Jokab Safeball™ Category 4 Two-Hand Control Device

The Jokab Safeball is a completely new approach to the design of one and two-hand safety devices. Safeball consists of a spherical ball containing two embedded push button switches, one on each side of the ball. By using this push button configuration, the risk of unintentional activation is minimized and the device is simple and ergonomic to use.

In the case where two-hand control is used, both Safeballs i.e. all four push buttons have to be activated within 0.5 seconds.

If one or more push buttons are released a Stop signal is given to the machine. In order to provide the highest level of safety the Safeball design provides the operator with a dual switching function and short circuit supervision in each hand. The design allows for comfort of use for all hand sizes and operation from numerous gripping positions.
