GENERAL INFORMATION
GENERAL DESCRIPTION
The safety light curtains are optoelectronic multi-beam devices that are used to protect
working areas that, in presence of machines, robots, and automatic systems in general,
can become dangerous for operators that can get in touch, even accidentally, with mov -
ing parts.
The light curtains are intrinsic safety systems used as accident-prevention protection
devices and are manufactured in accordance with the international Standards in force
for safety, in particular:
