Worked perfectly.
Very pleased with the sensors. Placed on a custom built laser engraver and they detected the metal flag. Reliability and repeatability in all four.

Will do the job.
met my requirements, but I wish the wire leads were a little longer.

Works great and as intended.

Nice adjustment hardware
Very well made and comes with a mounting bracket that allows easy spacing adjustment for the sensor. Remember that sensing distance for steel is only 4mm which is what I measured.

Good construction quality
The functionality is perfect and very good quality (screws included) I don't give 5 stars because it says it's a set of 4 and only 2 arrived. I tried to claim it but couldn't find the option to talk to the seller.

They simply don't work.
Save your money, these do not work.
J**.
Reliable triggering
The repeatability is very good with these, standard mounting pattern, clearly marked and they have a nice visible indicator. Make sure you get the right kind, these ones trigger on approach detect, if you need to invert that signal then grab the other type or use an inverter if you can deal with delay added by the extra step. The devices are fully potted in epoxy and include a sturdy mounting bracket for distance adjustment.
