Advanced light curtain system improves robot cells' flexibilityRockwell Automation is promoting its recently launched Allen-Bradley GuardShield 450L safety light curtain system, which is said to be particularly useful for robot cell entry points. According to the company, innovative transceiver technology makes the GuardShield 450L safety light curtains flexible and cost-effective.

Manfred Stein, global product manager, Safety Light Curtains, Rockwell Automation says: “Users will see significant advantages throughout the lifecycle of the new light curtain system, but especially during installation and operation.”

The Integrated Laser Alignment System (ILAS) of the new GuardShield 450L-E reduces installation time by providing multiple visible laser points that optimise setup with a simple touch of the ILAS symbol on the front window of the stick. Plus, the compact design and full-length protective field make it easy to integrate a GuardShield 450L-E system in hand and finger protection applications from 150mm (5.9 inches) up to 1950mm (76.7 inches) in increments of 150mm (0.5 foot).

After start-up, users can leverage advanced features and functionality, including cascading, built-in muting and blanking, to enhance flexibility while maintaining the highest level of safety.

The advanced muting and blanking functions of the GuardShield 450L-E light curtain are easily set up through DIP switches located on the dedicated plug-in modules. Common muting set ups like 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 inherent flexibility of the GuardShield 450L transceiver design help to simplify engineering logistics and minimise the stock required to address the full range of applications.
