Small push-pull solenoid (ADA412)

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, … read more

I Need A Solenoid To Use As A Central Locking Setup. Does This Solenoid Extend When There Is Voltage Applied & Then Stay Extended When Voltage Is Turned Off? I Then Need It To Retract When Reverse Voltage Is Applied.

Do you have a 24V solenoid?

Hey @Steve100819,

To keep it very basic, a solenoid will only stay activated while the coil is energized. So as soon as you “turn off” the solenoid will return to it’s “off state”. I don’t know of any solenoids that operate the way you want, however, you could modify the design to stay energized until the second signal is received.

In terms of a 24V solenoid this would be my pick. While it is rated up to 36V, it will work fine at 24V or even 12V.

I hope this helps.
