Allen-Bradley 440E-L13133 Cable Operated Safety Switch

The Allen-Bradley 440E-L13133 Cable Operated Safety Switch is a rugged cable-pull safety interlock designed to monitor access points on industrial machinery and reliably disable equipment when safety conditions require it. Operating at 24 VDC with two normally closed contacts (2 A max), it features a 15 m cable for flexible installation, a panel or surface mount, and an IP67-rated stainless-steel housing with a 1/2" NPT conduit size for robust, harsh-environment use; it withstands -25°C to 70°C and is actuated by cable pull. This device is widely used on conveyors, safety gates, emergency stop circuits, and machinery guarding systems, and it meets Cat 4, PL e (ISO 13849-1) safety standards.
