Aw 2745 Guard Shield

Available in a two-segment pair with a 600mm protected height or a three-segment pair with a 840mm protected height, these Type 4 PAC light curtains can be used as an opto-electronic fence or for access guarding at the entry or exit end of a machine process.

GuardShield features an integrated laser alignment system. The integrated laser alignment system is used to simplify set up and installation in longer range applications or when corner mirrors are used for multiple-sided guarding. The integrated laser alignment system is composed of two active laser elements located at the top and bottom of the GuardShield Safe 4 PAC; one is at the top of the transmitter and the other is at the bottom of the receiver. These visible laser beams are constantly powered but do not transmit light until a finger touches the transmitting element (a finger symbol is provided to indicate where the area should be touched to activate each transmitting element). Simply touching the element after alignment is complete will turn off the visible alignment beams.

GuardShield can be connected to the MSR 42 multi-function safety module to add functionality to the GuardShield Safe 4. Modes such as Start/Re-Start Interlock, External Device Monitoring, Start Release, and Two Sensor Muting can be configured in the MSR 42 by using the optical interface to configure the functionality.
