This is a solenoid’s driving part. When a magnetic field is emitted, it is drawn toward the fixed iron core.
Made up mainly of a magnetic substance, this is manufactured with holes (taps) on most solenoids.
This is the main part of the solenoid that emits a magnetic field when electric current flows through it. Together, the bobbin, wire, lead and exterior tape are called the coil. Some coils have temperature fuses or diodes on the inside.
When a magnetic field is emitted from the coil, it attracts the moveable iron core along the magnetic flux. The shape of the moveable and fixed iron cores and the attraction characteristics are intimately related.
WHAT IS A SOLENOID?
Solenoids are an electrical device that move a plunger in a straight line by running an electric current through a coil and using the resultant magnetic force. This straight line movement allows us to reach speeds unachievable with a motor, making solenoids suitable for a wide range of uses and limited only by your imagination.
Solenoid currents are broadly divided into direct current (DC) and alternating current (AC). Our firm primarily manufacturers DC solenoids.
What is a DC solenoid?
It is an electric part that emits an electromagnetic field through a copper wire to pull in a magnetic, movable iron core.
When current flows through the wire, the iron core is attracted toward the fixed iron core inside the wire, constantly drawn to the space within the electric current. When the electric current is cut off, the attraction ceases. (Depending on the model, there may be some residual magnetism.)
There are many varieties, such as regular pull solenoids that work this way, push solenoids equipped with push bars that use attraction to apply pressure and self-maintaining solenoids that use embedded permanent magnets to maintain various states.
Features of DC solenoids
By Changing the shape of the iron core, it is possible to change the distance and power of the attraction.
Even if the plunger stops partway, the voltage will not change, making them safe.
There is no incoming current, so setting up the power supply is easy.
Unlike AC, the design is low-noise, emitting no buzzing noises.
Compared to a motor, solenoid excels in low power and price.
3 major Types of Solenoids
DC Solenoids have several features such as below.
The core operation of a solenoid is straight line movement. If you need movement in a straight, direct line, solenoids prove to be faster than motors, and controlling them is simple.Changing the coil piece also allows for greater Force. *Force is the force that pulls the solenoid plunger back.
A Solenoid is electronic part that moves an iron core with the magnetic flux produced when current is run through the coil. While current is being applied to the coil, the movable plunger is sucked into the coil.Learn more
By equipping a push bar to a Plunger, a Push Solenoid extends a push bar instead of retracting.Learn more
Magnetic Latching Solenoid
Magnetic Latching Solenoids have a built in permanent magnet that hold the plunger in external position even when no power is applied.Learn more
