Allen-Bradley 440E-L13140 Cable Pull Assembly

Allen-Bradley 440E-L13140 Guardmaster Lifeline 4 Cable Pull Switch is a stainless‑steel rope‑pull safety device used in machine guarding to stop equipment when the lifeline is pulled. This Lifeline 4 model supports a system length of up to 75 meters and provides a dual‑channel safety interface with two normally closed safety contacts plus two normally open auxiliary contacts, all wired through a 12‑pin M23 connector for robust industrial connections. It employs direct opening action to deliver immediate signaling to the safety controller, making it well suited for long‑reach emergency‑stop installations where a pull‑cable interface is required in demanding environments. Typical applications include safeguarding conveyors, presses, and automated lines in manufacturing settings, where a mechanical pull on the lifeline must swiftly initiate a safe shutdown of the equipment. Built to withstand the rigors of industrial use, the 440E-L13140 integrates into Lifeline 4 safety networks, enabling reliable interconnections between the rope/pull mechanism and the controller while maintaining clear separation between safety and supervisory circuits.
