Allen-Bradley® GuardShield™ 445L to 450L-E Safety Light Curtain

The Allen-Bradley® GuardShield™ 450L Safety Light Curtains from Rockwell Automation include Basic and Enhanced models both available in finger or hand resolution. 450L POC offers the full functionality of 445L in a similar profile. Like the 445L, the 450L features an integrated laser alignment system. Another advantage of the 450L family is that it offers end-to-end protection and has no dead zone. 

The Allen-Bradley® GuardShield™  450L-E Safety Light Curtains from Rockwell Automation are based on a unique patented transceiver technology which allows each stick to be used as a transmitter or as a receiver. The full functionality of a transceiver is provided by plug-ins inserted at the bottom of the sticks. By using only one stick type with the optimal plug-ins selected based on the requirements of the application, the GuardShield 450L portfolio is a simple, cost effective solution that offers enhanced flexibility while maintaining the highest level of safety. 

The enhanced GuardShield 450L-E light curtain system is also ideal for applications requiring advanced functions such as integrated laser alignment, cascading, blanking, and integrated muting.
