Frequently asked questions

How does the Allen Bradley 440K-M22AEDT safety limit switch contribute to machine safety?

The 440K-M22AEDT switch acts as a gatekeeper for machine operation. When a guard or access door is closed, its contacts remain in a state that allows the machine to run. If the guard is opened, the actuator is pushed, changing the contact state and signaling the safety system to stop the machine, thereby preventing potential hazards.
