Solenoids typically operate at about 40 milliseconds with a load connected so a much “better” solenoid would be designed.

A proximity sensor would also detect the wood as it would need to be a capacitive sensor as opposed the ferrous/all metals or all materials (ultrasonic)!

If the blade guard had flesh sensing capability then it could be used to stop the blade and it would not need to be as fast as SS. Flesh sending technology has been around for decades (I designed my first one over 50 years ago) as it just uses the human body as a “switch” to close the circuit (a low current switch). However, there are some cuts that require removing the guard just as I am sure that there are instances where the SS needs to be disabled.

I also wonder how many LJs wear gloves while sawing lumber and does SS detect gloves? I think not, it would need to get to the flesh first!
