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.
AS 0626 DC Solenoid Actuator Push Pull
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.

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).

Part 1: Long Stroke Solenoid Working Principle
The long-stroke solenoid is mainly composed of a coil, a moving iron core, a static iron core, a power controller, etc. Its working principle is as follows
1.1 Generate suction based on electromagnetic induction: When the coil is energized, the current passes through the coil wound on the iron core. According to Ampere's law and Faraday's law of electromagnetic induction, a strong magnetic field will be generated inside and around the coil.
1.2 The moving iron core and the static iron core are attracted: Under the action of the magnetic field, the iron core is magnetized, and the moving iron core and the static iron core become two magnets with opposite polarities, generating electromagnetic suction. When the electromagnetic suction force is greater than the reaction force or other resistance of the spring, the moving iron core begins to move toward the static iron core.
1.3 To achieve linear reciprocating motion: The long-stroke solenoid uses the leakage flux principle of the spiral tube to enable the moving iron core and the static iron core to be attracted over a long distance, driving the traction rod or push rod and other components to achieve linear reciprocating motion, thereby pushing or pulling the external load.
1.4 Control method and energy-saving principle: The power supply plus electric control conversion method is adopted, and the high-power start-up is used to enable the solenoid to quickly generate sufficient suction force. After the moving iron core is attracted, it is switched to low power to maintain, which not only ensures the normal operation of the solenoid, but also reduces energy consumption and improves work efficiency.
Part 2 : The main characteristics of the long-stroke solenoid are as follows:
2.1: Long stroke: This is a significant feature. Compared with ordinary DC solenoids, it can provide a longer working stroke and can meet the operation scenarios with higher distance requirements. For example, in some automated production equipment, it is very suitable when objects need to be pushed or pulled for a long distance.
2.2: Strong force: It has sufficient thrust and pulling force, and can drive heavier objects to move linearly, so it can be widely used in the drive system of mechanical devices.
2.3: Fast response speed: It can start in a short time, make the iron core move, quickly convert electrical energy into mechanical energy, and effectively improve the working efficiency of the equipment.
2.4: Adjustability: The thrust, pull and travel speed can be adjusted by changing the current, number of coil turns and other parameters to adapt to different working requirements.
2.5: Simple and compact structure: The overall structural design is relatively reasonable, occupies a small space, and is easy to install inside various equipment and instruments, which is conducive to the miniaturization design of the equipment.
Part 3 : The differences between long-stroke solenoids and comment solenoids :
3.1: Stroke
Long-stroke push-pull solenoids have a longer working stroke and can push or pull objects over a long distance. They are usually used in occasions with high distance requirements.
3.2 Ordinary solenoids have a shorter stroke and are mainly used to produce adsorption within a smaller distance range.
3.3 Functional use
Long-stroke push-pull solenoids focus on realizing the linear push-pull action of objects, such as being used to push materials in automation equipment.
Ordinary solenoids are mainly used to adsorb ferromagnetic materials, such as common solenoidic cranes that use solenoids to absorb steel, or for adsorption and locking of door locks.
3.4: Strength characteristics
The thrust and pull of long-stroke push-pull solenoids are relatively more concerned. They are designed to effectively drive objects in a longer stroke.
Ordinary solenoids mainly consider the adsorption force, and the magnitude of the adsorption force depends on factors such as the magnetic field strength.
Part 4 : The working efficiency of long-stroke solenoids is affected by the following factors:
4.1 : Power supply factors
Voltage stability: Stable and appropriate voltage can ensure the normal operation of the solenoid. Excessive voltage fluctuations can easily make the working state unstable and affect efficiency.
4.2 Current size: The current size is directly related to the strength of the magnetic field generated by the solenoid, which in turn affects its thrust, pull and movement speed. The appropriate current helps to improve efficiency.
4.3 : Coil related
Coil turns: Different turns will change the magnetic field strength. A reasonable number of turns can optimize the performance of the solenoid and make it more efficient in long-stroke work. Coil material: High-quality conductive materials can reduce resistance, reduce power loss, and help improve work efficiency.
4.4: Core situation
Core material: Selecting a core material with good magnetic conductivity can enhance the magnetic field and improve the working effect of the solenoid.
Core shape and size: The appropriate shape and size help to evenly distribute the magnetic field and improve efficiency.
4.5: Working environment
- Temperature: Too high or too low temperature may affect the coil resistance, core magnetic conductivity, etc., and thus change the efficiency.
- Humidity: High humidity may cause problems such as short circuits, affect the normal operation of the solenoid, and reduce efficiency.
4.6 : Load conditions
- Load weight: Too heavy a load will slow down the solenoid's movement, increase energy consumption, and reduce work efficiency; only a suitable load can ensure efficient operation.
- Load movement resistance: If the movement resistance is large, the solenoid needs to consume more energy to overcome it, which will also affect efficiency.
AS 15063 Lifting Permanent Magnet / Small Round...
What is a Lifting Permanent Magnet ?
A lifting Permanent Magnet is composed of two sets of permanent magnets: one set of magnets with fixed polarities, and one set of magnets with reversible polarities. A DC current pulse in different directions through the inside solenoid coil around the latter reverses its polarities and makes in two statuses: with or without external holding force. The device needs the DC current pulse for less than one second in order to be activated and deactivated. During the whole period of lifting a load the device doesn’t need any electricity any more.

