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}
Key Advantages
- RFID actuator system with F40 low coding flexibility.
- Integrated solenoid guard locking for machine safety.
- Compact SPK housing for easy installation on machine guards.
- Reliable detection of door status and actuator insertion.
- Suitable for a wide range of industrial automation systems.
- Robust design for harsh factory environments.
Key Features
- Pizzato NS series safety interlock switch.
- Model: NSD4CE1SPK-F40.
- RFID-coded actuator system (F40 low coding).
- 2 safety inputs (IS1–IS2).
- 2 safety outputs (OS1–OS2).
- 1 actuator inserted output (O3).

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}

Frequently Asked Questions
What is the Pizzato NSD4CE1SPK-F40 used for?
It is used for safety interlocking and guard locking in industrial machines to prevent access to hazardous areas.
What does F40 mean?
F40 refers to a low-level coded RFID actuator system where multiple actuators of the same type are interchangeable.
How does the locking system work?
The solenoid keeps the guard locked and releases it only when safe machine conditions are confirmed.
Is it suitable for industrial environments?
Yes, it is designed with rugged technopolymer housing and high IP protection ratings for demanding environments.
What is the difference between SPK and SMK variants?
SPK and SMK are both compact NS safety interlock formats; SPK is typically used for standard configurations, while SMK may vary depending on connection or feature set.
Trusted in Industrial Automation Worldwide
Pizzato NS series RFID safety interlock switches are widely used in modern automation systems to ensure reliable machine guarding, actuator detection, and safe access control.
