Safety Interlock Switches Without the Compromise

9/19/2025

When choosing safety devices for currently operating hazardous machinery, you don’t want to compromise your production output with lengthy shutdowns and installations. Allen-Bradley® by Rockwell Automation® offers a wide range of safety interlock switch configurations to fit different applications, including guard locking, hinge and interlock switches. These devices are easy to install, minimizing machine downtime and keeping your equipment producing safely.

Connecting safety interlock switches and other devices via GuardLink® 2.0 (safety protocol), enables you to pull advanced diagnostics and safety information (such as control device status) to an HMI with CIP Safety™ over EtherNet/IP. Installing your series-connected safety devices with GuardLink-enabled connection taps also reduces wiring time, making for even shorter installations.
