Small Push-Pull Solenoid - 12VDC
PRODUCT ID: 412
Solenoids are basically electromagnets: they are made of a big coil of copper
wire with an armature (a slug of metal) in the middle. When the 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)
This solenoid in particular is fairly small, with a 30mm long body and a 'captive'
armature with a return spring. This means that when activated with up to
12VDC, the solenoid moves and then the voltage is removed it springs back to
the original position, which is quite handy. 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.
To drive a solenoid you will need a power transistor and a diode, check this
diagram for how to wire it to an Arduino or other microcontroller.
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 250mA, so don't try to
power it with a 9V battery!
