Protective devices

Protective devices do not prevent access or entry into the machine's danger zone, but safely shut down the hazardous movements when the protective device is activated. Such protective devices include, for example, light beam devices, light grids, scanners, pressure sensitive mats or two-hand control devices.

Protection against unexpected start-up/restart of a machine

Two-hand control devices prevent injuries to hands or other body parts. The machine function/control command can only be triggered by using both hands, which are in a safe position during this operation.
