Product Overview
The Omron D4NL-4CFG-B Safety Door Switch is a robust, integrated safety solution designed for reliable access control and personnel protection on factory machinery, industrial robots, and automated equipment. This unit combines a safety door switch with a powerful electromagnetic lock (EM lock) that securely holds protective doors, gates, or guards closed during machine operation. Operating on a 24VDC power supply, it features heavy-duty DPST (Double-Pole Single-Throw) contacts rated for 10A, ensuring dependable circuit interruption when the door is opened. With a high IP67 protection rating, the D4NL-4CFG-B is resistant to dust ingress and temporary immersion, making it suitable for harsh industrial environments. Its design meets key safety requirements by providing a positive-guided mechanism and a direct-opening action, helping to achieve safety integrity levels for machine guarding applications. This switch is essential for compliance with safety standards and protecting operators from hazardous machine motion.
