Why Choose the Pizzato NSD4SE1SA5-F41 Safety Interlock Switch?
The Pizzato NSD4SE1SA5-F41 is a high-performance RFID safety interlock switch with guard locking designed for advanced machine safety applications in industrial automation systems. As part of the Pizzato NS NS-series safety locking switch family, it provides secure actuator recognition, reliable guard locking, and precise safety signal monitoring for modern automated machinery.
This model is engineered for applications where machine guards must remain locked during hazardous operating cycles. It combines a solenoid-controlled locking mechanism with high-level RFID-coded actuator technology (F41 coding), ensuring strong tamper resistance and consistent safety performance in demanding industrial environments.
With its robust technopolymer housing and industrial-grade sealing, the NSD4SE1SA5-F41 is ideal for robotic cells, packaging machines, and automated production lines requiring SIL/PL-rated safety functions and reliable access control.
Key Advantages
- High-security RFID-coded actuator system (F41 high coding level) for tamper-resistant operation.
- Integrated solenoid guard locking mechanism for controlled machine access.
- Dual-channel safety outputs for redundant monitoring and safe operation.
- Real-time feedback of guard closed and locked status.
- Designed for integration into modern safety PLC architectures.
- Rugged industrial construction for harsh environments.
Key Features
- Pizzato NS-series safety interlock switch with locking.
- Model: NSD4SE1SA5-F41.
- RFID-coded actuator system with high-level (F41) security coding.
- Solenoid-controlled guard locking (de-energised fail-safe principle).
- M12 multi-pole industrial connector interface.
- Safety outputs OS1/OS2 with diagnostic signals (O3/O4).
- Auxiliary release function for emergency or maintenance access.
Reliable Machine Guarding and Safety Control
The Pizzato NSD4SE1SA5-F41 ensures that machinery cannot operate unless protective guards are properly closed and locked. When the actuator is engaged and locked, the safety outputs enable machine operation; if the guard is opened, the system triggers an immediate safe stop.
Its RFID high-level coding significantly reduces tampering risks, while integrated diagnostics continuously monitor guard status and locking condition for safety controllers and PLC systems. The NS-series architecture supports high functional safety performance in industrial automation environments.
Typical Applications
- Robotic safety cell guarding systems.
- Industrial machine guard locking systems.
- Automated production lines and conveyors.
- Packaging and processing machinery.
- OEM machine safety integration.
- High-risk industrial automation environments.
