Why Choose the Pizzato NS D3CE1SPK-F41 Safety Locking Switch?
The Pizzato NS D3CE1SPK-F41 is an advanced RFID safety locking switch with separate actuator designed for reliable monitoring and locking of protective guards, doors and access points on industrial machinery. Part of the Pizzato NS series, it combines contactless RFID actuator recognition with solenoid-controlled guard locking and electronic safety outputs in a compact, glass-fibre-reinforced technopolymer housing.
This model uses the D operating principle, meaning the actuator is locked when the electromagnet is de-energised. In Mode 1, the OS1 and OS2 safety outputs are active when the actuator is inserted and the protective guard is locked, providing dependable monitoring for machinery where access must remain restricted until safe release conditions have been established.
The NS D3CE1SPK-F41 is supplied with the VN NS-F41 high-level coded RFID actuator and provides a maximum locking force before breakage of 2,100 N. It also combines an orientable front screwdriver-operated auxiliary release with a rear escape-release pushbutton, while its downward-facing 8-pole M12 connector provides a convenient stand-alone connection for industrial machine-safety systems.

Reliable Guard Locking with Escape Release
Pizzato NS series switches combine coded RFID actuator detection with mechanical guard locking, enabling a machine safety system to monitor both the presence of the actuator and the locked condition of the protective guard. The high-level coded F41 actuator helps increase resistance to foreseeable manipulation, while the de-energised-electromagnet locking principle provides controlled retention of the guard.
The combination of a front auxiliary release and rear escape-release pushbutton makes the NS D3CE1SPK-F41 particularly suitable for larger guarded areas where personnel may enter the protected space. Dual safety inputs and outputs, separate actuator and lock status signals, and the M12 connection support straightforward integration into modern automated safety architectures.
Typical Applications
- Machine guard and access-door interlocking.
- Robotic cells and enclosed automation areas.
- Automated production and assembly machinery.
- Packaging and processing equipment.
- Material handling and conveyor systems.
- Machine tools and manufacturing equipment.
- Guarded areas requiring an internal escape-release facility.
