Looking for solenoid datasheet

Hi everyone, I just got this solenoid in amazon (I think the solenoid comes from China) and I'm looking for the datasheet but I can't find it. I need it to look for the Force-Voltage formula and the duty cicle required.

The seller don't answer, so that's not a solution.

Any of you know if there's a site where I can get this datasheet? maybe looking for it in browsers doesn't show up specific results.

Thanks for your help.

Many sites list it for sale but I found no data sheet. The sites do have the info below. What more do you need?

DC 12V 400mA 25N Force 10mm Stroke Push Pull Solenoid Electromagnet

As per Amazon



Size: JF-1039B Description:Push pull Type, linear motion, plunger spring return, DC solenoid electromagnet.Support DC 12V voltage, high power, pull push type, linear motion, is easy to install.DC solenoid electromagnet mainly used in vending machines, transport equipment, office facility, household appliance, mechanical, etc.Note:Please pay attention:As an actuating element of an automation equipment ,because the current is large, the single cycle can not be electrified for a long time.The best operate time is in 2 seconds.If the operate time is too long,the electromagnet temperature will rise.Too high temperature can affect the life of the electromagnet.Please take the electromagnet put down gently when you install it. The screw thread can make a corresponding change according to your demand. This product is small in size, please pay attention to in the process of using electricity, so as not to damage the electromagnet.

Thanks but it's not the same solenoid, mine is 2A.

But is it the same solenoid? Mine draws 2A instead of those 400mA

It means the coil's DC resistance is 12/2 = 6 ohms. For the 400mA version is 30 ohms.

For your solenoid the driving circuit should be capable of +/-12V (NOT 24V!) at 2A (since its bidirectional)

yep, I'm looking for the datasheet because I'm looking for this info (taken from another solenoid).
Sorry for the quality

How can you tell the solenoid is bi-directional?

From what I recall for a solenoid to be bi-directional there would have to be either two cores or a magnetized core.

Is there some subset of the data you require for you project? Or do you need the full chart.

I was thinking one could measure it if they used a standard electronic bathroom scale. A weight far above what the solenoid could pull.
Secure the solenoid above the weight, connect it to the weight, energize and see how far the scale drops.

In the link I posted (amazon one) it says
push pull (that's bidirectional right?)...and the model number is the same as the OP's...

It seems either I am wrong or the above link has the wrong info. The photo looks identical though...

That solenoid is a PULL TYPE with spring return, it is not direction controlled by the direction of current through it.

Activating it will always make it pull in against the spring.

AliEpress sell them as 6V, 12V and 24V units, and typical Chinesium, can't tell their PUSH from thier PULL.

Their description is just as usual a load of rubbish interspersed with the odd bit of valid data.

Tom... :grinning: :+1: :coffee: :australia:

This is from which supplier? The who discovered electromagnetism topic brings me here