What is a keep solenoid ?
Keep Solenoids are fixed with permanent magnet embedded on the magnetic circuit. Plunger is pulled by instantaneous current and the pull continues after the current is shut off. Plunger is released by instantaneous reverse current. Good for power saving.
How does a keep solenoid work ?
A keep solenoid is a power-saving DC powered solenoid combining the magnetic circuit of an ordinary DC solenoid with permanent magnets inside. The plunger is pulled by an instantaneous application of reverse voltage, held there even if the voltage is turned off, and released by an instantaneous application of reverse voltage.
The type of Pull, Hold and Release Mechanism Structure
-
PullType Keep Solenoid
At application of voltage, the plunger is pulled in by the combined magnetomotive force of the built-in permanent magnet and the solenoid coil.
B. HoldType Keep Solenoid
Hold type Solenoid is the plunger is held by the magnetomotive force of the built-in permanent magnet only. The hold type position can be fix in the one side or both side depend on real application.
C. Release type of keep solenoid
The plunger is released by the reverse magnetomotive force of the solenoid coil canceling the magnetomotive force of the built-in permanent magnet.
Solenoid Coil Types of Keep Solenoid
The keep solenoid is built in either in a single coil type or double coil type.
. Single Solenoid coil type
- This type of solenoid performs pull and re- lease with only one coil, so that the polarity of the coil must be reversed at switching between pull and release. When the pull force is given priority and the power exceeds the rated power, the releasing voltage must be lowered. Or if the rated voltage + 10% is used, a resistance must be placed in series in the release circuit (This resistance will be specified in the test report on the pilot sample (s). )
- Double coil type
- This type of solenoid, having a pull coil and release coil, is simple in circuit design.
- For the double coil type, please specify" Plus common" or " minus common" for its configuration.
Compared with the single coil type of the same capacity, the pull force of this type is a little smaller because of the smaller pull coil space designed to provide space for the release coil.

What is a small push-pull solenoid
Push-Pull Solenoid is a subset of electromechanical devices and a fundamental component in various applications across all of the industries. From smart door locks and printers to vending machines and car automation systems, these push-pull solenoids contribute significantly to the seamless operation of these devices.
How the small Push-Pull Solenoid work ?
A push-pull solenoid operates based on the concept of electromagnetic attraction and repulsion. When an electrical current goes through the coil of the solenoid, it generates a magnetic field. This magnetic field subsequently induces a mechanical force on a movable plunger, causing it to move in linear direction of the magnetic field, thereby ‘pushing’ or ‘pulling’ as required.
Push movement action: The solenoid ‘pushes’ when the plunger is extended out of the solenoid body under the influence of the magnetic field.
Pull movement action: Conversely, the solenoid ‘pulls’ when the plunger is drawn into the solenoid body due to the magnetic field.
Construction and Working Principle
Push-pull solenoids consist of three primary components – a coil, a plunger, and a return spring. The coil, typically made of solenoid copper wire, is wound around a plastic bobbin, forming the body of the solenoid. The plunger, usually composed of ferromagnetic material, is positioned within the coil, ready to move under the influence of the magnetic field. The return spring, on the other hand, is responsible for returning the plunger to its original position once the electric current is turned off.
When an electric current flows through the solenoid coil, it creates a magnetic field. This magnetic field induces a force on the plunger, causing it to move. If the magnetic field is aligned such that it pulls the plunger into the coil, it is termed as the ‘pull’ action. Conversely, if the magnetic field pushes the plunger out of the coil, it’s the ‘push’ action. The return spring, located at the opposite end of the plunger, pushes the plunger back to its original position when the current is turned off, thus resetting the solenoid for the next operation.

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. Applications can be found in medical, laboratory and analytical equipment.

AS 20030 DC Suction Electromagnet
What is an Electromagnetic lifter ?
An electromagnet lifter is a device that works on the principle of electromagnet and consists of an iron core, a copper coil and a round metal disk. When current passes through the copper coil, the magnetic field generated will make the iron core a temporary magnet, which in turn attracts nearby metal objects. The function of the round disk is to enhance the suction force, because the magnetic field on the round disk and the magnetic field generated by the iron core will be superimposed to form a stronger magnetic force. This device has a stronger adsorption force than ordinary magnets and is widely used in industries, family life and scientific research.
These kind of electromagnet lifter are portable, cost-effective, and efficient solutions to easily lift items such as steel plates, metallic plates, sheets, coils, tubes, disks, etc. It is usually consists of rare earth metals and alloys (e.g. ferrite) that make it capable of producing a stronger magnetic field. Its magnetic field is not consistent as it can switched on or off based on the particular needs.
Working principle:
The working principle of the electromagnet lifter is based on the interaction between the magnetic field generated by electromagnetic induction and the metal object. When current passes through the copper coil, a magnetic field is generated, which is transmitted to the disk through the iron core to form a magnetic field environment. If a metal object nearby enters this magnetic field environment, the metal object will be adsorbed to the disk under the action of magnetic force. The size of the adsorption force depends on the strength of the current and the size of the magnetic field, which is why the suction cup electromagnet can adjust the adsorption force as needed.
