Why Choose the Pizzato NSD4AZ1SMK-F41 Safety Interlock Switch?
The Pizzato NSD4AZ1SMK-F41 is a high-reliability RFID safety interlock switch with solenoid guard locking, designed for industrial machine safety applications requiring strong actuator coding, dependable locking force, and precise status feedback. Manufactured by Pizzato Elettrica, it provides secure protection by ensuring machinery remains locked until safe conditions are achieved.
This model belongs to the Pizzato NS series of safety locking switches with integrated RFID high-coded actuator recognition (F41 level) and de-energised solenoid locking. It is widely used in OEM machinery, robotics, and automated production systems where high safety integrity and tamper resistance are essential.
The NSD4AZ1SMK-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 correctly closed and the actuator is properly detected and locked, ensuring a high level of functional safety. {index=1}
