solenoid coil, a magnetic field is generated, which pulls the plunger into the coil’s center. Because the plunger has two usable ends, the device can provide either pulling or pushing motion—hence the name push-pull solenoid.
Why “Micro”?
“Micro” indicates that the solenoid is very small—typically designed for applications where space is limited.
For example, the type you described has:
-
Body length around 40 mm
-
A captive plunger (preventing it from falling out)
-
A strong return spring to automatically reset the plunger when power is removed
How It Works (Simple Operation)
-
Apply DC voltage (e.g., 12V):
The coil generates magnetic force, pulling the plunger inward. -
Remove voltage:
The return spring pushes the plunger back to its original position.
This makes the operation straightforward and reliable.
Advantages of Micro Push-Pull Solenoids
-
✔ Very compact—easy to fit in tight spaces
-
✔ Dual-action capability (can push or pull)
-
✔ Captive armature—won’t fall out like some low-cost solenoids
-
✔ Integrated return spring—automatic reset without extra mechanisms
-
✔ Convenient mounting tabs for easy installation

AS 1953 Stronge Force Push Pull Solenoid
Push Pull solenoids consist of a solenoid coil with an armature—a metal plunger—in the middle. When the solenoid coil is energized, the plunger is pulled into the center of the coil. This makes the solenoid able to pull (from one end) or push (from the other)
This push pull solenoid in particular is nice and strong, with a 52 mm long body and a 'captive' armature with a return spring. This means that the solenoid moves when activated with up to 24VDC, and when the voltage is removed, it returns to its original position, which is very useful. Many lower cost solenoids are only push type or only pull type and may not have a captive armature (it'll fall out!) or don't have a return spring. This solenoid has 4xM3 (metric) threaded holes in the side of the housing for easy mounting and assembling.
AS 0837 US Micro linear electromagnetic actuator
Micro linear electromagnetic actuators' definition and principle
Miniature linear solenoid actuators are compact electromechanical devices that make it to convert electrical energy into linear (straight-line) mechanical motion. Unlike larger linear solenoids, they are distinguished by their small size (typically a few millimeters to a few centimeters in length/diameter) and low power consumption, making them ideal for applications where space, weight, and energy efficiency are critical.
- Core Definition
Essentially, a micro linear solenoid actuator is a scaled-down version of a linear solenoid optimized for small-scale linear actuation. It consists of three key components:
Stationary Coil: A thin, insulated copper wire wound on a bobbin (usually made of plastic or ceramic) that generates a magnetic field when electricity is passed through it.
Plunger: A ferromagnetic core (e.g., iron, steel) that slides axially (back and forth) within the magnetic field of the coil.
Return mechanism: A small spring (or in some cases a permanent magnet) that returns the plunger to its original position when the coil is de-energized.
Their primary function is to generate short-stroke linear motion (typically 0.5–10 mm) and moderate forces (typically 1–50 N), depending on design and power input.
- Working Principle
The operation of a micro linear solenoid actuator relies on electromagnetic induction and the interaction between a magnetic field and a ferromagnetic material. This process can be broken down into four key steps:
De-energized state: When no current flows through the coil, the plunger is held in the "rest position" by the return spring (or permanent magnet). At this point, there is no magnetic force acting on the plunger, so it remains stationary.
Power On: When direct current (DC) is applied to the coil, it generates a uniform magnetic field around its axis (according to Ampere's law). This magnetic field magnetizes the ferromagnetic plunger, turning it into a temporary magnet.
Magnetic Attraction and Linear Motion: The magnetized plunger is pulled toward the center of the coil (the area of greatest flux density) to minimize the reluctance (resistance to magnetic flux) of the magnetic circuit. This attractive force forces the plunger to slide axially (linearly) outward or inward (depending on the design) to perform the desired motion (e.g., push a valve, close a switch).
Power-off reset: When the current is cut off, the coil magnetic field disappears. The return spring pushes the plunger back to its initial position, ready for the next cycle.
NOTE: Some designs use a "bipolar" coil (reversing the direction of the current) to achieve bidirectional motion, eliminating the need for a spring.
AS 0643 Pull Type Boxing Solenoid DC 24V
How it works
A pull-type solenoid operates based on the electromagnetic force. It consists of a coil of wire wrapped around a bobbin. When current passes through the copper coil, it generates a magnetic field. This field exerts a force on a ferromagnetic plunger (or armature) within the coil. In a pull-type solenoid, the magnetic field pulls the plunger into the coil, producing linear motion. When the current is turned off, a built in return spring or other mechanical mechanism pushes the plunger back to its original position, deactivating the solenoid.
The structure
Solenoid Coil: A wound component that generates the necessary magnetic field when an electric current is applied. The solenoid coil is typically made of copper wire and is wound helically around a cylinder.
Plunger: The movable part of a solenoid, typically made of a ferromagnetic material such as iron or a magnetic alloy. The plunger is designed to be pulled into the coil when the solenoid is powered on.
Return Spring: This component is used to return the plunger to its original position when the current to the coil is interrupted. The spring is usually located at one end of the plunger and is compressed when the plunger is pulled into the coil.
Frame or Housing: Provides mechanical support and protection for the coil and plunger. The frame can be open or closed, depending on the application requirements.
Application
Locking system: Pull solenoids are commonly used in electric locks. The pulling force of the solenoid can be used to unlock or lock the lock, thus achieving remote or automated access control.
Industrial Automation: They are used in various industrial automation systems to perform tasks such as moving mechanical parts, operating valves, and actuating switches. For example, in a production line, a pull solenoid can be used to move a part to a specific position.
Robotics: Pull solenoids can be used to actuate the joints or limbs of robots, providing the linear motion necessary for precise manipulation and locomotion.
Vending machines: In vending machines, pull solenoids can be used to dispense merchandise. For example, when a user purchases an item, the solenoid pulls a mechanism that releases the selected item.
Pinball Machines: They are used to pull the firing lever in pinball machines, providing the force needed to launch the ball.

