Rockwell Automation launches new Allen-Bradley 440G-MZ Guard Locking Switches


New Allen-Bradley 440G-MZ Guard Locking Switches from Rockwell Automation simplify installation and troubleshooting with, no reduction in safety integrity. The smart safety solutions use GuardLink technology, a safety-based communications protocol that provides access to diagnostic information and eases integration into a Connected Enterprise.

The new 440G-MZ safety switches help protect personnel and are suitable for use with many types of guard doors, including full-sized guard doors that allow full-body access to safeguarded areas, where high holding forces and wide tolerance to guard misalignment are commonly required.

The 440G-MZ safety switches are TÜV-certified up to SIL 3, PLe, Cat 4, providing the highest level of safety for door position monitoring and guard locking.

The safety switches can be used, in applications like robotic assemblies and packaging machines surrounded by perimeter fences with guard doors for full-body access. They can also be used, with bottling and other machines that have built-in full-sized doors, as well as with small-to-medium CNC machines.
