Why Choose the Pizzato NSD4AZ1SMK Safety Interlock Switch?
The Pizzato NSD4AZ1SMK is a high-reliability RFID safety interlock switch with guard locking, designed for industrial machine safety applications where robust access control and dependable actuator recognition are required. Manufactured by Pizzato Elettrica, it ensures that hazardous machinery remains securely locked until all safety conditions are met.
This model belongs to the Pizzato NS series of safety locking switches, combining high-coded RFID actuator technology, solenoid-driven guard locking, and compact industrial housing. It is widely used in OEM machinery, robotics, and automation systems where reliable safety interlocking is required to protect operators and equipment.
The NSD4AZ1SMK operates in a D working method configuration, meaning the actuator is locked using a de-energised solenoid and safety outputs are enabled only when the guard is correctly closed and secured. The system is designed to meet high safety integrity requirements in modern industrial environments. {index=1}
