How do Light Curtains work?

Safety light curtains work via a sender pole transmitting the infrared light to a receiver pole. If an object passes through the light barrier and interrupts the transmission, it causes the machine to stop. This means there is appropriate safeguarding in place for the people around the hazard, thereby reducing susceptibility to injury and harm.
