Danger zone guarding
Danger zone guarding enables a large protection area on machines that must remain accessible. The Scanner is applied as a stop-activating
and presence-detecting protective device. The Scanner’s PF is set up horizontally in front of the machine hazard.
Danger zone guarding can also be applied to guard areas under or at the rear the machine.
