Hall sensor for scooter motor
I ordered these to try and bring back life to my scooter hub motor. I couldn't get it working right but I dont think it was the hall sensors problem. Although these dont come insulated which could very well have been why they didnt work for me. So I unfortunately had to figure out a different option.

Apparently works down to 3.3v
I don't think I noted the voltage range (4-24v) when i purchased these to work with my 3.3v logic board, but luckily they still work! Perhaps it changes the sensitivity characteristics or something else, but it works great for my purpose. I have 2 of them connected in parallel for an "emergency stop" function. In normal operation, magnets are in place over the sensors, maintaining an open drain and LOW signal pin. Only if BOTH magnets are removed from their slots (via a pull-cord), the signal pin is pulled high by the pullup resistor, signaling an emergency.

Work great for ignition pickup sensors on small gasoline engines
Almost an exact replacement for an RC airplane DLE 20 engine electric onboard starter pickup device. The wires broke on the original one. It was a simple matter to heat the epoxy holding it in place and removing it. Wired a new one up and epoxied it in place. Fairly easy job, and a whole lot cheaper than a new starter. I would imagine this would work for most gasoline RC engines.

Love, Love, Love these little guys.
built this elaborate busy box for my grandson with just under 20 of these sensors. Each one is flawless and durable. Paired with small magnets and covered with epoxy then connected to arduino. Perfect. Just remember they do have a polarity so be sure to have the magnet positioned to trigger the sensor.

Did not work well for me.
Not sure to chock it up to user error or not a great product, hence three stars. Sensitivity seemed off.

Good good
Pretty good for the price. Detecting up to an inch away with just a small neodymium magnet.

Worked great
Nice little set used for ironman helm 3d printed and magnetic open switch this worked out great for me.
