Allen-Bradley 5-GD2 Gate Guard Door Interlock

Allen-Bradley Guardmaster Atlas 5-GD2 Gate Guard Door Interlock is a tongue-operated guard-locking safety switch designed to interlock guarded access doors on industrial equipment. The Trojan 5-GD2 variant is described as a positive-mode, tongue-operated interlock switch in Rockwell Automation installation literature and is cataloged in distributor listings as Trojan 5 GD2 or Guardmaster Trojan 5 GD2. An available lock-off accessory (TLS-GD2) lets maintenance staff secure the guard door with a padlock during service, aligning with common safety practices for locked doors in guarding applications. This interlock functions as part of the machine safety system: the door must be closed (and the interlock engaged) before the machine can start or operate, with integration typically into safety relays or controllers to monitor door status and interlock condition. The 5-GD2 is part of the Guardmaster Atlas family, a line of robust guard-locking switches used in demanding guarding environments, and is referenced in multiple catalogs and installation manuals under the GD2 designation for Atlas/Guardmaster guarding solutions.
