Why Choose the Pizzato NSD4CE1STK-N003 Safety Interlock Switch?
The Pizzato NSD4CE1STK-N003 is a compact RFID safety interlock switch with solenoid guard locking and integrated STK control device unit, designed for industrial machinery that requires reliable access control, actuator monitoring, and integrated operator commands. Manufactured by Pizzato Elettrica, it delivers high-performance machine safety in a single, space-saving device.
This model belongs to the Pizzato NS series safety switches with integrated control devices (STK-N003 configuration). It combines RFID-coded guard locking with a built-in operator interface featuring illuminated pushbuttons and an emergency stop function, making it ideal for OEM machine builders and industrial automation systems.
The NSD4CE1STK-N003 operates in a D working method configuration, meaning the actuator is locked via a de-energised 24 Vdc solenoid. Safety outputs are enabled only when the guard is closed, the actuator is correctly detected, and the system confirms safe operating conditions. {index=1}
Key Advantages
- Integrated RFID safety interlock system with guard locking.

Integrated Safety and Machine Control
The NSD4CE1STK-N003 combines RFID guard locking with a built-in operator interface, reducing the need for external control panels. This helps machine builders simplify wiring, reduce cabinet space, and improve operator access directly at the machine guard.
The integrated emergency stop provides immediate shutdown capability at the point of operation, while the pushbuttons support local machine control and signaling functions. {index=2}
