Why Choose the Pizzato NSD3ST1SQK-F40 Safety Interlock Switch?
The Pizzato NSD3ST1SQK-F40 is a high-performance RFID safety interlock switch with guard locking designed for industrial machine safety applications requiring secure access control, reliable guard status monitoring, and consistent safety feedback. It is part of the established 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 recognises any actuator within the same F40 family. This provides flexibility in installation and maintenance while still meeting EN ISO 14119 requirements for industrial safety systems.
With its compact technopolymer housing, robust internal mechanics, and IP67/IP69K protection rating, the NSD3ST1SQK-F40 is suitable for robotic cells, packaging machinery, conveyors, and OEM automation equipment where reliable guard locking and interlocking performance are essential.
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 depending on configuration).
- High mechanical holding force suitable for demanding machine guarding applications.
- Suitable for series connection in safety chains for complex industrial systems.
Key Features
- Pizzato NS-series safety interlock switch with locking.
- Model: NSD3ST1SQK-F40.
- RFID low coding actuator recognition (F40).
- De-energised solenoid guard locking (fail-safe design).
- Integrated M12 industrial connector interface (typical NS architecture).
- Safety outputs OS1/OS2 with diagnostic signals O3/O4.
- Auxiliary release for maintenance and emergency access.
Reliable Machine Guarding and Safety Control
The Pizzato NSD3ST1SQK-F40 ensures machinery only operates when protective guards are correctly closed and securely locked. 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 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.
