New Category 4 Two-Hand Control Device.
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.
When can a two-hand or one-hand control be used?
A two-hand control is used when it is necessary to ensure that the operator 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' 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.
Highest Safety Level
The Safeball is certified by DNV (Inspecta) in Sweden for use as a two-hand control device, when used with a JSBR4 Jokab Safety Relay or Pluto Safety PLC, in accordance with the highest safety level in standard EN 574 (type IIIc) and EN 954-1/ISO 13849-1 (safety category 4).
JSTD25 Two-Hand Control Station with Safeball
With a JSTD25 you have a prepared two-hand station that is easy to install, while utilizing the good ergonomics of the Safeball. There are several variants to meet differing needs. All versions meet EN574, EN954-1 and EN13849-1 and are supplied with the internal connections made to simplify installation.
