Rockwell Automation released its updated Advanced Light Curtain System, the new Allen-Bradley GuardShield 450L-E. Using the company’s Integrated Laser Alignment System (ILAS) with GuardShield 450L-E can help to reduce installation time by providing multiple visible laser points that help to optimize setup with a touch of the ILAS symbol on the front window of the stick. The compact design and full-length protective field make it easier to integrate a GuardShield 450L-E system in hand and finger protection applications from 150 mm (5.9 inches) up to 1950 mm (76.7 inches) in increments of 150 mm (0.5 foot).
After start-up, users can leverage additional GuardShield 450L-E features and functionalities, including cascading and built-in muting and blanking, to help enhance flexibility while maintaining a high level of safety.
The muting and blanking functions of the GuardShield 450L-E light curtain are set up through DIP switches located on the dedicated plug-in modules. Common muting set ups, such as 4-sensor or 2-sensor with L- and T-configuration and override function, can be selected as well as reduced resolution or teach in fixed blanking. A cascading plug-in can also be installed for series connection of additional GuardShield 450L Safety Light Curtain systems, enabling multi-sided machine guarding.
All these special functions, combined with the flexibility of the GuardShield 450L transceiver design, help to simplify engineering logistics and minimize the stock required to address a range of applications.
