Heschen DC Solenoid Electromagnet, Push Pull Type, HS-0530B, DC12V 1.7A, 10mm Stroke, Initial Force 0.5N, Max Keep Force 5N, Open Frame, Linear Motion

Handy little piece of kit, I used it to repair a Rolls Royce boot lock.

bought it to work a lock

It is difficult to imagine a more simple device. Ideal as a teaching aid. The threaded base makes it very easy to install in exactly the right position. It makes a fairly loud 'CLICK' in operation but it is simple to dismantle and it would be easy to install a rubber buffer or two.

Thought this might be a good actuator for a non-return valve I designed to a 100mm duct. Ok- good in terms of actuation by gets far TOO HOT after even a couple of minutes on a 12v supply- so much so you WILL burn your fingers (I know by experience). The (thin) cables also heat up away from the unit. Too much of a fire risk once installed, so unfortunately going to e-waste...

The solenoid works reliably, it is just much weaker than expected and overheats easily. It certainly isn't outputting 5N.

Although rated at (maximum) 12 volts, the solenoid also worked well with a 9 volt PP9 battery, but didn't last very long due to the current draw by the solenoid. However, I found that it worked really well using 8 AA 1.2v rechargeable batteries as they provide sufficient current for a longer period of time. If you are using this device with an Arduino microcontroller (as I did), it is recommended that you use a separate power supply as the current draw could damage the Arduino.

These solenoids really jump, provided you operate them at the rated 12v. I have yet to work out what the thread in the two holes is - the drawings don't help - I have a couple of screws that fit but I've no idea what their thread is either!

Item smaller than expected

Buon prodotto, robusto e affidabile, esegue il suo lavoro senza sorprese. Prezzo molto interessante

I am using these solenoids as part of a marble clock project, where they are responsible for sorting black and white marbles. They have performed exactly as expected and provide reliable, consistent movement every time they are activated. The build quality appears to be very good, and the push-pull action is strong enough for my application. Installation was straightforward, and they have integrated well into the overall design. If you need a dependable 12V solenoid for automation, sorting, or other mechanical projects, these are an excellent choice. In my case, they are helping keep a rather over-engineered marble clock running smoothly.

町内会のイベントで、クイズショーをやることになった。 本番まで、残り一週間。 ステージにはダイソーのピンポンブザーを五台並べた。 見た目は悪くない。 だが問題がひとつある。 誰が一番に押したのか、それが分からない。 ショーってのはな、そこが一番大事なんだ。 早押しはドラマだ。 ドラマには判定がいる。 だから俺は、PICマイコンをホストにして全部まとめて面倒を見ることにした。 このソレノイドは、 ピンポンブザーが上がる機構のストッパーリリースに使った。 ボタンを押しても、まだ上がらない。 ホストが許可して、初めて「ピンポン！」だ。 ショーは演出がすべてさ。 ベイベー。 発熱の話をしておこう。 他のレビューにもある通り、こいつは少し熱を持ちやすい。 でも俺の使い方は0.5秒程度の断続通電。 問題なし。 もし長時間通電するなら、そこは気をつけた方がいい。 機械にも休憩は必要だからな。 クイズショーはどうなったかって？ そんなの決まってる。 観客は笑い、ボタンは鳴り、勝負は白熱。 ――祭りは大盛りあがり、もちろん、大成功さ。

Fast delivery but smaller than expected

Veel speling en pen is krom. Geen aanrader.
