Allen Bradley 440G-T27127 Guard Locking Switch

The AB 440G-T27127 is a TLS-GD2 guard locking safety switch designed for machine access control in safety-related applications. Operating on 24V AC/DC, it provides 2 normally closed (safety) and 1 normally open (auxiliary) contacts in a robust plastic housing. This model uses the operating current principle and offers a high clamping force of 2000 N to secure guards and protect personnel in hazardous zones.

With an ingress protection rating of IP67, quick-break contacts, and M20 conduit entry, the 440G-T27127 is built for demanding industrial environments. This model does not include an actuator, allowing for flexibility in actuator selection based on application needs.
