Why Choose the Pizzato NSD3ST1SQK-F41 Safety Interlock Switch?
The Pizzato NSD3ST1SQK-F41 is a compact and high-security RFID safety interlock switch with guard locking designed for industrial machine safety applications requiring reliable guard monitoring, controlled access, and strong anti-tamper protection. It is part of the advanced Pizzato NS NS-series safety locking switch family, widely used in OEM machinery, robotics, and automated production systems.
This model operates using a de-energised solenoid locking mechanism combined with high-level RFID coding (F41). Unlike low-coded versions, F41 provides a unique actuator pairing system, meaning the switch only recognises its specifically paired actuator, significantly increasing protection against tampering and unintended activation in safety-critical environments.
With its reinforced technopolymer housing, compact industrial design, and IP67/IP69K protection rating, the NSD3ST1SQK-F41 is ideal for robotic cells, packaging machinery, conveyors, and OEM equipment where high-integrity guard locking and dependable safety interlocking are required.
Key Advantages
- High-level RFID coding (F41) for unique actuator pairing and enhanced anti-tamper protection.
- Solenoid guard locking with fail-safe de-energised release principle.
- Dual safety outputs (OS1/OS2) for redundant guard status monitoring.
- Integrated diagnostic outputs for actuator and lock status (O3/O4 depending on configuration).
- High mechanical holding force suitable for demanding industrial guarding applications.
- Suitable for series connection in safety chains for complex automation systems.
Key Features
- Pizzato NS-series safety interlock switch with locking.
- Model: NSD3ST1SQK-F41.
- RFID high coding actuator recognition (F41 unique pairing).
- De-energised solenoid guard locking (fail-safe design).

- 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 NSD3ST1SQK-F41 ensures machinery only operates when protective guards are correctly closed and securely locked. When the uniquely coded 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.
- High-security machine guarding systems.
