Why Choose the Pizzato NSD4SE1SMK Safety Interlock Switch?
The Pizzato NSD4SE1SMK is a high-reliability RFID safety interlock switch with guard locking designed for industrial machine safety applications where controlled access and robust protection are required. As part of the Pizzato NS NS-series safety locking switch family, it provides secure actuator recognition, electromechanical locking, and dependable safety signal monitoring for automated machinery.
This model uses a de-energised solenoid locking principle combined with RFID-coded actuator technology, ensuring that the guard remains locked during hazardous machine operation and can only be released under safe conditions. It is designed for demanding industrial environments where safety integrity and tamper resistance are essential.
With its rugged technopolymer housing, compact form factor, and industrial-grade IP protection, the NSD4SE1SMK is widely used in robotic cells, packaging systems, conveyors, and OEM machinery requiring certified safety interlocking solutions.
Key Advantages
- High-security RFID-coded actuator system (F41 high coding level) for strong tamper resistance.
- Integrated solenoid guard locking mechanism for safe machine access control.
- Dual-channel safety outputs (OS1/OS2) for redundant safety monitoring.
- Real-time feedback of guard closed and locked status (O3/O4 signals).
- Complies with EN ISO 14119 machine safety standards.
- Robust industrial design suitable for harsh environments.
Key Features
- Pizzato NS-series safety interlock switch with locking.
- Model: NSD4SE1SMK.
- RFID-coded actuator recognition (F40/F41 configuration family).
- De-energised solenoid guard locking (fail-safe operation).
- M12 multi-pole industrial connector interface.
- Safety outputs OS1/OS2 with diagnostic outputs O3/O4.
- Auxiliary release function for maintenance and emergency access.
Reliable Machine Guarding and Safety Control
The Pizzato NSD4SE1SMK 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-coded system provides strong protection against tampering, 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 applications.
Typical Applications
- Industrial machine guard locking systems.
- Robotic safety cell enclosures.
- Packaging and production machinery.
- Conveyor and material handling systems.
- OEM machine safety integration.
- General industrial automation equipment.
