Allen-Bradley 440N-G02096 Non-Contact Switch

Allen-Bradley Guardmaster 440N-G02096 Ferrogard Non-Contact Switch is a magnetically actuated safety interlock designed for guard doors, delivering a secure closed-door indication without any mechanical contact. Housed in a rectangular molded ABS red enclosure, it combines the switch and actuator in one compact unit and uses a 24 VDC supply with a single normally closed (1 NC) safety contact. A 4-pin Micro Quick Disconnect (QD) connector provides easy wiring, and the device is specified for up to 1 A of switching capability. This 440N-G02096 variant employs the FRS9 actuator concept within the Ferrogard family, offering reliable interlock functionality in standard guarding installations. Typical applications include safety gates and access doors on manufacturing lines, packaging machinery, and automated equipment where confirming the door is closed is essential before machine start or restart. As part of the Guardmaster Ferrogard range, it is designed to integrate with safety relays and controllers that monitor the interlock state, helping to meet common machine safety standards in industrial environments.
