SawStop Saws Detect Contact With Skin
The blade carries a small electrical signal, which the safety system continually monitors. When skin contacts the blade, the signal changes because the human body is conductive. The change to the signal activates the safety system.

How It Works

​1. Monitor & Detect

  • The blade carries a small electrical signal.
  • When skin contacts the blade, the signal changes because the human body is conductive.
  • The change to the signal activates the safety system.

​2. Brake Activation

  • An aluminum brake springs into the spinning blade, stopping it in less than 5 milliseconds!
  • The blade's angular momentum drives it beneath the table, removing the risk of subsequent contact.
  • Power to the motor is shut off.

​3. Reset
Resetting the saw yourself is easy. Simply inspect the blade (and change if damaged) and replace the brake cartridge, and your saw is operational. The entire process takes 90 seconds and you're back to work.
