Allen-Bradley 440K-T11149 Safety Interlock Switch

The Allen-Bradley 440K-T11149 (440K-T11149) is a safety interlock switch designed for machine guarding and industrial safety monitoring applications. Operating as an essential component in protective interlocking systems, this switch helps safeguard personnel and machinery by monitoring the open or closed position of movable guards, gates, and safety barriers. When an access door or safety guard is displaced, the device changes state to prompt a stop command or prevent machinery restart, ensuring hazardous machine operations remain suspended during operator intervention. This Allen-Bradley safety switch unit integrates into industrial control architectures, safety circuits, and automated production cells alongside complementary safety relays and safety controllers. Built to withstand demanding factory environments, the unit is suited for manufacturing lines, automated assembly systems, packaging equipment, and material handling systems requiring reliable physical guard verification. With a recorded weight of 10 kg, the switch provides dependable mechanical engagement and continuous monitoring. Selecting the proper 440K-T11149 interlock switch ensures compatibility with existing hardware installations and maintains the integrity of plant safety infrastructure during maintenance, repair, and equipment overhaul procedures.
