D4NL‑4FFA‑B OMRON

The OMRON D4NL-4FFA-B is a compact plastic-cased safety door switch with a solenoid interlock, designed for machine guarding applications. It features a 3NC/1NO contact configuration, ensuring reliable safety monitoring. The integrated solenoid operates at 24 VDC and is configured for power-to-release, meaning the guard remains locked when power is removed, enhancing safety. It includes an LED indicator for status visualization and M20 conduit entries for wiring. This model requires a separate actuator key (e.g., D4NL-K1, D4NL-K2, etc.) for operation and is compliant with international safety standards, providing a robust solution for preventing access to hazardous areas until machinery is safely shut down.
