Why Choose the Pizzato NSD3ST1SPK-F40 Safety Interlock Switch?
The Pizzato NSD3ST1SPK-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 well-established Pizzato NS NS-series safety locking switch family, widely used in OEM machinery and automation systems for dependable protection of moving equipment.
This model operates using a de-energised solenoid locking mechanism combined with low-level RFID coding (F40). The F40 coding means the switch can recognise any actuator within the same F40 family, making it a flexible and cost-effective solution for general-purpose safety applications while still meeting EN ISO 14119 machine safety standards.
With its reinforced technopolymer housing, compact industrial design, and IP67/IP69K protection rating, the NSD3ST1SPK-F40 is ideal for robotic cells, packaging machinery, conveyors, and OEM equipment requiring reliable guard locking and consistent interlocking performance.
Key Advantages
- Low-level RFID coding (F40) allows interchangeable 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 (variant dependent).
- Suitable for series connection in safety chains for complex machinery layouts.

Reliable Machine Guarding and Safety Control
The Pizzato NSD3ST1SPK-F40 ensures machinery only operates when protective guards are correctly closed and safely monitored. When the RFID-coded actuator is detected and the locking system 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. Continuous monitoring of actuator and lock status ensures reliable integration into PLC-based safety architectures used in industrial automation systems.
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.
