Why Choose the Pizzato NSD5AZ1DMK-F41 Safety Interlock Switch?
The Pizzato NSD5AZ1DMK-F41 is a high-performance RFID safety interlock switch with solenoid locking, designed for advanced machine guarding applications in industrial automation systems. Manufactured by Pizzato Elettrica, it is part of the NS series safety switch family used to protect operators and ensure machinery only operates when protective guards are securely closed.
This device is typically installed on safety doors, hinged guards, sliding panels, and machine access points. It prevents hazardous machinery from operating while the guard is open, supporting compliance with EN ISO 14119 functional safety standards and modern industrial machine safety architectures.
The NSD5AZ1DMK-F41 uses a high-level coded F41 RFID actuator system, meaning it recognises only a single uniquely paired actuator for maximum anti-tamper protection and high safety integrity in demanding industrial environments.
Key Advantages
- High-security RFID safety interlock with solenoid locking.
- F41 high-level coded actuator for maximum tamper resistance.
- Designed for industrial machine safety and automation systems.
- Reliable dual-channel safety outputs for PLC integration.
- Integrated monitoring of door position and lock status.
- Robust industrial construction for harsh environments.
Key Features
- Pizzato NS series safety interlock switch with locking function.
- Solenoid locking mechanism with fail-safe de-energised release principle.
- High-level coded RFID actuator system (F41 type).
- 2 safety outputs (OS1–OS2).
- Actuator insertion and lock status signalling outputs.
- Optimised AZ configuration housing for flexible mounting orientation and installation layouts.
- Industrial sealed housing for demanding environments.
Advanced Machine Guard Safety Control
The NSD5AZ1DMK-F41 ensures machinery remains safely disabled whenever guards are open or not correctly secured. The solenoid locking mechanism prevents access until safe operating conditions are achieved, while the RFID system ensures only the correct F41-coded actuator can operate the switch.
This makes it suitable for high-security industrial environments where safety integrity, reliability, and tamper resistance are essential. It integrates with safety PLCs to provide real-time monitoring of guard status and locking condition.
Typical Applications
- Industrial automation production lines.
- Robotics safety cells and guarded machinery.
- CNC machining centres and tooling systems.
- Packaging and processing machinery.
- Material handling and conveyor systems.
- High-security safety doors and access panels.
