Allen-Bradley 440G-T27127 Guardmaster TLS-GD2 Guard Locking Safety Switch 24V AC/DC
440GT27127
The Allen-Bradley 440G-T27127 is a Guardmaster TLS-GD2 tongue-operated guard locking safety switch designed to keep machine guards locked closed until power is isolated, and to keep power isolated while the guard is open. This power-to-lock model operates on a 24V AC/DC solenoid and provides a high locking force to secure guard doors in demanding industrial applications.
The TLS-GD2 features positive-mode operation with 2 N.C. safety contacts and 1 N.O. auxiliary contact, plus 1 N.C. and 1 N.O. solenoid monitoring contacts. Housed in a rugged red glass-filled polyester enclosure with M20 conduit entry, it is well suited to guard door interlocking on machinery, conveyors and production equipment.
Note: Actuator is not included and must be ordered separately to suit your application (standard, fully flexible or semi-flexible GD2 actuators).
