The six normally closed contacts provide dedicated circuits for door and lock monitoring. Selected NC contacts incorporate a certified direct-opening mechanism, supporting safety-related guard monitoring when the switch is integrated into a properly designed control system.
The mechanical-lock and solenoid-release arrangement is intended for applications in which a guard remains locked until an external control signal energizes the release solenoid. Terminal-block wiring and the adjustable operation-key insertion direction support practical installation in industrial equipment.
Applications
The Omron D4SL-N2RFA-D is used in industrial automation, factory automation, machine control, manufacturing equipment, robotic cells, packaging machinery, assembly systems, and other installations requiring monitored access through a movable guard or safety door.
It is also suitable for industrial control panels, OEM equipment, electrical equipment maintenance, automation components, and replacement parts programs where the specified contact arrangement, locking logic, conduit size, and connection method match the machine design.
