When the system senses contact with a person’s skin, it triggers an incredibly fast mechanism that immediately stops the saw blade’s rotation. Alongside stopping the blade, the system also swiftly retracts it beneath the saw’s surface, preventing any further harm. By rapidly halting the blade’s movement upon detecting contact with flesh, SawStop helps minimize the risk of serious accidents and provides a crucial layer of safety for users working with power saws.

The Technology behind SawStop

SawStop is a revolutionary technology that has transformed table saw safety. By incorporating advanced electronics, sensors, and a high-speed braking system, it effectively reduces the risk of serious injuries caused by contact with a spinning table saw blade.

SawStop’s technology is based on the principle of electric current sensing. The saw’s blade carries a small electrical signal, and when a conductive material (such as human skin) comes into contact with the blade, the electrical signal changes. This change is detected by the saw’s electronic control unit, which triggers the braking system to stop the blade’s rotation in a fraction of a second.

The heart of SawStop’s technology is the safety system, which consists of three crucial components:

  • The Blade
  • The Sensor
  • The Brake

The blade used in a SawStop table saw has a specially designed tooth pattern that rapidly increases the electrical conductivity of the blade when contact is made with a conductive object. This change in conductivity is what triggers the safety system.

The sensor is responsible for detecting the change in conductivity and sends a signal to the electronic control unit, instructing it to stop the rotation of the blade. The sensor is highly sensitive and has a response time of just a few milliseconds, ensuring that the blade stops almost instantly upon contact.

The brake is a crucial component that brings the blade to a halt. It consists of an aluminum brake pawl, which is spring-loaded and positioned just behind the blade. When the sensor signals the electronic control unit to stop the blade, an electrical current is sent to a solenoid, which releases the pawl into the blade, embedding it and causing it to stop.

The braking system is designed to be a one-time use mechanism. Once the brake is engaged and stops the blade, it must be replaced with a new brake cartridge before the saw can be used again. This ensures that the safety system is always fully functional and ready to protect against accidents.

Overall, the technology behind SawStop is a remarkable advancement in table saw safety. It effectively detects and prevents potentially life-threatening accidents by rapidly stopping the blade upon contact with human skin or other conductive objects.
