MOTION CONTROL: Rockwell Automation has expanded its Allen-Bradley Guardmaster GuardShield safety light curtain line with the addition of three cost-effective options. Designed to provide end users with improved functionality, configuration flexibility and installation, the new safety light curtains include the GuardShield Safe 4 with an integrated laser alignment system, the GuardShield Cascadeable Micro 400, and the GuardShield Safe 4 PAC. The GuardShield Safe 4 safety light curtain is equipped with an integrated laser alignment system, allowing for simplified setup and installation. The GuardShield Cascadeable Micro 400 safety light curtain is a Type 4, “three-box” safety light curtain designed for small assembly machines in ambient operating environments where mounting space is limited. The GuardShield Safe 4 PAC light curtain is a self-contained, optically synchronized, “two-box” safety light curtain offering an expanded operating range.
