Why Choose the Pizzato NSD3ST1SMK-F40 Safety Interlock Switch?
The Pizzato NSD3ST1SMK-F40 is a compact RFID safety interlock switch with guard locking designed for industrial machine safety applications requiring reliable guard monitoring, controlled access, and consistent safety feedback. It belongs to the proven Pizzato NS NS-series safety locking switch family, widely used in OEM machinery and automation systems.
This model operates using a de-energised solenoid locking mechanism combined with low-level RFID coding (F40), meaning the switch can recognise any actuator within the F40 coding family. This makes it suitable for general-purpose safety applications where flexibility and interchangeability are important while still maintaining compliance with EN ISO 14119 safety requirements.
With its reinforced technopolymer housing, compact industrial design, and IP67/IP69K protection rating, the NSD3ST1SMK-F40 is ideal for robotic cells, packaging machinery, conveyors, and OEM equipment requiring dependable guard locking and safety interlocking performance.
Key Advantages
- Low-level RFID coding (F40) allows multiple compatible actuators within the same family.
- 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).
- High mechanical holding force up to approx. 2100 N in typical NS configurations.
- Suitable for series connection in safety chains for complex machine layouts.
Key Features
- Pizzato NS-series safety interlock switch with locking.
- Model: NSD3ST1SMK-F40.
- RFID low coding actuator recognition (F40).
- De-energised solenoid guard locking (fail-safe design).

- Auxiliary release for maintenance and emergency access.
Reliable Machine Guarding and Safety Control
The Pizzato NSD3ST1SMK-F40 ensures machinery only operates when protective guards are correctly closed and safely monitored. When the actuator is detected and the locking system is engaged, the safety outputs allow controlled machine operation under safe conditions.
If the guard is opened or the locking condition is removed, the system triggers an immediate safe stop. Continuous monitoring of actuator and lock status ensures reliable integration into PLC-based safety architectures used in industrial automation environments.
Typical Applications
- Industrial automation machinery.
- Robotic safety enclosures.
- Packaging and production systems.
- Conveyor and material handling systems.
- OEM machine building applications.
- General machine safety guarding systems.
