D4NL-4DFA-B OMRON

The D4NL-4DFA-B is a guard lock safety-door switch manufactured by Omron, designed to ensure operator safety by preventing access to hazardous areas when machinery is in operation. This robust switch features a durable plastic head and a mechanical lock mechanism, providing a secure and reliable interlocking system. The solenoid release operates on 24 VDC, allowing for remote unlocking and controlled access. It incorporates 2NC (Normally Closed) + 2NC (Normally Closed) slow-action contacts, enhancing safety by providing redundant signals for monitoring door position. The switch is equipped with an M20 conduit entry for easy and secure wiring. An integrated LED indicator, compatible with 10 to 115 VAC/VDC, provides clear visual status of the switch's operational state. This model is ideal for applications requiring a high level of safety and reliability in machine guarding. Its design ensures that the machine cannot be started until the guard is securely closed and locked, and that the guard cannot be opened until the machine has come to a complete stop. The D4NL series is known for its compliance with international safety standards, making it a trusted choice for industrial safety applications.
