SawStop saws are equipped with a safety system to stop the blade within 5 milliseconds of detecting contact with skin. 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. A heavy-duty aluminum brake stops the blade. The blade stops within milliseconds of detecting contact, quicker than a car airbag deploys. During this time three things happen: 1.An aluminum brake springs into the spinning blade, to stop the blade. 2.The blades angular momentum drives the blade beneath the table, removing the risk of subsequent contact. 3.Power to the motor is shut off. Resetting the saw is easy. It takes about five minutes to replace the $69 single-use brake cartridge and blade. SawStop® table saws are the most advanced saws in the world, setting the standard for table saw safety. SawStop saws are equipped with a safety system that detects when someone accidentally contacts the spinning saw blade, and then stops the blade in milliseconds. In most cases, such an accident would result in just a nick on a SawStop saw, instead of the devastating injury which would likely occur on an ordinary table saw. The SawStop safety system includes an electronic detection system that detects when a person contacts the blade. The system induces an electrical signal onto the blade and then ...
