This solenoid in particular is nice and strong, with a 40mm 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 solenoid has 4xM3 (metric) threaded

holes in the bottom for easy mounting.

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! Works best with a 12V power supply.

Please Note: As of June 7th 2017, we are now selling the 12V version of this

product instead of the 24V!
