5V Solenoid Linear Actuator DC Motor Miniature Electromagnet

Out of stock

Solenoids are basically electromagnets: they are made of a coil of copper wire with an armature (a slug of metal) in the middle. This is a special kind of solenoid. It has two wires to power it. It pulls the armature inside when not powered. When powered in one direction, it pulls the armature inside with greater force. When powered in the opposite direction, the magnetic force is weakened and the armature can be pulled out easily with less force.

To drive a solenoid from an Arduino or any other microcontroller, you will need a power transistor and a diode. You can also use our relay boards to control the solenoid from an Arduino. You will need a fairly good power supply to drive a solenoid, as a lot of current will rush into the solenoid to charge up the electro-magnet, about 100mA, so don't try to power it with a 9V battery!


  • 5V DC operation (you can use 5-6DC volts)
  • Pull type
  • Miniature Size
  • Widely used in automation equipment, such as Game Machines,Slot Machines,The Ticket Vending Machines, Cash Register, Automatic Office Equipment etc.
