Heschen DC12V 3A DC Solenoid Electromagnet, Max Force 60N, 20mm Stroke

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.

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.

Like all solenoids, these produce a remarkably weak push when the rod is fully extended and the manufacturer doesn't state what that force is. The advertised force is the force produced only when the rod is all the way in. I need the force to be strong to get the load moving, so these don't work for me. Also, I bought two of them and the stroke was a couple of mm short of the advertised stroke on both of them. I assumed that might be the case when I ordered them, though, so that shortcoming was not a problem for me.

Zum Testen habe ich den Magneten an einer Kranwaage ziehen lassen. Mit einem Spannschloss habe ich je Versuch unterschiedliche Endpositionen festgelegt. Meiner Meinung nach kann der Magnet bei 3A in der Anfangsposition ca. 500 g ziehen (5 Newton), und in der Endposition max. 3,1 kg (30,x N) halten. Damit konnte zumindest ich nicht die angegebenen initialen 12 N bestätigen. Was die maximale Haltekraft angeht, so kann man die laut Herstellerangabe nur erreichen, wenn man eine Unterlegscheibe ausbaut, was ich aber nicht getan habe. Der angegebene Hub von 20mm ist nach meiner Messung korrekt. Im Endeffekt habe ich also den Eindruck, dass der Magnet ein wenig schwächer sein könnte, als angegeben. Möglicherweise hätte ich aber auch mit einer besseren Verkabelung, und wie gesagt durch Entfernen des Dämpfers noch ein bisschen mehr rausholen können. Auf jeden Fall finde ich die Kraft dennoch beeindruckend, daher gebe ich doch die vollen Punkte.

Bonne qualité

届いたものは外箱とビニールに包まれた本体の以上で仕様書などはありません。 本体には一応動作DCとA・型式・メーカー名・生産国がシールで貼り付けてあるがシールの裏に取付用のネジ穴があり塞がれていました。 動作電初はシールに12Vと記載がありましたが5～6Vくらいで動作開始します。
