Super low price and they work flawlessly. I used these to replace some magnetic shaft speed sensors on a Flexicoil seed cart. Pretty sure they will work well for their intended purpose too!
Worked better than my old one that I replaced as it was smaller and didn't work well with door.
This one was larger and happy with results for sliding doors
I purchased these to update the old ones that were damaged when I had my windows replaced. I used double sided tape to adhere them to the windows as I didn't want to use screws. I was under the impression that these came with the double sided tape, but the did not so I used Automotive Moulding tape which worked like a charm.
