Baomain Solenoid Electromagnet BM-0530B DC 12V 10mm 5N 950mA Push Pull

Stronger than expected. The pull strength is directly proportional to input voltage. But, it does have a small spring, so the push/return is relatively weak. While the spring is adequate, even a small resistance can prevent it from fully returning; however, the spring looks easy to replace with a stronger one, if necessary.

It works, but is weak as others have reported. Understandably, the forced of a solenoid is not linear over its entire stroke. The pull force is very weak at the beginning to stroke, and the stated force is likely applicable to just last few millimeters. One irritating design flaw is the location of the screw holes on the housing, which is located facing the center of the solenoid coil. If the mounting screws are too long, they will gouge into the solenoid coil.

Doing exactly what it is was described to do

The DC resistance is about 10 ohms so at 12V it draws 1.2 amps.At that voltage and current the force is less than two newtons.There is no way that it will ever have a force of 5N.It got too hot to touch.It is a mechanically nice little unit but it won't produce anywhere near 5N at 300ma.It may work OK for applications requiring about one newton.Vern

It takes 1.7amps instead of the 950mA in the description and the springs I got are very worn out. But overall still does the job

Buen producto

Works as advertised.

I really should have paid attention to the size. It is tiny. I will need to find a use for it because it won't work with what I intended. 5n / 1 lb but doubtful.
