Does some electronic component/solenoid variation like this exist?

>Forcefully pull metal core inwards if energized one way
>Forcefully push metal core outwards if energized another

I realize I can use a servo motor, but a solenoid like device would be faster and more compact.
>>
i've seen this kind of thing inside computers as an anti-tamper device. they prevent anyone from opening the computer case unless the solenoid is retracted.

linear actuator

Two of those, mounted back to back.

Push-pull solenoid. Basically two coils with the core in the middle.

I always wondered what these were based off of.
>>
>>921929
What are they?

>>921220
How does your pic related not fit the bill?
>>
>>921220
I don't understand. You de-energize it to have the spring push the core out. Energize it to have the core pushed in.
Do you want the core to remain in an undetermined state when deenergized?
Linear actuator would be your best bet, or look for double action solenoids if those fit.
>>
>>921220
Don't all solenoids do what you specify?

well, you could just get a normal linear-stroke solenoid and bend a spring to hold it halfway extended when it isn't powered....

reverse stroke solenoids i believe

You could replace the metal shaft with a neodym magnet.
You need a bipolar driver, obv.
>>
You could always pull one from the door of any car with electronic locks. They might be a bit big though.
>>
>>923815you could also use the starting solenoid but I think those are one way.
>>
Solenoids are a pain to work with. They seem simple but they can really cause issues with a microcontroller. Power door lock units are cheap, very reliable, and perform exactly like you describe.
