Allen-Bradley 440K-T11090 Saftey Guard Locking Switch

Description

The Allen‑Bradley 440K‑T11090 is a robust guard locking switch from the Guardmaster Trojan 5 series. This safety interlock device is engineered for your industrial safety needs, featuring a keyed tongue mechanism that ensures the guard cannot be opened during machine operation. It includes two normally-closed safety contacts to interrupt hazardous motion and a normally-open auxiliary contact for signaling. With a self-ejecting, tamper-resistant actuator and rotatable head design offering four actuator entry options, it’s adaptable to a wide range of guard configurations. Constructed from durable glass-filled PBT, this switch is IP67-rated, providing excellent resistance to dust and water ingress. It supports M20 conduit connection for secure wiring, and its break-before-make contact action enhances safety when switching. Ideal for automation and machinery protection, it fits tightly within safety standards while optimizing installation flexibility.
