Two channel switching in
each hand
Safeball™ consists of a spherical ball containing two embedded
pushbutton switches, one on each side of the ball. By using this
pushbutton configuration, the risk of unintentional activation is
minimised and the device is simple and ergonomic to use.
Safeball™ can be utilised for either One hand (one Safeball™)
or Two hand (two Safeballs™) applications. In either application,
and in order to meet the required level of safety, the Safeball™
switches are monitored by specified/certified ABB Jokab Safety
Safety relays.
In the case where Two hand control is used, both Safeballs™
i.e. all four pushbuttons have to be activated within 0.5 seconds.
If one or more pushbuttons 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.
EachSafeball™ is ergonomically designedandhas both its cover
and actuator made of environmentally-friendly polypropylene. The
design allows for comfort of use for all hand sizes and operation
from numerous gripping positions. Mounting of the Safeball™ is
also very flexible allowing the device to be mounted in the most
ergonomic position for the operator.
When can a two hand or one hand
control be used ?
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.
SAFEBALL™
Unique world wide two hand device
A one hand control device can be used when the operator cannot
reach the hazardous area with his/her free hand or on less danger-
ous machines.
Highest safety level
The Safeball™ is certified by Inspecta in Sweden for use as a Two
hand control device, when used with a JSBR4 ABB Jokab Safety
Safety relay or Pluto Safety-PLC, in accordance with the highest
safety level in standard EN 574 (type IIIc).
Two hand device adapted for AS-i
The two hand device, Safeball also comes in a version adapted for
direct attachment to the AS-i bus.
