Why Choose the Pizzato NSD3ST1DMK-F40 Safety Interlock Switch?
The Pizzato NSD3ST1DMK-F40 is a compact RFID safety interlock switch with guard locking designed for reliable machine safety in industrial automation systems. As part of the proven Pizzato NS NS-series safety locking switch family, it provides secure actuator detection, electromechanical locking, and dependable safety feedback for modern machinery applications.
This model operates using a de-energised solenoid locking principle combined with low-level RFID coding (F40), ensuring consistent protection of machine guards during hazardous operations while maintaining simple and robust safety integration. It is engineered for compliance with EN ISO 14119 and widely used in industrial safety applications.
With its reinforced technopolymer housing, compact industrial footprint, and IP67/IP69K protection rating, the NSD3ST1DMK-F40 is suitable for robotic systems, packaging machines, conveyors, and OEM machinery requiring dependable guard locking and safety interlocking performance.
Key Advantages
- Low-level RFID-coded actuator system (F40 coding) for flexible actuator recognition.
- Solenoid guard locking with fail-safe de-energised release principle.
- Dual safety outputs (OS1/OS2) for redundant guard monitoring.
- Integrated diagnostic outputs for actuator and lock status (O3/O4 depending on configuration).
- Complies with EN ISO 14119 machine safety standards. ([pizzato.com](https://www.pizzato.com/en/catalog/NSD3ST1DMKF40.html))
- Suitable for integration into modern safety PLC and industrial automation systems.
Key Features
- Pizzato NS-series safety interlock switch with guard locking.
- Model: NSD3ST1DMK-F40.
- RFID low coding actuator recognition (F40).
- De-energised solenoid locking (fail-safe design).

Reliable Machine Guarding and Safety Control
The Pizzato NSD3ST1DMK-F40 ensures machinery only operates when protective guards are correctly closed. When the RFID-coded actuator is detected and locking is engaged, the safety outputs enable controlled machine operation under safe conditions.
If the guard is opened or the locking condition is removed, the system triggers an immediate safe stop. Integrated diagnostics support monitoring of guard status and actuator presence for safe integration into PLC-based safety architectures.
Typical Applications
- Industrial automation machinery.
- Robotic safety enclosures.
- Packaging and production lines.
- Conveyor and material handling systems.
- OEM machine building applications.
- General industrial safety guarding systems.
