Why Choose the Pizzato NSD4SE1DMK-F41 Safety Interlock Switch?
The Pizzato NSD4SE1DMK-F41 is a high-reliability 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 range, it provides secure actuator recognition, robust guard locking, and dependable safety signal monitoring for modern machinery.
This model is engineered for applications where machine guards must remain securely locked during hazardous operation. It uses a solenoid-controlled locking mechanism combined with high-level RFID-coded actuator detection to ensure strong tamper resistance and consistent safety performance in demanding industrial environments.
With its durable technopolymer housing and IP-rated sealing, the NSD4SE1DMK-F41 is suitable for robotic cells, automated production lines, and packaging machinery 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 safety control.
- Integrated solenoid guard locking mechanism for secure machine access.
- Dual-channel safety outputs for redundant monitoring.
- Real-time feedback of guard closed and locked status.
- Designed for integration into safety PLC architectures.
- Rugged industrial design for harsh environments.
Key Features
- Pizzato NS-series safety interlock switch with locking.
- Model: NSD4SE1DMK-F41.
- RFID-coded actuator system with high-level (F41) coding.
- Solenoid-controlled guard locking (de-energised lock principle).
- M12 multi-pole industrial connector interface.
- Safety outputs OS1/OS2 with diagnostic signals (O3/O4).
- Auxiliary release function for emergency access.
Reliable Machine Guarding and Safety Control
The Pizzato NSD4SE1DMK-F41 ensures that hazardous 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 or the actuator is removed, the system triggers an immediate safe stop.
Its RFID high-level coding significantly reduces tampering risks, while integrated diagnostics provide continuous monitoring of guard status and locking condition for safety controllers and PLC systems. Based on NS-series architecture, it supports high safety integrity levels used in industrial automation.
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.
