440G-L07255, Allen Bradley Guardmaster 440G-L Solenoid Interlock Switch Power to Unlock 24 V ac/dc

Allen Bradley Guardmaster Safety Interlock Switch

The Allen Bradley Guardmaster atlas 5 positive mode, tongue operated safety interlock switch has a supply voltage rating of 24VAC/DC. It has 2NC/1NO contacts. This interlock switch has a machine guard closed until power is isolated to ensure that it remains that way when the guard is open. It is a heavy-duty switch and locking mechanism is designed to withstand forces up to 5000N (1124lbs). A unique feature of this switch is a patented self-aligning head that tolerates actuator or guard misalignment, making it particularly useful for heavy machine guards. It is designed for machines that do not stop immediately or where premature interruption of the machine could cause damage to tooling and components or cause an additional hazard.
