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.
