Allen-Bradley 440H-S34036 Safety Interlock Switch

The Allen-Bradley 440H-S34036 (440H-S34036) is a safety interlock switch designed for industrial machinery safety circuits and machine guarding applications. This device is engineered to monitor physical barriers, access gates, service doors, or safety enclosures, helping ensure that hazardous machinery stops or remains in a safe condition whenever a guard is opened or bypassed. As an integral component within automated production lines, packaging equipment, assembly systems, and material handling installations, it integrates into broader emergency stop and safety interlocking networks to protect operating personnel and industrial equipment. The switch unit features a robust construction suitable for industrial environments and has a recorded net weight of 10 kg. It serves as a direct replacement component for maintaining existing Allen-Bradley safety interlock systems, enabling maintenance personnel and facility operators to restore original safety functionality and system integrity during regular servicing or equipment overhaul.
