NS D3AZ1SPK-F40 Pizzato NS series safety locking switch, with actuator

Why Choose the Pizzato NS D3AZ1SPK-F40 Safety Locking Switch?

The Pizzato NS D3AZ1SPK-F40 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, solenoid-operated guard locking and electronic safety outputs in a compact technopolymer housing.

This model uses the D working method, with the actuator locked when the solenoid is de-energised. It operates in Mode 1, where the OS safety outputs are active with the protective guard locked, providing a dependable architecture for machinery where access must remain restricted until the safety system permits release.

The NS D3AZ1SPK-F40 is supplied complete with the VN NS-F40 universal actuator with low coding level. It also features a front screw auxiliary release, downward-facing electrical connection and an 8-pole M12 connector for stand-alone connections, providing a practical and robust guard-locking solution for modern industrial machinery.

Reliable RFID Guard Locking for Industrial Machinery

Pizzato NS series safety switches combine RFID actuator detection with mechanical guard locking, enabling the machine safety system to monitor both the position and locked condition of a protective guard. With the D working method used by the NS D3AZ1SPK-F40, the actuator remains locked while the solenoid is de-energised, providing controlled access to hazardous machine areas.

The dual IS1–IS2 safety inputs and OS1–OS2 safety outputs allow the switch to form part of an electronic safety architecture, while the O3 and O4 signalling outputs provide separate information about actuator insertion and locking status. Together with the front auxiliary release and M12 connection, these features make the NS D3AZ1SPK-F40 a versatile solution for automated machine guarding.

Typical Applications

• Machine guard and access-door interlocking.
• Automated production and assembly machinery.
• Robotic cells and guarded automation systems.
• Packaging and processing equipment.
• Material handling and conveyor systems.
• Machine tools and manufacturing equipment.
• Industrial machinery requiring solenoid-controlled guard locking.
