NS D3AZ1DMK-F40 Pizzato NS series safety locking switch, with actuator

Why Choose the Pizzato NS D3AZ1DMK-F40 Safety Locking Switch?

The Pizzato NS D3AZ1DMK-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, electronic safety outputs and solenoid-operated guard locking in a compact technopolymer housing.

This model uses the D working method, meaning the actuator remains locked when the solenoid is de-energised. Its Mode 1 operating logic activates the OS safety outputs when the protective guard is locked, making it suitable for applications where access must remain prevented until the machine safety system permits release.

The NS D3AZ1DMK-F40 is supplied with the VN NS-F40 universal actuator with low coding level. It also features a front screw auxiliary release, side-facing M12 connection and comprehensive electronic status monitoring, providing machine builders with a robust and flexible guard-locking solution for automated industrial equipment.

Reliable RFID Guard Locking for Industrial Machinery

The Pizzato NS series combines contactless RFID actuator detection with solenoid-controlled mechanical locking, allowing the safety control system to monitor both the position and locked condition of a protective guard. With the D working method used by the NS D3AZ1DMK-F40, the actuator is retained when the solenoid is de-energised, providing a defined locking state for machinery requiring controlled access.

Dual safety inputs and outputs support integration into electronic safety architectures, while separate O3 and O4 outputs communicate actuator-inserted and actuator-locked conditions. The front screw auxiliary release and 12-pole M12 connection further simplify installation, commissioning and maintenance in industrial machine-building applications.

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 installations requiring solenoid-controlled guard locking.
