Baomain DC 12V Solenoid Electromagnet, 1A Travel 10mm, Keepping Force 5N PushPull, Linear Solenoid BM-0530B

Very nice solenoid here. Very consistent and pretty strong with proper voltage used. I'm using this for a manually activated garage door opener switch... which is triggered by a separate wireless activator. This little guy saved the whole project. Essentially I extended the life of my garage door opener by making my own wireless system, since my original one failed.

Worked fine but unfortunately was not powerful enough for it's intended use. No complaints about the quality. Came with threaded holes and mounting screws...shaft is also threaded with a rubber O ring and cap nut. As others have reported, the screws will bottom out so add small washers and test before tightening.

Used for DIY pinball machine nice solenoid, works as advertised but the return spring is too weak and the solenoid will not return to rest position if there is any kind of mechanical resistance. I hacked my way around this issue by removing the circlip and extending the springs to give them more return force. Some binding of the shaft in the core but when rotated I was able to find a loose enough spot for my application

I bought this 3 years ago for a project. It has never failed to work.

Works as expected.
