Description
The Omron D4NL-4CFA-B is a robust safety interlock switch with solenoid locking, designed for high-risk machine guarding applications. It features a positive-break mechanism (2NC contacts) that ensures immediate power cutoff when the door is opened, while the electromagnetic lock prevents access until the machine reaches a safe state. With IP67 protection and a durable metal housing, this switch is built to withstand harsh industrial environments and provide reliable safety monitoring.
