Why Choose the Pizzato NSD6AZ1SMK-F41 Safety Interlock Switch?
The Pizzato NSD6AZ1SMK-F41 is a high-reliability RFID safety interlock switch with solenoid locking designed for advanced machine guarding applications in industrial automation systems. Manufactured by Pizzato Elettrica, it belongs to the NS series safety switch family widely used for protecting operators and controlling access to hazardous machinery.
This device is typically installed on safety doors, hinged guards, sliding panels, and machine access points. It prevents machinery from operating while a guard is open, supporting compliance with EN ISO 14119 functional safety standards and modern industrial safety architectures.
The NSD6AZ1SMK-F41 uses a high-level coded F41 RFID actuator system, meaning it recognises only a single uniquely paired actuator for maximum tamper resistance and high safety integrity in demanding environments.
Key Advantages
- High-security RFID safety interlock with solenoid locking.
- F41 high-level coded actuator for maximum anti-tamper protection.
- Designed for industrial machine safety and automation systems.
- Reliable dual-channel safety outputs for PLC integration.
- Real-time 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.
- AZ configuration housing for flexible installation orientation.
- Industrial sealed housing for harsh environments.
Advanced Machine Guard Safety Control
The NSD6AZ1SMK-F41 ensures machinery remains safely disabled whenever guards are open or not properly secured. The solenoid locking mechanism prevents access until safe operating conditions are achieved, while the RFID system guarantees that only the correct F41-coded actuator can operate the switch.
This makes it suitable for high-integrity industrial environments where safety, reliability, and tamper resistance are essential. It integrates seamlessly with safety PLCs to provide continuous monitoring of guard status and locking condition.
Typical Applications
- Industrial automation production lines.
- Robotics safety cells and machine guarding systems.
- CNC machining centres and tooling equipment.
- Packaging and processing machinery.
- Material handling and conveyor systems.
- High-security safety doors and access panels.
