The Allen-Bradley 440K-MT55085 (440K-MT55085) is a safety interlock switch engineered for machine guarding and safety interlocking in industrial automation environments. This component functions within equipment safety circuits to monitor the status of movable guards, gates, access doors, and physical barriers, helping protect personnel and machinery during operating cycles. Designed for integration into industrial control and safety systems, the switch assists in preventing machine startup or interrupting hazardous machine motions when a guard is opened or improperly positioned. It serves as a direct replacement component for scheduled maintenance, hardware repairs, and system refurbishment across automated manufacturing facilities, assembly lines, and production machinery. With an approximate weight of 10 kg, the switch provides dependable physical presence and robust construction suited for demanding factory installations. By verifying part compatibility and system requirements prior to installation, operators can maintain the operational integrity and reliability of their safety interlock systems.
