OMRON D4SL-N4EDG-D Guard Lock Safety Door Switch

The OMRON D4SL-N4EDG-D (D4SL-N4EDG-D) is a guard lock safety door switch engineered for industrial machinery protection and machine safeguarding applications. Designed as part of the OMRON D4SL-N series of safety door switches, this device monitors the open or closed position of movable machine guards, access doors, gates, and protective enclosures. By reliably interlocking physical barriers with industrial automation controls, the switch prevents unauthorized or hazardous access to dangerous operating areas while equipment is running and ensures machines cannot restart while protective guards remain open. Built for dependable integration in industrial environments, the D4SL-N4EDG-D supports safety interlock systems across automated manufacturing cells, robotic installations, assembly lines, packaging machinery, and material handling systems. The unit has a listed net weight of 10 kg and is engineered to maintain operational integrity in demanding industrial settings. As a replacement or spare component, this safety switch allows maintenance technicians to restore protective interlock functionality, support plant safety compliance, and maintain reliable personnel protection across automated production systems.
