Solenoids
Solenoids are electromagnetic devices that convert electrical energy into linear motion. They consist of a coil and a movable core, which shift when the coil is energized, enabling the solenoid to actuate mechanical movements in various applications, such as valves and switches.
How Do Solenoids Work?
An electrical current flows through the coil and it generated a magnetic field. The magnetic field pulls a ferromagnetic plunger in to the center of the coil. The pulnger moves in a linear direction to open a valve or lock a latch. When the power is removes, a spring or gravity returns the plunger to its original position until an electrical current flows through again.Where Solenoids Are Used
- Automotive systems
- Vending and ticket machines
- Electric door locks and security systems
- Industrial autiomation and robotics
- Medical devices
- HVAC systems
- Appliances
