Allen-Bradley 440K-C21061 Safety Interlock Switch

The Allen-Bradley 440K-C21061 (440K-C21061) is a safety interlock switch designed for machine safeguarding, access door monitoring, and equipment safety applications in industrial automation environments. As part of an automated machine safety system, this interlock switch is engineered to monitor the position of movable guards, gates, and safety barriers. When an access door or safety guard is opened, the switch signals the safety control circuit to isolate power or initiate a controlled stop, preventing personnel from contacting hazardous moving machinery. Built for dependable operation in factory automation and manufacturing facilities, the 440K-C21061 provides essential interlocking protection for automated assembly lines, packaging machinery, robotic work cells, and material handling systems. The unit has a recorded weight of 10 kg and serves as a direct replacement component for scheduled maintenance, system overhauls, or repair of existing safety interlock installations. Utilizing genuine Allen-Bradley replacement hardware helps ensure proper mechanical fit, reliable switching performance, and continued operational integrity across plant safety architectures.
