Worked great. The magnet is strong enough that the switch detected it about an inch away.

Garage door doesn’t have to be perfectly aligned for it 2 make contact. Built well. Pays for itself over and over by not having to go out and Jack with the door to make contact.

It doesn’t have any description other than the Amazon listing Magnetic arm, but the seller was helpful in resolving any issue

If it gets stuck cause of the cold swing a strong magnet over the floor mounted sensore. That helps sometimes. It does not work well in the cold of SD

These will work anywhere you have a hardwired alarm system. We use DSC Neo everywhere, and these work just fine. Make sure you reinstall your end of line resistors so the panel recognizes this.Mounting was pretty easy and straight forward. Door mounted side is completely adjustable to make alignment of the two halves easy. My only complaint is if you use tap cons to mount these to a concrete floor, hex head tap cons will not fit flush into the circular grooves for the screws. I don’t see pan head working much better either. The heads are not high enough to pop a tire or anything but worth noting. The sensor is over to the edge far enough it’s mostly a non issue.

I use these for motor controls because they last longer than proximity switches. The magnet doesnt even have to touch it has to just be really close.

Required some careful consideration to determine exactly how I wanted to install these with my garage doors. There are no instructions or diagrams provided, so be prepared.The provided bracket could have worked, but I ended up locating them along the side of the doors for a cleaner looking installation. I screwed the sensor flat to the wall next to the door, and the magnet screwed to the side of the door.The sensor itself is extremely sensitive, which is great for this application. I noticed after test fitting the magnet, the residual magnetism I introduced onto the adjacent steel cable was enough to solidly trigger the switch even without the magnet. Pretty impressive.I've already got them wired up to a PLC which will email me when the doors are left open, so I'll know pretty quickly if these switches ever fail. So far so good.

The included mounting screws are made of the weakest chineezium metal.The heads of both broke off while trying to mount the sensor.I had to extract the broken off screws from the board.

This door contact served my purpose very well in a smart home environment. The door that it was installed on is frequently opened / closed and while other contacts have been damaged from extended usage- this contact has never failed to report door status in the 6 months that it's been in operation.I am very satisfied with the build quality and ease of installation. It comes with all the necessary mounting brackets and screws as well as extension plates if you need it on a garage door. Would recommend.
