GuardShield Safe 4 is a Type 4 safety light curtain in a two-box configuration with ON/OFF functionality that comes with an integrated, visual laser alignment system that makes it easier to align the transmitter with the receiver during installation and operation. The alignment laser activates by simply touching the target, which in turn initiates a Class 2 laser beam. The system does not need a dedicated safety controller and can be used with many standard safety controllers.For more information, click here.
