Why Choose the Pizzato NSD4AZ1SMK-F40 Safety Interlock Switch?
The Pizzato NSD4AZ1SMK-F40 is a reliable RFID safety interlock switch with solenoid guard locking, designed for industrial machine safety applications where dependable access control and actuator monitoring are required. Manufactured by Pizzato Elettrica, it ensures that hazardous machinery remains securely locked until all safety conditions are satisfied.
This model belongs to the Pizzato NS series of safety locking switches with integrated RFID actuator detection and de-energised solenoid locking. It is widely used in OEM machinery, robotics, and automation systems where safe guarding and simplified wiring architecture are essential.
The NSD4AZ1SMK-F40 operates in a D working method configuration, meaning the actuator is locked with a de-energised solenoid and safety outputs are enabled only when the guard is correctly closed and secured. The F40 actuator version uses a low-coded universal actuator, making it suitable for standard industrial applications where flexibility is required. {index=1}
