Why Choose the Pizzato NSD4CE1SPK-F40 Safety Interlock Switch?
The Pizzato NSD4CE1SPK-F40 is a compact RFID safety interlock switch with solenoid guard locking, designed for industrial machinery requiring reliable door protection, actuator detection, and controlled access to hazardous areas. Manufactured by Pizzato Elettrica, it is part of the NS series safety locking switches widely used in OEM automation and machine safety systems.
This model belongs to the SPK configuration of the NS series, combining a standard safety interlock body with an RFID-coded actuator system and a robust solenoid locking mechanism. The F40 coding level provides flexible actuator compatibility for general industrial applications.
The NSD4CE1SPK-F40 operates using a D working principle, where the actuator is locked via a de-energised 24 Vdc solenoid. Safety outputs are enabled only when the guard is closed, the actuator is detected, and the system confirms a safe machine state. {index=1}

Reliable Machine Guarding for Industrial Systems
The NSD4CE1SPK-F40 ensures that machine guards remain locked until hazardous movement has completely stopped. The F40 RFID coding allows multiple compatible actuators within the same coding family, making it suitable for flexible maintenance and general-purpose industrial use.
Its safety outputs integrate with PLC-based safety controllers, enabling continuous monitoring of door status, actuator engagement, and lock condition in automated production environments. {index=2}
