Allen-Bradley 440K-T11280 Safety Interlock Switch

The Allen-Bradley 440K-T11280 (440K-T11280) is a safety interlock switch designed for industrial machinery and automated equipment protection. As part of machine safety systems, this switch functions to monitor the position of movable physical guards, access doors, gates, and protective covers. When a guard or safety barrier is opened, the interlock mechanism operates to interrupt control circuit power or provide status feedback, preventing hazardous machine operation and safeguarding personnel during operation, maintenance, and routine servicing. Engineered for dependable integration within factory automation environments, the 440K-T11280 supports standard industrial safety circuits and control architectures. It features a robust design suitable for demanding manufacturing conditions, with an approximate weight of 10 kg. Typical applications include manufacturing cells, packaging systems, assembly lines, and material handling systems where interlocking guards are required to maintain secure operating conditions. This unit serves as a direct replacement component for servicing existing machinery, helping facilities maintain operational safety standards, reduce unexpected equipment downtime, and support reliable safety interlocking across automation workflows.
