Allen-Bradley 440L POC GuardShield Type 4 Integrated Laser Alignment Safety Light Curtain

Like its standard GuardShield counterpart, the GuardShield with integrated laser alignment safety light curtain is a self-contained, two box safety light curtain with DIP switch selectable operating modes. Available in both 14 mm and 30 mm resolutions in protected heights from 320 mm to 1600 mm these new GuardShield light curtains offer an easy alignment solution at installation or realignment if a light curtain or corner mirror is inadvertently misaligned during the course of operation. With integrated laser alignment, these GuardShield light curtains are offered with an option for connectivity to 1732DS ArmorBlock Guard IO modules. They are also configurable at the receiver by dip switch selection which allow the OSSDs to operate over a DeviceNet safety network. The constantly powered Class 1 eye-safe lasers are designed to switch from a low level of visible laser light to a highly visible laser light beam when the laser is temporarily blocked. The light beam reverts back to a low level of emission after 5 minutes or when temporarily blocked. GuardShield safety light curtains are ordered as pairs (transmitter and receiver) and are shipped under a single catalog number for ease of selection.
