Allen-Bradley 440K-T11320 Safety Interlock Switch

The Allen-Bradley 440K-T11320 (440K-T11320) is an industrial safety interlock switch designed for machine guarding and safety monitoring applications across automated production lines. Operating as a critical component in safety control circuits, the device monitors the position of physical barriers, access gates, and safety enclosures to protect personnel from moving mechanisms and hazardous operating conditions. When an interlocked access point is opened during machine operation, the switch actuates to interrupt control signals, allowing safety relays or control systems to initiate an orderly machine shutdown or emergency stop. Built to withstand demanding factory environments, this unit provides reliable mechanical interlocking for industrial machinery, packaging equipment, assembly stations, and robotic work cells. Proper replacement and routine maintenance of safety interlock switches help preserve compliance with site safety requirements and prevent unauthorized override of protective barriers. The listed unit carries a recorded weight of 10 kg and integrates into standardized machine safety architectures. Verify system wiring, physical mounting arrangements, and matching part number designations before performing installation, maintenance, or replacement on existing Allen-Bradley safety hardware.
