HFeng Electromagnetic Lock Access Control 60KG/132lbs Electronic Magnetic Lock DC12V Fail Safe NC Mini Small Door Lock for Electric Security System

I picked up 3 of these, one to build into my workbench, and two to build into my welding table. They do an amazing job of clamping things in place while I grind, drill, etc., and don't require very much power so I was easily able to find old 12V 1A wall warts to power them. I don't expect the plastic body to hold up forever, but I don't care given the price.

These are fantastic, I use them to hold drawers shut in an RV.

This works as described. magnet seems a little weak but ok.

Magnet was shipped quickly, arrived promptly. Once installed, it hardly had any holding power even with the steel plate held tightly against the magnet. The instructions were in Chinese and I was unable to understand them but after reading the instructions for another magnet lock I discovered I needed to leave the steel door plate loose enough to allow it to lay flat against the magnet. If there are even a few hundredths of an inch space separation between the plate and any part of the magnet it will not work at all. Once I got that figured out it seems to work great, although the magnet runs hot to the touch. Maybe I should get some thermal conduction grease and install a heat sink?

Nicely constructed but the listing states "Working Current: 110mA". It actually draws closer to 260mA @ 12 vdc and runs too hot to touch! I didn't get around to using it until after the return period so I am stuck with it. Shopping for something better now and will be sure to test the current draw as soon as I get it this time!

It's simple, your shipping it to people in the United States, send instructions in English at a minimum, I could not get the electric magnet to engage. I requested instructions from the seller in English and they sent me instructions for a mounting bracket that was not included in it, I eventually figured it out after many YouTube videos, but should never have had to do that.

Shipped within the US, this item only included instructions and technical specs in Chinese. Not just negligent customer service, but also a safety risk where electronics are concerned. I will not purchase from this manufacturer again.The magnet is strong enough but must be mounted with extreme precision using more gear than was provided because it does not attract at all until the magnet and plate are literally touching.

After 30 min operating on a test bench the magnetic closure was 113 degrees F and rising. Had good closure strength, but the operating temperature is very concerning.
