There is no indication of the distance from the magnet to the sensor. The magnet isn't strong enough to hold.

later I ended up having to hook it up to a battery and slide the magnet past the sensor to see how close it has to be to activate it. The magnet flew out into the wild blue when I first started the engine. Now I have a sensor without a magnet. Trying to find a place to attach the sensor was a real bitch.

Pros

Application: Good product stability and strong anti-interference ability. It can be used for lathes, CNC, mowers, springs, etc. Measurement of different engine speeds.

Cons
