Allen-Bradley 440KT1146 Industrial Relay Module

Allen-Bradley 440K-T1146 Trojan 6 Tongue Interlock is a Guardmaster safety interlock switch designed to secure guarded access points on industrial equipment. This safety device is installed on machine access doors to prevent operation whenever the guard is open, providing a monitored stop condition through a safety-relay circuit. The Trojan 6 tongue design provides a robust latch interface for reliable door detection and is intended for integration with Rockwell Automation Guardmaster safety systems to help meet machinery safety standards in automation environments. Typical applications include safeguarding conveyors, presses, packaging lines, and other automated machinery where access to the danger zone must be prevented during operation. By pairing the interlock with compatible safety relays, the system enables safe reset and release only after a verified safe condition is restored, contributing to compliant machine guarding and improved operator protection. The catalog number 440K-T1146 identifies the Trojan 6 tongue interlock variant within Allen-Bradley’s Guardmaster family, manufactured by Rockwell Automation.
