Ferrogard 440N Magnetic Safety Switch, Plastic, 24 V dc

Allen Bradley Guardmaster Non-Contact Switch

The Allen Bradley Guardmaster 440N series magnetic safety switch has a supply voltage rating of 24VDC at 1A current. This switch comes with FRS21 rectangular housings and a 6-Pin Micro quick-disconnect(QD) connection. It offers non-contact reliability with tolerance to misalignment. It is installed so that when a guard door is opened, the action of the magnetic actuator being removed from the switch opens the NC safety contacts, which are intended for the isolation of control power to a machine primary control element. It has protected safety contacts to ensure that it does not fail, unlike some other magnetic switch. It has internal non-resettable overload protection on the safety contact.
