The Allen-Bradley 440K-T11212 (440K-T11212) is a safety interlock switch designed for industrial machine guarding and personnel protection applications. Engineered by Allen-Bradley for integration into automated systems and production machinery, this safety switch monitors the position of physical barriers, access gates, and safety doors to protect operators from hazardous machine motion. When an interlocked access door or protective guard is opened, the safety interlock switch isolates power to hazardous machinery, preventing unauthorized restart until the protective enclosure is closed and properly secured. This component features rugged construction suitable for demanding factory environments, assembly lines, packaging machinery, and industrial automation equipment. With a catalog weight of 10 kg, the switch provides dependable physical interlocking in safety monitoring circuits, helping systems meet plant safety standards and operational integrity requirements.
