NS D3SE1SMK-F41 Pizzato NS series safety locking switch, with actuator

Why Choose the Pizzato NS D3SE1SMK-F41 Safety Locking Switch?

The Pizzato NS D3SE1SMK-F41 is an advanced RFID safety locking switch with separate actuator designed for monitoring and locking protective guards, doors and access points on industrial machinery. Part of the Pizzato NS series, it combines contactless RFID actuator detection, solenoid-controlled guard locking and electronic safety monitoring in a compact industrial housing.

This configuration uses the D operating principle, whereby the actuator is locked when the electromagnet is de-energised. This makes the switch suitable for applications where a protective guard must remain securely retained until the machine safety system permits access. Electronic safety inputs and outputs provide straightforward integration with compatible safety controllers and safety PLCs.

The NS D3SE1SMK-F41 is supplied with the VN NS-F41 high-level coded RFID actuator and provides a maximum locking force of 2,100 N. The switch also combines a front key-operated auxiliary release with a rear escape-release pushbutton, providing controlled external unlocking together with a means of releasing the guard from inside a protected area.

Reliable Guard Locking with Controlled and Emergency Release

Pizzato NS series switches combine coded RFID actuator detection with mechanical guard locking, allowing the machine safety system to monitor the presence of the actuator and the locked condition of the protective guard. The high-level coded F41 actuator helps reduce the possibility of manipulation, while the D operating principle provides de-energised-electromagnet guard retention.

The combination of a front key-operated auxiliary release and rear escape-release pushbutton makes the NS D3SE1SMK-F41 particularly suitable for guarded areas where controlled maintenance access and internal emergency egress are important. Its electronic safety interface and M12 connection also support efficient integration into automated industrial safety systems.

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.
