What is the contact configuration of the Allen Bradley 440K-M22ABDT safety limit switch?
The Allen Bradley 440K-M22ABDT safety limit switch features a 2NC (Double Normally Closed) contact configuration. This means that when the switch is in its normal, unactuated state, both contacts are closed, allowing current to flow. When the actuator is triggered, these contacts open, signaling a change in the guard status.
