Rockwell Automation introduced its new Allen-Bradley 450L Perimeter Access Control (PAC) GuardShield safety light curtains, designed to help production personnel work safer and more efficiently. Subject to risk assessment, light curtains can help to eliminate the need for hard guarding and gates while allowing more frequent, easier and safer access to hazardous
areas.
Designed for whole-body detection, PAC light curtains are typically positioned around an area or in front of a machine entry or exit that poses a moderate to high risk of operator injury. The light curtains help protect personnel and equipment by detecting the presence of people and objects within the guarded area.
The 450L GuardShield safety light curtains feature patented technology that allows each transceiver to be used as a transmitter or receiver via a plug-in module. The single-stick architecture helps to reduce the requirements for spare stock and offers an easier and more economical upgrade path should operational requirements change in the future. Other features that make the light curtains a versatile safeguarding solution for a wide range of applications include:
- An integrated laser alignment system, plug-in DIP switches and integrated muting options help to ease installation and configuration.
- Cascading plug-ins allow for serial connection of safety light curtains.
- Single-beam to four-beam options and protective lengths from 150 mm to 1050 mm cover a wide range of protection heights.
- Versatile mounting options help to simplify installation while a compact design helps to minimize the impact on a machine’s footprint.
The 450L safety light curtains are TÜV certified PLe, Type 4 IEC 61496-1/-2, SIL CL3 per the ISO 13849-1 and IEC 62061 standards.
