T Tulead 12V DC Solenoid Pull Push Electronic Actuator Micro Solenoid Electromagnet 5N Suction

Very reliable and works great!

To make it work correctly, leave about 3 mm empty space between the plunger and the object you want it to push. This separation will give the plunger time to get up speed and power otherwise it won't work. The solenoid draws 1.25 amps at 12 volts when operating.

I bought two of these for an engineering project and they average just under 3 newtons. I can still make them work, but they're not as advertised.

This solenoid is specified to have a travel of 10mm. It is actually less than 7mm. The operating current is specified as 600 mA at 12 volts, but is nearly twice that. I can't guess whether these discrepancies are the result of carelessness, or deception. Maybe the manufacturer can enlighten us.

Ordered ten of these, they all worked. The ends may loosen due to vibration depending on application, but other than that no problems at all.

Was hoping to use this for a door opener it really does not push anything it’s very weak I would not buy it again

I connected this to an 11 volt battery. It extends about 10 millimeters. It gets extremely hot very quickly if you keep it extended.

The product can very very hot and me become an issue if the environment cannot dissipate the heat!
