Allen-Bradley 440K-T11429 Safety Interlock Switch

The Allen-Bradley 440K-T11429 (440K-T11429) is a safety interlock switch designed for machine guarding and industrial safety applications. As an essential component in protective interlocking systems, this switch is deployed to monitor the open or closed status of movable machine guards, access doors, safety gates, and barriers. By interfacing with safety circuits and monitoring devices, the interlock switch helps prevent hazardous machine operation when protective access points are opened or compromised. The unit has an approximate weight of 10 kg and is engineered to withstand demanding operating conditions across automated manufacturing, material handling, packaging, and assembly lines. It serves as a direct replacement part for maintenance, repair, and overhaul tasks where part number 440K-T11429 is specified. Integrating this safety interlock switch into existing safety architectures supports operational reliability and personnel protection across industrial automation environments. Verify application requirements and mounting configurations before installation to ensure compatibility with your safety control setup.
