What Is a Solenoid Coil?
Energy for linear motion is provided by the electromagnetic field when an electrical current is passed through the coil. These solenoid coils are regarded as one of the simplest forms of linear actuation devices.
How Solenoid Coils Function
The key components of a solenoid coil are the magnetic field and electricity. Magnets cannot be turned off once magnetized and continually emit their magnetic field, but this problem is not a factor when operating a solenoid coil. The magnetic field of a solenoid coil is activated by electricity, so it is possible to control when and how the magnetic field is used. The wires of a solenoid coil are wound into a coil where each curried wire produces the same magnetic field as a single straight wire. This is done to create a stronger magnetic field because all wires produce a weak magnetic field when electricity passes through them.
A closed loop is required in every electronic device between the thing being powered and the power source. Using a switch is a safe and convenient way to break the connection between the powered device and the power source. With an increase in power, the size of the switch required to break the connection is also increased. It takes a small amount of energy to turn the switch on and off, although the amount of power increases with the size of the switch.
A solenoid can provide necessary energy since its operation does not require much energy. Typically, a 24-volt solenoid can turn on a 240-volt machine. The back and forth motion of a solenoid allows an application to activate or turn off. The solenoid makes the activation of large pieces of equipment easy without the need for excessive energy. A proportional solenoid coil converts an electric signal into a proportional mechanical force, allowing for a variance in the position and force relative to the current level.
Types of Solenoid Coils
All solenoid coils use the same electrical principles in their operation, although they differ in design, usage, and materials. They are further divided between alternating current and direct current, in addition to categorization by being wrapped and encapsulated.
AC Laminated Solenoid Coil
The AC solenoid can deliver a large amount of force in the first stroke due to the high input of current when the solenoid coil is turned on. The coil can deliver more strokes because of this particular feature. The AC laminated solenoid coil produces a buzzing sound. They also come in different configurations. These are ideal for applications that require immediate action, such as medical equipment, vehicles, and printers.
DC C-Frame Solenoid Coil
To provide linear motion, the C-frame of a DC C-frame solenoid coil has an open frame. This type of solenoid coil is the simplest solenoid and has a cost-effective design but provides exceptionally high performance. It is found in a pull or push configuration and is used for simple applications such as circuit breakers, coin counters, scanners, and point of sale devices.
Linear Solenoid Coil
This type of coil is also referred to as a linear electromechanical actuator. It can be continuously energized or used as an on or off switch. The type of coil can be designed as a proportional solenoid coil that changes the position of the plunger in relation to the power input. The name linear solenoid coil relates to the linear movement of the plunger when the coil is activated.
DC – D Frame Solenoid Coil
This type of coil is enclosed in two D-frames on both sides. This frame allows for a slightly higher out force and a greater resistance to environmental factors. D frame solenoid coils have a design that is economical for high volume uses and continuous duty, and they are available for on and off applications.
Applications and Uses of Solenoid Coils
Solenoid coils are used in automatic locking mechanisms, including door locks used in higher security areas. They are also used in medical devices that include oxygen delivery systems and gas chromatography. In the automotive sector, they are also essential in the production of automobiles as they are also found in air conditioning control systems. Other applications include aviation, irrigation systems, pinball machines, and pneumatic systems.
Choosing the Right Solenoid Coil Supplier
For the most beneficial outcome when purchasing solenoid coils from a solenoid coil supplier, it is important to compare several suppliers using our directory of solenoid coil companies. Each solenoid coil company has a business profile page that highlights their areas of experience and capabilities, along with a contact form to directly communicate with them for more information or request a quote. Review each solenoid coil business website using our patented website previewer for a better idea of what each business specializes in. Then, use our simple RFQ form to contact multiple solenoid coil companies with the same form.
