Safeball
Safeball™ consists of a spherical ball containing two embedded pushbutton switches, one on each side of the ball. To be able to start and operate a machine both buttons must be activated..
For a two-hand control device one needs to have a Safeball for each hand to be able to operate a machine and all the four switches have to be activated within the simultaneous requirement (0.5 seconds). The safeball is the first two-hand control device that is two-channel all the way out to the hand.
A Two hand control can be used when it is necessary to ensure that the operator is outside and must be prevented from reaching into the hazardous area. If the operator decides, after the start signal has been given to the machine, to make an ‘after-grasp’ i.e. try to adjust the part that has been placed into the machine, then a dual stop signal is given to the machine. A one hand control device can be used when the operator cannot reach the hazardous area with his/her free hand or on less dangerous machines..
Safeball with built-in AS-i safety node
Safeball is also available in a version adapted for direct attachment to the AS-i bus.
