Allen Bradley 440G-T27247 Guard Locking Switch

The AB 440G-T27247 is a robust TLS-GD2 guard locking safety switch designed for machine guarding applications that require solenoid locking and tamper-resistant interlocking. Operating on the quiescent current principle (power-to-release), this model is equipped with a 24V AC/DC solenoid and includes 2 normally closed safety contacts and 1 normally open auxiliary contact.

Featuring a high holding force of 2000 N, IP67 ingress protection, and a compact housing with a 12-pin M23 connector, the 440G-T27247 is well-suited for safeguarding hazardous machine access points in packaging, material handling, and robotic systems.
