Why Choose the Pizzato NSD4ST1SA10-F41 Safety Interlock Switch?
The Pizzato NSD4ST1SA10-F41 is a high-reliability RFID safety interlock switch with guard locking designed for industrial machine safety applications requiring secure access control and dependable guard monitoring. It is part of the advanced Pizzato NS NS-series safety locking switch platform, engineered for robust actuator recognition, solenoid locking, and continuous safety feedback in automated systems.
This model operates using a de-energised solenoid locking principle combined with high-level RFID coding (F41), ensuring strong tamper resistance and safe retention of machine guards during hazardous operation. It is designed according to EN ISO 14119 requirements and widely used in modern safety-rated industrial machinery.
With its durable technopolymer housing, compact footprint, and IP67/IP69K protection rating, the NSD4ST1SA10-F41 is suitable for robotic systems, packaging machinery, conveyors, and OEM automation equipment where reliable guard locking and safety interlocking are essential.
Key Advantages
- High-security RFID-coded actuator system (F41 coding level) for strong anti-tamper protection.
- Solenoid guard locking with fail-safe de-energised release principle.
- Dual safety outputs (OS1/OS2) for redundant monitoring of guard status.
- Integrated diagnostic outputs for actuator and lock status (O3/O4).
- Designed for PL e / SIL 3 safety architectures in industrial automation systems.
- Supports series connection in safety chains for complex machine systems.

Reliable Machine Guarding and Safety Control
The Pizzato NSD4ST1SA10-F41 ensures machinery only operates when protective guards are correctly closed and locked. When the RFID-coded actuator is detected and locking 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 diagnostics monitor actuator status and lock condition, ensuring reliable integration into PLC-based safety architectures 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.
