Allen-Bradley 440H-E22043 Safety Interlock Switch

The Allen-Bradley 440H-E22043 is an industrial safety interlock switch designed for machine safeguarding, monitoring, and personnel protection across automated industrial environments. Operating as a critical safety component within industrial control systems, this device ensures machinery cannot operate under hazardous conditions when protective guards, access doors, or perimeter gates are open. It is engineered for integration into automated production lines, packaging equipment, assembly systems, and material handling machinery to help maintain operational safety compliance and protect operating personnel from mechanical hazards. This safety interlock switch carries a net weight of 10 kg and serves as a direct replacement component for scheduled maintenance, preventative overhaul, and emergency repair tasks. By reliably verifying the open or closed state of access points and machine barriers, the switch helps prevent unauthorized access and inadvertent machine startup during active operations. The Allen-Bradley 440H-E22043 provides dependable interlocking performance in demanding industrial facilities, supporting ongoing plant safety, minimizing unscheduled production downtime, and maintaining standard industrial safety architectures.
