Why Choose the Pizzato NSD3ST1SMK Safety Interlock Switch?
The Pizzato NSD3ST1SMK is a robust RFID safety interlock switch with guard locking designed for industrial machine safety applications that require reliable door monitoring, controlled access, and high-integrity safety signalling. It is part of the widely used Pizzato NS NS-series safety locking switch family, engineered for OEM machinery, automation systems, and safety-critical production environments.
This version uses a de-energised solenoid locking mechanism combined with standard actuator recognition architecture (model variant dependent, typically paired with F40/F41 coding families in NS platforms). It is designed to ensure machines only operate when protective guards are properly closed and locked, supporting compliance with EN ISO 14119 machine safety standards.
With its compact reinforced technopolymer housing, industrial-grade sealing, and IP67/IP69K protection rating, the NSD3ST1SMK is ideal for robotic cells, packaging lines, conveyors, and OEM equipment requiring dependable guard locking and interlocking performance in demanding environments.
Key Advantages
- Reliable solenoid guard locking for machine safety applications.
- Compatible with NS-series RFID actuator systems (F40/F41 depending on configuration).
- Dual safety outputs (OS1/OS2) for redundant monitoring of guard status.
- Integrated diagnostic outputs for actuator and lock condition (O3/O4).
- High protection rating: IP67 / IP69K for harsh industrial environments.
- Designed for integration into safety PLC and industrial automation systems.
Key Features
- Pizzato NS-series safety interlock switch with locking.
- Model: NSD3ST1SMK.
- Solenoid-operated guard locking (fail-safe de-energised release).
- RFID-based actuator compatibility (platform dependent).
- M12 industrial connector interface (variant dependent).
- Safety outputs OS1/OS2 with diagnostic signals O3/O4.
- Auxiliary release function for maintenance and emergency access.
Reliable Machine Guarding and Safety Control
The Pizzato NSD3ST1SMK ensures machinery only operates when protective guards are correctly closed and safely locked. When the actuator is engaged and the locking system is active, the safety outputs permit 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 modern 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.
