Poka Yoke Air Impulse Tools with Pressure Controlled Shut-off

The Yokota Poka-Yoke-Plus impulse screwdriver system ensures optimum clamping force through electronically controlled shutdown. The control unit monitors the different air pressures at the inlet of the air motor during idle and screwing. The control unit registers when the screw head makes contact and sends a signal to the timer to shut down. The time delay can be set for hard or soft screw connections. In addition, the system monitors for premature release of the trigger and also detects any double screw connections.
