Why Choose the Pizzato NSD4AZ1SMK-F41 Safety Interlock Switch?
The Pizzato NSD4AZ1SMK-F41 is a high-performance RFID safety interlock switch with solenoid guard locking, designed for industrial machine safety applications where secure access control, high actuator coding, and reliable monitoring are essential. 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 safety locking switches with integrated RFID actuator recognition and de-energised solenoid locking technology. It is widely used in OEM machinery, robotics, and automated production systems requiring high safety integrity and dependable guard status feedback.
The NSD4AZ1SMK-F41 operates in a D working method configuration, meaning the actuator is locked using a de-energised solenoid. Safety outputs are enabled only when the guard is correctly closed and secured. The F41 actuator provides a high-coded RFID level, offering enhanced tamper resistance compared to low-coded variants. {index=1}
