Heschen DC Solenoid Electromagnet, Push Pull Type, HS-1564B, DC12V 3A, 20mm Stroke, Initial Force 3N, Max Keep Force 60N, Open Frame, Linear Motion

This is a good solenoid for small projects.Good foot pounds of force for its size and voltage. It moves about 3/4" and retracts when activated. 12 volt power will actuate it easily without issue. The Electromagnetic retracted and spring loaded return solenoid can cycle several times a minute. Doesn't build up much heat. The body doesn't have a lot of mounting options but it can be held down with a bracket.

I have not actually installed this on anything yet. But it bench tested very strong. I am sure it will work fine for my needs.

This is a very small solenoid... it seems well made and I hope it is the right thing for my project. I have not energized it yet.

quality product.

This is a powerful, fast, single action (with spring return) solenoid with a large diameter shaft. This would work well if you don't need the advertised 25 mm stroke. The solenoid I received only has about 16 mm of stroke. Distance to the drilled linkage hole is about 16mm retracted and 32 mm expanded. If those measurements fit your needs, this is an otherwise well built solenoid.

Needed a 25mm/1 inch stroke solenoid. This is advertised as 25mm...but it is 18.8mm. You can remove the end nut and get to 25mm...but without that end nut, the shaft of the solenoid will fall out. So this is not a usable 25mm. Just be aware that if you need a 25mm stroke without the solenoid shaft flying out, this won't work.

I tested the solenoid on 12 volts, and it works well. 30 N is more force than I needed to operate a little sliding trap door, but I needed the 25mm displacement, so, there you are. Works well.

I ordered two of these solenoids to use in tandem on a small shaker table. They work perfectly. I haven't tested them over a long time interval, but so far they are fine. They do not overheat during quick on/off use. The mounting screws were difficult for me to use. A clamp worked fine.
