August 31, 2018 – Rockwell Automation has released the Allen-Bradley GuardShield 450L safety light curtain system to isolate robotic work cells from the rest of the plant with transceiver technology.

The integrated laser alignment system (ILAS) of the new GuardShield 450L-E reduces installation time by providing multiple visible laser points that 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 easy to integrate a GuardShield 450L-E system in hand and finger protection applications from 150 mm (5.9 inches) up to 1,950 mm (76.7 inches) in increments of 150 mm (0.5 foot).

After start-up, users can leverage advanced features and functionality, including cascading, built-in muting and blanking.


The advanced 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 like four-sensor or two-sensor with L- and T-configuration and override function can be selected as well as reduced resolution or teach-in fixed blanking.
