Rockwell Automation is introducing new presence-sensing safety light curtains. The Allen-Bradley 450L GuardShield safety light curtains are designed to help improve productivity and increase efficiency while providing personnel safety. This light curtain is designed to provide CIP Safety over EtherNet/IP, reportedly the first light curtain to be able to do so.
CIP Safety over EtherNet/IP helps to enable smart safety within a Connected Enterprise and to provide enhanced data from the plant floor. The 450L GuardShield light curtains support linear, star and DLR networks and are suited for applications where safe, easy and frequent access to the machine is required.
The 450L safety light curtains are unlike traditional safety light curtains, which are based on separate transmitter and receiver units. Patented technology allows each transceiver to be used as a transmitter or receiver via a newly designed plug-in module. The 450L-E option provides more advanced functionality, including integrated laser alignment, cascading, blanking and integrated muting.
The 450L safety light curtains are TÜV certified PLe, Type 4 IEC 61496-1/-2, SIL CL3 per EN ISO 13849-1, and IEC 62061.
