Light barriers

Light Curtains

What are light barriers?

Light curtains type 4 are used for access detection of people to machines and installations.

During an intrusion, the infrared rays between the transmitter and the receiver get broken. This will cause safety output signals to be generated which will stop the dangerous motion of the machine.
