AS 2214 DC 24V Electromagnetic brake Clutch holding for Forklift Stacker Small Electric Wheelchair
Unit Dimension: φ22*14mm / 0.87 * 0.55 Inch
Working Principle :
When the copper coil of the brake is energized, the copper coil generates a magnetic field, the armature is attracted to the yoke by magnetic force, and the armature is disengaged from the brake disc. At this time, the brake disc is normally rotated by the motor shaft; when the coil is de-energized, the magnetic field disappears and the armature disappears. Pushed by the force of the spring toward the brake disc, it generates friction torque and brakes.

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 1003231 DC 12 or 24V Rectangular Holding El...
Why Choose a Rectangular Holding Electromagnet?
A rectangular holding electromagnet is an excellent choice because its extended poles provide a larger and more uniform contact area, making it ideal for lifting flat and large ferromagnetic surfaces such as steel plates, beams, or bars. The increased contact area also allows for greater magnetic field reach, enhancing performance with rough or irregularly shaped workpieces and working effectively even through small air gaps. This minimizes the risk of load loss and improves overall operational safety.
Key features include:
-
Coil protection: Resin-coated, with protection class IP65 or IP54
-
Durable housing: Galvanized magnet body and outer surface for corrosion resistance
-
Easy installation: Anchoring via threaded holes for secure mounting
These characteristics make them especially suitable for industrial lifting, handling, and holding applications where both safety and reliability are critical.
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.

What Are Electromagnets?
Electromagnets (also called solenoids) generate magnetic force when an electric current passes through built in solenoid coil. They contain a ferromagnetic core, whose magnetic domains align with the solenoid coil;s magnetic field, enhancing magnetism as current increases.
There are two types of electromagnets
A: Power-on-to-hold electromagnets: Retain their magnetic field only when current is applied.
B : Permanent electromagnets: Maintain their magnetic field even when power is off, suitable for long-term applications.
How Strong Are Electromagnets?
Their strength is directly tied to the electric current flowing through them: a higher current aligns more domains in the core, increasing magnetic force (up to a maximum limit).

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.

Working Principle of Smart Door Lock
The smart door lock consists of two parts: the solenoid valve and the lock body. The solenoid valve generates a strong electromagnetic force when the current passing through the solenoid coil, pushing the iron core ( plunger ) to move linearly, and pushing the lock tongue to the door frame to achieve the extension and retraction control of the smart lock . When the power is off, the magnetic force on the solenoid valve disappears, and the lock tongue will return to its original working position by the force of spring.
Due to different designs, electromagnetic door locks are also divided into two types, normally open and normally closed style.
The normally open electromagnetic lock, also known as the power-off unlocking electromagnetic lock, opens when the solenoid valve is powered on. When the solenoid valve is out of power, the lock body is closed.
The normally closed electromagnetic lock, also known as the power-off locking electromagnetic lock, closes when the solenoid valve is powered on. When the solenoid valve is out of power, the lock body is opened.
Both types can be implemented in practical applications and can be set according to actual needs.
- Working voltage: it usually works on DC12V or 24V DC, low power consumption design (current about 200-500mA).
- Action time: extremely fast response speed (<50ms), suitable for instant unlocking needs.
Design
The three-level conversion of electrical energy → magnetic energy → mechanical energy depends on the coordinated optimization of coil turns, current intensity and core material (such as soft magnetic alloy).
