Why Choose the Pizzato NSD5AZ1SMK-F41 Safety Interlock Switch?
The Pizzato NSD5AZ1SMK-F41 is an advanced RFID safety interlock switch with solenoid guard locking, designed for high-performance industrial machine safety applications requiring strong actuator coding, reliable door monitoring, and secure access control. Manufactured by Pizzato Elettrica, it ensures hazardous machinery remains safely locked until all safety conditions are met.
This model belongs to the Pizzato NS series of safety locking switches featuring high-coded RFID actuator recognition (F41 level) and de-energised solenoid locking technology. It is widely used in OEM machinery, robotics, and automated production systems where high safety integrity and tamper resistance are essential.
The NSD5AZ1SMK-F41 operates in a D working method configuration, meaning the actuator is locked when the solenoid is de-energised (24 Vdc). Safety outputs are enabled only when the guard is closed, the actuator is correctly identified, and the locking state is confirmed. {index=1}

High-Security Guard Locking for Industrial Automation
The Pizzato NSD5AZ1SMK-F41 prevents access to hazardous machine areas by ensuring the guard remains locked until safe conditions are confirmed. Its high-coded RFID system significantly reduces the risk of bypassing or actuator substitution.
The integrated safety outputs allow direct connection to safety PLCs or controllers, enabling real-time monitoring of guard status, actuator presence, and locking condition within automated production systems.
Typical Applications
- Industrial robotic safety cells.
- Automated manufacturing systems.
- Packaging and processing machinery.
- Machine tools requiring high safety integrity.
- OEM automation equipment.
- Material handling and conveyor safety systems.