AS 1040 Micro Push Pull Solenoid
What is Micro Push Pull Solenoid ?
Micro Push Pull Solenoid is basically electromagnet: it is made of a solenoid coil of copper wire with an armature (a slug of metal) iron/plunger in the middle. When the solenoid coil is energized, the plunger is pulled into the center by the solenoid coil of magnet force. This makes the micro push pull solenoid able to pull (from one end) or push (from the other).
This mirco push pull solenoid in particular is very small, with a 40mm long body and a 'captive' armature with a return strong spring. This means that when activated with ~12V DC, the solenoid moves and then the voltage is removed it springs back to the original position, which is quite simply operation. Many lower cost solenoids are only push type or only pull type and may not have a captive armature (it'll fall out!) or don't have a return spring. This one even has nice mounting tabs, its a great all-purpose solenoid.
AS 0730 high force push pull solenoid 12V
AS 0730 high force push pull solenoid 12v
Essentially, a solenoid is an electromagnet: it's made of a copper coil wound on a frame housing, with a free-flowing metal frame type housing in the center of the coil. When electricity is powered on, the plunger is pulled toward the center of the solenoid coil. This allows the solenoid to pull ("pull" from one end) or push ("push" from the other end).
This push pull solenoid is quite nice and has a lot more power for a reasonable size (compared to our small solenoid). It has a 40mm long housing and a fixed frame with a spring (to hold the shaft). This means that the solenoid moves the shaft when 24V is applied, and when there is no pulling force, the return spring returns the shaft to its original position. It is very practical. Many cheap solenoids can only push or pull the shaft and have no armature to hold the shaft (the shaft will fall off the solenoid). Cheap solenoids also have no return spring.

The solenoid actuator push pull is mainly composed of open frame housing with permeability, a big coil of copper wirl, bobbin, plunger and iron core. When the solenoid coil is energized, the slug is pulled into the center of the coil. This makes the solenoid able to pull (from one end) or push (from the other)Because of its simple structure and low cost, it is widely used in life automation equipment, such as small household appliances, game and vending machines.

What is DC Linear Solenoid ?
DC linear solenoid ( it is also call linear actuator ) features robust linear movement and are well suited for "heavy duty" applications. This kind of DC linear solenoid design allows high holding force at a comparably low current. Therefore push pull solenoids are ideal actuators for applications for which power consumption and heat dissipation are critical. It is named "Push/Pull" because both shaft ends are available, so the linear solenoid can be used as pushing solenoid or pulling solenoid, depending which shaft end is used for mechanical connection - but because of reluctance working principle the active moving direction when powering the coil is only unidirectional.

How Does a Push Pull Solenoid Actuator Work ?
AS 0635 Push Pull Solenoid actuator powered unit is Push-Pull open frame type, with linear motion and plunger spring return design, open solenoid coil form, DC electron magnet. It has been used widely in home appliances, vending machines, a game machine.....
Efficient and durable push-pull solenoids generate a significant amount of force for their comparatively small size, this makes the push pull particularly suited to high-force short-stroke applications.
The compact size of the solenoid optimises the magnetic flux path, alongside a precision coil winding technique which packs the maximum amount of copper wire into the available space, allowing maximum force to be generated.
Push-pull solenoids have 2 shafts relative to the mounting studs, the shaft on the same side as the studs pushes and the shaft on the armature side pulls, so you have both options on the same solenoid. As opposed to other solenoids like tubulars which are independent of each other.
It is steady, durable and energy-saving, and had a long lifespan with more than 300,000 cycle time. In the anti-theft and shockproof design, the lock is better than other kinds of locks. After connecting the wires and when the current is available, the electric lock can control the door’s opening and closing.
Note: Take care of polarity while making the connection without a connector (i.e. Red wire should be connected to the positive and Black wire to the negative.)

AS 1564 DC12V Solenoid Push and Pull: The Ultim...
About AS 1564 Solenoid Push and Pull :
This compact solenoid operates as a miniature electromagnet. It consists of a tightly wound copper coil surrounding a central metal plunger (armature). When energized with 12VDC or 24V DC, the electromagnetic field pulls the plunger into the center of the coil, creating linear motion. Depending on the application, this motion can be used for either pushing or pulling actions.
This particular model features a 64 mm-long body and includes a captive armature with a built-in return spring. When power is applied, the plunger is pulled inward; once the power is removed, the spring reliably returns it to its original position. Unlike many low-cost solenoids—which may be limited to push or pull types and lack either a return spring or captive plunger—this design offers improved reliability and ease of use. Additionally, integrated mounting tabs allow for easy installation.
Key Features:
Compact size: 64mm body length
Captive armature with return spring for automatic reset
Supports both push and pull operation
Operates at up to 12V or 24V DC, drawing approximately 250mA to 2 A
Sturdy mounting tabs for secure installation
Important Notes for Use:
To control this solenoid with a microcontroller (such as an Arduino), a power transistor is required to handle the current draw. A flyback diode must also be used to protect your circuit from voltage spikes generated when the solenoid is de-energized. Ensure you use a reliable power source, as solenoids demand significant current during activation and are not suitable for use with weak power sources like standard 9V batteries.
