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.

Hi guys, I’m planning to purchase this solenoid for a project, but would need to mount something to the shaft. I can see that this product has a hole in the shaft which appears to be threaded in the diagram. It doesn’t give the specs of this thread though- would really appreciate it if you could check what size it is. Looks to be M3?

Hi Domantas,

I’ve just tested this solenoid with an M3 screw, and it threaded on just fine :slight_smile:

I’ll update the product page soon!

Hi James,

Thanks, really appreciate you checking!

Keep in mind that solenoids should be used as a short time or momentary operator. If the operation needs to be maintained for a long period than the solenoid should set a mechanical latch. Basically, there needs to be fail safe brought into the equation.

Solenoids are available that use a permanent magnet latch. The magnet holds the plunger in the On position after the power is removed. A reverse power pulse is used to overcome the magnet and a spring returns it to the Off position.

Jeff, I agree with your comment for personal hobby projects. You would never find permanent magnets used in say HV 2000A circuit breakers as such. Horses for courses we would agree.
